Maintenance of the gearbox of the dual-screw extruder
1. The gear box of the dual-screw extruder should be well-ventilated, and the working environment temperature should be within the range of 5-35 °C.
2. Always check the oil quantity of the gear lubricating oil in the box to ensure that the transmission parts in the box are well lubricated.
3. Pay attention to check the bearing parts of the box frequently. The oil temperature of the oil tank of the transmission box should not exceed 70 ºC during operation.
4. The newly put into use gearbox needs to replace the lubricating oil after 250 hours of operation. The oil change time depends on the state of the oil. It is recommended to replace it after 4000-8000 hours of operation or once a year.
5. The gearbox of the dual-screw extruder needs to be regularly maintained and inspected once a year 

Operating Process
1. The gear on the input shaft is driven by the motor and starts to rotate.
2. The rotating input gear meshes with other gears inside the gearbox, transmitting power.
3. Different-sized gears within the gearbox are combined to form a gear train. Through continuous meshing and rotation, the high-speed, low-torque power from the input shaft gradually converts into low-speed, high-torque output.
4. The output shaft is connected to the last gear and transfers the output torque to the load.
5. Gear reduction gearboxes typically include lubrication and cooling systems to ensure smooth operation and prevent overheating and damage.
6. Our extruder gearbox converts high-speed, low-torque power into low-speed, high-torque output by changing the size ratios and meshing arrangements of different gears, achieving the function of speed reduction.

Types of Gearboxes:
Based on customer requirements, gear reduction gearboxes can be classified according to the size of the output shaft, center distance of the output shaft, output speed, and torque. Alternatively, we can provide several commonly used types of gearboxes for customers to choose from.

worm reducer

What is a worm gear reducer gearbox?

A worm gear reducer gearbox is a mechanical device that uses a worm gear and a worm to reduce the speed of a rotating shaft. The gear reducer gearbox can increase the output torque of the engine according to the gear ratio. This type of gear reducer gearbox is characterized by its flexibility and compact size. It also increases the strength and efficiency of the drive.

Hollow shaft worm gear reducer gearbox

The hollow shaft worm gear reducer gearbox is an additional output shaft connecting various motors and other gearboxes. They can be installed horizontally or vertically. Depending on size and scale, they can be used with gearboxes from 4GN to 5GX.
Worm gear reducer gearboxes are usually used in combination with helical gear reducer gearboxes. The latter is mounted on the input side of the worm gear reducer gearbox and is a great way to reduce the speed of high output motors. The gear reducer gearbox has high efficiency, low speed operation, low noise, low vibration and low energy consumption.
Worm gear reducer gearboxes are made of hard steel or non-ferrous metals, increasing their efficiency. However, gears are not indestructible, and failure to keep running can cause the gear oil to rust or emulsify. This is due to moisture condensation that occurs during the operation and shutdown of the reducer gearbox. The assembly process and quality of the bearing are important factors to prevent condensation.
Hollow shaft worm gear reducer gearboxes can be used in a variety of applications. They are commonly used in machine tools, variable speed drives and automotive applications. However, they are not suitable for continuous operation. If you plan to use a hollow shaft worm gear reducer gearbox, be sure to choose the correct one according to your requirements.

Double throat worm gear

Worm gear reducer gearboxes use a worm gear as the input gear. An electric motor or sprocket drives the worm, which is supported by anti-friction roller bearings. Worm gears are prone to wear due to the high friction in the gear teeth. This leads to corrosion of the confinement surfaces of the gears.
The pitch diameter and working depth of the worm gear are important. The pitch circle diameter is the diameter of the imaginary circle in which the worm and the gear mesh. Working depth is the maximum amount of worm thread that extends into the backlash. Throat diameter is the diameter of the circle at the lowest point of the worm gear face.
When the friction angle between the worm and the gear exceeds the lead angle of the worm, the worm gear is self-locking. This feature is useful for lifting equipment, but may be detrimental to systems that require reverse sensitivity. In these systems, the self-locking ability of the gears is a key limitation.
The double throat worm gear provides the tightest connection between the worm and the gear. The worm gear must be installed correctly to ensure maximum efficiency. One way to install the worm gear assembly is through a keyway. The keyway prevents the shaft from rotating, which is critical for transmitting torque. Then attach the gear to the hub using the set screw.
The axial and circumferential pitch of the worm gear should match the pitch diameter of the larger gear. Single-throat worm gears are single-threaded, and double-throat worm gears are double-throat. A single thread design advances one tooth, while a double thread design advances two teeth. The number of threads should match the number of mating gears.
worm reducer

