The travel factor is a worm. In buy to blend the wheel/worm into a worm gear, it must be ensured that the heart distance is equal and the transmission ratio is equal. Middle distances are accessible from stock in modest steps in between 17mm and 80mm. Each and every middle distance has a number of equipment ratios. Ep worm gears are suitable for the manufacturing of worm drives with a shaft angle of 90°. Making use of a worm drive, very large reduction ratios (up to 100:1) can be reached.
