The effectiveness of a worm gear transmission relies upon to a big extent on the helix angle of the worm. Multi-threaded worms and gears with greater helix angles have confirmed to be 25% to fifty% far more effective than one-threaded worms. The sliding motion of the worm meshing with or meshing with the worm equipment final results in significant friction and loss of efficiency in comparison to other kinds of gears. Improve performance with hardened and ground worm switch bronze worm gears.