Self-locking function

One of the most prominent features of a worm reducer gearbox is its self-locking function, which prevents the input and output shafts from being interchanged. The self-locking function is ideal for industrial applications where large gear reduction ratios are required without enlarging the gear box.
The self-locking function of a worm reducer gearbox can be achieved by choosing the right type of worm gear. However, it should be noted that this feature is not available in all types of worm gear reducer gearboxes. Worm gears are self-locking only when a specific speed ratio is reached. When the speed ratio is too small, the self-locking function will not work effectively.
Self-locking status of a worm reducer gearbox is determined by the lead, pressure, and coefficient of friction. In the early twentieth century, cars had a tendency to pull the steering toward the side with a flat tire. A worm drive reduced this tendency by reducing frictional forces and transmitting steering force to the wheel, which aids in steering and reduces wear and tear.
A self-locking worm reducer gearbox is a simple-machine with low mechanical efficiency. It is self-locking when the work at one end is greater than the work at the other. If the mechanical efficiency of a worm reducer gearbox is less than 50%, the friction will result in losses. In addition, the self-locking function is not applicable when the drive is reversed. This characteristic makes self-locking worm gears ideal for hoisting and lowering applications.
Another feature of a worm reducer gearbox is its ability to reduce axially. Worm gears can be double-lead or single-lead, and it is possible to adjust their backlash to compensate for tooth wear.

Heat generated by worm gears

Worm gears generate considerable amounts of heat. It is essential to reduce this heat to improve the performance of the gears. This heat can be mitigated by designing the worms with smoother surfaces. In general, the speed at which worm gears mesh should be in the range of 20 to 24 rms.
There are many approaches for calculating worm gear efficiency. However, no other approach uses an automatic approach to building the thermal network. The other methods either abstractly investigate the gearbox as an isothermal system or build the TNM statically. This paper describes a new method for automatically calculating heat balance and efficiency for worm gears.
Heat generated by worm gears is a significant source of power loss. Worm gears are typically characterized by high sliding speeds in their tooth contacts, which causes high frictional heat and increased thermal stresses. As a result, accurate calculations are necessary to ensure optimal operation. In order to determine the efficiency of a gearbox system, manufacturers often use the simulation program WTplus to calculate heat loss and efficiency. The heat balance calculation is achieved by adding the no-load and load-dependent power losses of the gearbox.
Worm gears require a special type of lubricant. A synthetic oil that is non-magnetic and has a low friction coefficient is used. However, the oil is only one of the options for lubricating worm gears. In order to extend the life of worm gears, you should also consider adding a natural additive to the lubricant.
Worm gears can have a very high reduction ratio. They can achieve massive reductions with little effort, compared to conventional gearsets which require multiple reductions. Worm gears also have fewer moving parts and places for failure than conventional gears. One disadvantage of worm gears is that they are not reversible, which limits their efficiency.

Size of worm gear reducer gearbox

Worm gear reducer gearboxes can be used to decrease the speed of a rotating shaft. They are usually designed with two shafts at right angles. The worm wheel acts as both the pinion and rack. The central cross section forms the boundary between the advancing and receding sides of the worm gear.
The output gear of a worm gear reducer gearbox has a small diameter compared to the input gear. This allows for low-speed operation while producing a high-torque output. This makes worm gear reducer gearboxes great for space-saving applications. They also have low initial costs.
Worm gear reducer gearboxes are one of the most popular types of speed reducer gearboxes. They can be small and powerful and are often used in power transmission systems. These units can be used in elevators, conveyor belts, security gates, and medical equipment. Worm gearing is often found in small and large sized machines.
Worm gears can also be adjusted. A dual-lead worm gear has a different lead on the left and right tooth surfaces. This allows for axial movement of the worm and can also be adjusted to reduce backlash. A backlash adjustment may be necessary as the worm wears down. In some cases, this backlash can be adjusted by adjusting the center distance between the worm gear.
The size of worm gear reducer gearbox depends on its function. For example, if the worm gear is used to reduce the speed of an automobile, it should be a model that can be installed in a small car.

