The efficiency of a worm equipment transmission relies upon to a large extent on the helix angle of the worm. Multi-threaded worms and gears with increased helix angles have verified to be twenty five% to fifty% a lot more successful than solitary-threaded worms. The sliding motion of the worm meshing with or meshing with the worm gear final results in significant friction and reduction of efficiency when compared to other kinds of gears. Enhance performance with hardened and ground worm swap bronze worm gears.
