The worm gear consists of a worm and a worm wheel. It is the simultaneous top offset of vertical energy transfer. Usually, the drive element is a worm. In buy to mix the wheel/worm into a worm equipment, it is essential to make sure that the heart length is equal and the transmission ratio is equal. Heart distances are offered from stock in modest measures amongst 17mm and 80mm. Every middle distance has several gear ratios. The extreme force worm equipment is appropriate for the production of worm gear drives with a shaft angle of 90°. Making use of a worm drive, very huge reduction ratios (up to one hundred:1) can be reached.
