The performance of a worm gear transmission depends to a massive extent on the helix angle of the worm. Multi-threaded worms and gears with greater helix angles have proven to be 25% to 50% much more productive than single-threaded worms. The sliding action of the worm meshing with or meshing with the worm gear results in substantial friction and loss of performance in comparison to other varieties of gears. Improve performance with hardened and ground worm swap bronze worm gears.
