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 increased helix angles have established to be 25% to fifty% far 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 when compared to other sorts of gears. Enhance effectiveness with hardened and ground worm swap bronze worm gears.
