The worm gear is composed of a worm and a worm wheel. It is the simultaneous peak offset of vertical electricity transfer. Usually, the drive component is a worm. In order to merge the wheel/worm into a worm gear, it is required to make sure that the centre distance is equal and the transmission ratio is equal. Centre distances are obtainable from stock in little steps among 17mm and 80mm. Each and every center distance has several equipment ratios. The extreme stress worm equipment is ideal for the manufacturing of worm equipment drives with a shaft angle of 90°. Employing a worm push, quite huge reduction ratios (up to one hundred:1) can be attained.
