The performance of a worm equipment transmission is dependent to a huge extent on the helix angle of the worm. Multi-threaded worms and gears with larger helix angles have verified to be twenty five% to fifty% more effective than solitary-threaded worms. The sliding motion of the worm meshing with or meshing with the worm gear benefits in considerable friction and decline of efficiency when compared to other types of gears. Enhance efficiency with hardened and floor worm change bronze worm gears.
