The efficiency of a worm gear transmission relies upon to a huge extent on the helix angle of the worm. Multi-threaded worms and gears with greater helix angles have established to be twenty five% to 50% far more successful than single-threaded worms. The sliding motion of the worm meshing with or meshing with the worm equipment outcomes in considerable friction and decline of efficiency when compared to other varieties of gears. Increase performance with hardened and floor worm switch bronze worm gears.
