The performance of a worm equipment transmission is dependent to a massive extent on the helix angle of the worm. Multi-threaded worms and gears with greater helix angles have verified to be 25% to 50% more effective than single-threaded worms. The sliding action of the worm meshing with or meshing with the worm gear final results in considerable friction and loss of performance when compared to other sorts of gears. Enhance performance with hardened and ground worm swap bronze worm gears.
