The drive factor is a worm. In buy to combine the wheel/worm into a worm gear, it have to be ensured that the center length is equivalent and the transmission ratio is equal. Centre distances are available from stock in small methods amongst 17mm and 80mm. Every single middle distance has multiple gear ratios. Ep worm gears are suited for the creation of worm drives with a shaft angle of 90°. Employing a worm travel, extremely large reduction ratios (up to 100:1) can be reached.
