The worm equipment is composed of a worm and a worm wheel. It is the simultaneous height offset of vertical electrical power transfer. Typically, the drive component is a worm. In order to combine the wheel/worm into a worm equipment, it is needed to guarantee that the center length is equivalent and the transmission ratio is equal. Centre distances are available from stock in little actions in between 17mm and 80mm. Every centre distance has several gear ratios. The severe strain worm gear is ideal for the creation of worm gear drives with a shaft angle of 90°. Using a worm push, extremely big reduction ratios (up to a hundred:1) can be reached.
