The travel element is a worm. In purchase to merge the wheel/worm into a worm equipment, it need to be ensured that the center length is equivalent and the transmission ratio is equivalent. Middle distances are available from stock in modest measures amongst 17mm and 80mm. Each centre distance has numerous gear ratios. Ep worm gears are suited for the generation of worm drives with a shaft angle of 90°. Employing a worm push, really large reduction ratios (up to 100:1) can be achieved.
