The performance of a worm equipment transmission depends to a large extent on the helix angle of the worm. Multi-threaded worms and gears with higher helix angles have established to be 25% to 50% much more efficient than solitary-threaded worms. The sliding motion of the worm meshing with or meshing with the worm equipment final results in substantial friction and reduction of efficiency compared to other varieties of gears. Enhance performance with hardened and floor worm swap bronze worm gears.
