Ep Gear’s worm gears use proper-angle (90°) non-intersecting shafts to supply an successful solution for power transmission purposes requiring substantial reduction ratios in confined areas. When properly applied, worm gears provide the smoothest and quietest sort of transmission. Since the efficiency of a worm travel relies upon on the guide angle and the number of stars on the worm – given that efficiency is always the objective, this ratio ought to be held as minimal as possible. To work correctly, the worm and worm equipment used together should have the same diameter, pitch and thread.
