The effectiveness of a worm equipment transmission depends to a big extent on the helix angle of the worm. Multi-threaded worms and gears with higher helix angles have established to be twenty five% to 50% much more successful than single-threaded worms. The sliding action of the worm meshing with or meshing with the worm equipment results in substantial friction and reduction of effectiveness when compared to other varieties of gears. Boost efficiency with hardened and ground worm switch bronze worm gears.