worm reducer

Worm reducer gearbox

Worm reducer gearboxes are commonly used to reduce the Agknx produced by a rotating shaft. They can achieve reduction ratios of five to sixty. In contrast, a single-stage hypoid gear can achieve up to a 120:1 reduction ratio. For further reduction, another type of gearing is used. So, a single stage worm reducer gearbox cannot achieve higher ratios than these.

Mechanics

A worm reducer gearbox is an auxiliary mechanical device that uses worms to reduce the size of a rotating shaft. These worms have a range of tooth forms. One form is a line weave twist surface. Another is a trapezoid based on a central cross section. The trapezoid can be perpendicular to the tooth cross section, or it can be normal to the root cross section. Other forms include involute helicoids and convolute worms, which use a straight line intersecting the involute generating line.
Worm gears are lubricated with a special lubricant. Because worm gears are complex, it’s important to use the correct lubricant. Worm gear manufacturers provide approved lubricants for their gears. Using unapproved gear oil can damage your reducer gearbox’s efficiency. The right lubricant depends on several factors, including load, speed, duty cycle, and expected operating temperatures.
The efficiency of a worm gear reducer gearbox depends on several factors, including losses at gear mesh, losses in the bearings, and windage in the oil seal lip. In addition, the worm gear reducer gearbox’s efficiency varies with ambient temperature and operating temperature. The worm gear reducer gearbox’s efficiency can also vary with the ratio of the load. Moreover, worm gear reducer gearboxes are subject to break-in.
Worm gear reducer gearboxes are used in many different applications. They are typically used in small electric motors, but they’re also used in conveyor systems, presses, elevators, and mining applications. Worm gears are also commonly found in stringed musical instruments.
Worm gears have excellent reduction ratios and high Agknx multiplication, and they’re often used as speed reducer gearboxes in low to medium-speed applications. However, the efficiency of worm gear reducer gearboxes decreases with increasing ratios.

Sizes

Worm reducer gearboxes come in different sizes and tooth shapes. While the tooth shape of one worm is similar to the other, different worms are designed to carry a different amount of load. For example, a circular arc worm may have a different tooth shape than one with a secondary curve. Worm gears can also be adjusted for backlash. The backlash is the difference between the advancing and receding arc.
There are two sizes of worm reducer gearboxes available from Agknx Transmission. The SW-1 and SW-5 models offer ratios of 3.5:1 to 60:1 and 5:1 to 100:1 respectively. The size of the worm reducer gearbox is determined by the required gear ratio.
Worm gears have different thread counts. One is based on the central cross-section of the worm, and the other is on the right. Worm gears can have either a single or double thread. Single-threaded gears will reduce speed by 50 percent, while double-threaded gears will reduce speed by 25 percent.
Worm gear reducer gearboxes are lightweight and highly reliable. They can accommodate a variety of NEMA input flanges and hollow output bore sizes. Worm reducer gearboxes can be found at 6 regional warehouses, with prepaid freight. To make a purchasing decision, you should consider the horsepower and Agknx requirements of your specific application.

