The efficiency of a worm gear transmission depends to a big extent on the helix angle of the worm. Multi-threaded worms and gears with higher helix angles have verified to be twenty five% to fifty% far more efficient than solitary-threaded worms. The sliding action of the worm meshing with or meshing with the worm gear outcomes in significant friction and decline of effectiveness compared to other kinds of gears. Enhance performance with hardened and floor worm swap bronze worm gears.
