The travel component is a worm. In order to blend the wheel/worm into a worm equipment, it must be ensured that the centre length is equal and the transmission ratio is equivalent. Middle distances are offered from stock in tiny actions amongst 17mm and 80mm. Every center length has numerous gear ratios. Ep worm gears are suited for the creation of worm drives with a shaft angle of 90°. Employing a worm push, very huge reduction ratios (up to a hundred:1) can be attained.
