Ep Gear’s worm gears use correct-angle (90°) non-intersecting shafts to give an efficient remedy for electrical power transmission purposes requiring higher reduction ratios in confined spaces. When effectively utilized, worm gears offer the smoothest and quietest kind of transmission. Since the effectiveness of a worm drive depends on the lead angle and the amount of stars on the worm – considering that efficiency is always the goal, this ratio should be held as reduced as attainable. To perform appropriately, the worm and worm gear utilized with each other need to have the same diameter, pitch and thread.