Applications

The Worm reducer gearbox market is a global business that is dominated by the North American and European regions. The report provides in-depth information on the market trends, key challenges, and opportunities. It also examines the current state of the industry and projects future market growth. The report is organized into segments based on product type, major geographical regions, and application. It also presents statistics and key data about the market.
Worm gear reducer gearboxes have many applications. They can be used to increase the speed of convey belts. They also help reduce noise. Worm gears have many teeth that touch the gear mesh, which makes them quieter. Moreover, the worm gears require only a single stage reducer gearbox, reducing the number of moving parts in the system.
The worm gear has long life and is suitable for different industries. It is a perfect choice for elevators and other applications that need fast stopping and braking. Its compact size and ability to hold a load make it suitable for these applications. It also prevents the load from free-falling as a result of a sudden braking. Worm gears can also be used in heavy-duty machinery such as rock crushers.
Worm gears are similar to ordinary gears except that they transfer motion at a 90-degree angle. As a result, the worm gears are extremely quiet, making them a suitable option for noise sensitive applications. They are also excellent for low-voltage applications, where the noise is critical.
Worm gears are ideal for applications with space restrictions, because they require fewer gear sets. The worm gears also allow for a smaller gearbox size. Consequently, they are the perfect choice for machines that are space-constrained, such as conveyors and packaging equipment.

Cost

The lifespan of a worm gear reducer gearbox is comparable to other gear reducer gearboxes. Worm gears have a long history of innovation and use in various industries, from shipbuilding to automobile manufacturing. Today, these gear reducer gearboxes are still popular with engineers. However, there are some things to keep in mind before buying one.
In the first place, a worm reducer gearbox needs to be affordable. Generally, a worm reducer gearbox costs about $120. The price varies with the brand name and features. Some products are more expensive than others, so be sure to shop around for the best price. In addition, it is important to consider the quality and design of the worm reducer gearbox before making a purchase.
Worm gear manufacturers have made significant advancements in materials, design and manufacturing. These advancements, along with the use of advanced lubricants, have resulted in significant increases in efficiency. For example, double enveloping worm gear reducer gearboxes have improved efficiency by three to eight percentage points. This improvement was achieved through rigorous testing of manufacturing processes and materials. With these improvements, worm gear reducer gearboxes have become more desirable in today’s market.
Worm reducer gearboxes are extremely versatile and reliable, and are available in a variety of sizes. Domestic manufacturers usually stock a large selection of reducer gearboxes, and are often able to ship them the same day you place your order. Most major domestic worm gear reducer gearbox manufacturers also share some critical mounting dimensions, such as the output shaft diameter, the mounting hole location, and the overall reducer gearbox housing height. Most manufacturers also offer standardized gear ratios. Some manufacturers have also improved gear design and added synthetic lubricants for better performance.
In addition, different tooth shapes of worms can increase their load carrying capacity. They can be used on secondary curves and circular arc cross sections. Moreover, the pitch point defines the boundary of the cross section. The mesh on the receding arc is smoother than that of the advancing arc. However, in the case of negative shifting, most of the mesh is on the receding arc.
worm reducer

Self-locking function

A worm reducer gearbox has a self-locking function. When a worm is fitted with all of its addendum teeth, the total number of teeth in the system should be greater than 40. This self-locking function is achieved through the worm’s rack and pinion mechanism. The worm’s self-locking feature can prevent the load from being dropped and is useful for many applications.
The self-locking function of a worm reducer gearbox is possible for two main reasons. First of all, a worm reducer gearbox uses two or more gears. One gear is placed at the input, and the other gear runs the output shaft. This mechanism produces a torque, which is transmitted to a spur gear.
Worm reducer gearboxes can be used in a variety of industrial applications. Because of their self-locking function, they are useful for preventing back-driving. They are also helpful for lifting and holding loads. Their self-locking mechanism allows for a large gear reduction ratio without increasing the size of a gear box.
Self-locking gears can be used to prevent back-driving and inertial driving. This is useful for many industries and can prevent backdriving. However, one major disadvantage of self-locking gears is their sensitivity to operating conditions. Lubrication, vibration, and misalignment can affect their reliability.
Embodiments of the invention provide a self-locking mechanism that prevents back-driving but allows forward-driving. The self-locking mechanism may comprise first and second ratchet cams disposed about a gear member. A releasable coupling member may be interposed between the gear member and the ratchet cam. This facilitates selective coupling and decoupling.
The worm reducer gearbox has several advantages. Its compact design is ideal for many mechanical transmission systems. It also provides greater load capacity than a cross-axis helical gear mechanism.

