The worm equipment consists of a worm and a worm wheel. It is the simultaneous height offset of vertical power transfer. Normally, the drive aspect is a worm. In order to merge the wheel/worm into a worm gear, it is necessary to make sure that the heart length is equivalent and the transmission ratio is equal. Centre distances are offered from stock in modest steps between 17mm and 80mm. Each and every center length has a number of gear ratios. The severe strain worm gear is suitable for the generation of worm equipment drives with a shaft angle of 90°. Using a worm travel, quite huge reduction ratios (up to a hundred:1) can be accomplished.
