The performance of a worm equipment transmission relies upon to a massive extent on the helix angle of the worm. Multi-threaded worms and gears with increased helix angles have established to be 25% to 50% far more efficient than single-threaded worms. The sliding motion of the worm meshing with or meshing with the worm gear final results in substantial friction and loss of efficiency in contrast to other varieties of gears. Boost efficiency with hardened and floor worm switch bronze worm gears.