  • Paint and lacquer industry
  • Washing agent industry
  • Foodstuff industry (e.g. bread, pasta)
  • Animal-feed industry (dog, cat other animal food 

Maintenance of the gearbox of the dual-screw extruder
1. The gear box of the dual-screw extruder should be well-ventilated, and the working environment temperature should be within the range of 5-35 °C.
2. Always check the oil quantity of the gear lubricating oil in the box to ensure that the transmission parts in the box are well lubricated.
3. Pay attention to check the bearing parts of the box frequently. The oil temperature of the oil tank of the transmission box should not exceed 70 ºC during operation.
4. The newly put into use gearbox needs to replace the lubricating oil after 250 hours of operation. The oil change time depends on the state of the oil. It is recommended to replace it after 4000-8000 hours of operation or once a year.
5. The gearbox of the dual-screw extruder needs to be regularly maintained and inspected once a year 

Operating Process
1. The gear on the input shaft is driven by the motor and starts to rotate.
2. The rotating input gear meshes with other gears inside the gearbox, transmitting power.
3. Different-sized gears within the gearbox are combined to form a gear train. Through continuous meshing and rotation, the high-speed, low-torque power from the input shaft gradually converts into low-speed, high-torque output.
4. The output shaft is connected to the last gear and transfers the output torque to the load.
5. Gear reduction gearboxes typically include lubrication and cooling systems to ensure smooth operation and prevent overheating and damage.
6. Our extruder gearbox converts high-speed, low-torque power into low-speed, high-torque output by changing the size ratios and meshing arrangements of different gears, achieving the function of speed reduction.

Types of Gearboxes:
Based on customer requirements, gear reduction gearboxes can be classified according to the size of the output shaft, center distance of the output shaft, output speed, and torque. Alternatively, we can provide several commonly used types of gearboxes for customers to choose from.

worm reducer

Worm gear reducer gearbox

Cheaper than planetary gearboxes In many cases, worm gear reducer gearboxes are a popular alternative to planetary gearboxes. A worm gear reducer gearbox is a mechanical device with vertical input and output shafts. This allows for very high reduction ratios. They are typically used in high-reduction situations such as machine tools.
Worm gears are cheaper than traditional gearboxes. They also have many benefits, including noise reduction. The output shaft of the worm gear reducer gearbox is almost 90 degrees from the motor input shaft, making it ideal for high-torque applications.
The worm gear reducer gearbox adopts an aluminum body, which is light in weight and high in operation efficiency. Additionally, they are available with hollow shafts and mounting flanges. In terms of initial cost, worm gear reducer gearboxes are cheaper than planetary gearboxes. In addition, they have better efficiency and longer service life.
Worm drives are also ideal for portable battery-powered lifting equipment. The high gear ratio of the worm gear ensures that it does not reverse drive. The worm gear has a spring-applied brake that holds the motor in place.
Planetary gearboxes are popular among industrial users. The efficiency of planetary gearboxes is important for practical applications.

pocket

The compact worm gear unit consists of a housing with an inner cavity. It has two side walls, one on either side of the front cover (13) and one on both sides of the rear cover (14). The front end cap is screwed onto the housing and the inner cavity is accessed through the rear end cap.
The compact worm gear unit can be configured to suit your application. They have many advantages, including saving space and increasing torque. The range includes single-envelope and double-envelope versions, available in a number of different power ratings. Additionally, they are IP65-rated, making them ideal for applications involving high radial or axial forces.
The compact worm reducer gearbox is a simple but effective worm drive. Its worm gear 16 meshes with the output shaft and rotates relatively stably. It also has a front-end cap and rear bearing. This enables the compact worm reducer gearbox to reduce vibration without damaging the output shaft.
Compact worm gear reducer gearboxes are ideal for many applications and offer high efficiency. The compact design means you can mount them on the motor’s flange or base. Its durable construction makes it ideal for a variety of industries. They are extremely durable and can handle high-pressure and washdown conditions. They also come standard with a synthetic shaft.

high efficiency

High-efficiency worm gear reducer gearboxes are ideal for applications that require precision, repeatability, and efficient performance. These reducer gearboxes are designed with state-of-the-art servo motor technology to provide tight integration and an angular backlash of less than two arc minutes. The reduction ratio can be lower if the application requires it.
Rising energy costs have led to an increased focus on the efficiency of drives. In response to this, manufacturers have increased the efficiency of worm gear reducer gearboxes through a number of technical improvements. By minimizing losses from rolling and sliding friction, worm gear reducer gearboxes are more efficient than their counterparts.
The high-efficiency worm reducer gearbox is simple in design and has the characteristics of a compact structure, high-speed ratio, low power consumption, and self-locking. Other advantages of these reducer gearboxes include low noise and long service life. Many also have built-in control systems that allow manual and remote adjustments. They also feature automatic shutdown protection and thermal protection.
High-efficiency worm reducer gearboxes can be used for mechanical acceleration. The input hypoid gear is usually made of steel, while the output hypoid gear is usually made of bronze. Bronze is a soft metal that is good at absorbing shock loads. However, bronze requires work hardening to achieve optimum hardness. For large worm gears, this process can take 300 to 550 hours.
worm reducer

low clearance

A low-clearance worm reducer gearbox is a device used to adjust the speed of a rotating shaft. It uses a worm gear consisting of two members. One worm is at one end of the shaft and the other is at the other end. Both worms are screwed into the synchronous drive structure.
Low clearance worm gear reducer gearboxes can be produced on conventional worm gear production lines without overlapping investments. These units are usually made of soft rubber. Also, they are relatively quiet in operation. These machines are designed so that they are suitable for use in elevators. The softer material in the worm gear also helps absorb shock loads.
The tooth profile of the worm gear is designed to change with the axial movement of the worm. Worms have thinner right teeth and thicker left teeth. As the worm moves to the right, its teeth mesh with the worm gear, reducing backlash.
There are many different types of worm gears. The design of gears depends on many factors, including backlash, thermal design, friction factors and lubrication. Worm gears are made of several different materials. Some different types of materials used in worm gears require special lubrication.

quieter

The quieter worm reducer gearbox is designed to reduce the noise level of the rotating gear motor. The device has more gear teeth in meshing contact with the gears, which helps it run more quietly. In addition to being quieter than other transmissions, it’s also less expensive than its counterparts.
Worm gearboxes can be used for different applications, but they are not as efficient as helical gearboxes. Worm reducer gearboxes are cheaper but less than 90% efficient. Higher gear ratios reduce efficiency, so worm gear reducer gearboxes are better suited for applications that require low-speed torque. The cost of buying a worm gearbox will depend on the horsepower and gear ratios required.
Worm reducer gearboxes are also more comfortable to use than planetary gearboxes. They don’t vibrate and heat up quickly, making them an excellent choice for low to medium horsepower applications. Worm gear reducer gearboxes can be upgraded to improve their performance by combining with other gear trains or gearboxes.
worm reducer

easy to replace

An easily replaceable worm gear reducer gearbox can save you a lot of money. A worm gear reducer gearbox is part of a chain drive and allows you to change gear ratios quickly and easily. Worm gear reducer gearboxes can be easily replaced in a number of ways. It’s a good idea to read the manufacturer’s manual before replacing a worm gear reducer gearbox. Make sure you have the instructions available so you can refer to them in the future.
Worm gear reducer gearboxes offer many advantages, including long service life and low noise. They are also designed with a 90-degree output shaft for easy installation. Another advantage of these gear reducer gearboxes is that they can be used with both solid and hollow output shafts. This means less maintenance and downtime.
Worm gear reducer gearboxes are widely used. Most gear manufacturers have large inventories. Worm gears also have uniform mounting dimensions. Dimensional consistency means you don’t have to worry about matching the shaft length and diameter to the worm gear. You can easily find a replacement worm gear reducer gearbox for your equipment.
When replacing the worm gear reducer gearbox, check the lubricating oil recommended by the machine. If not included, use original gear oil. Be sure to follow the manufacturer’s instructions carefully.
