The offered worm wheel is one of the two parts of a worm gear. These one-way gears are used to prevent energy from flowing backward into a system and to turn the output power of a gearing system. The worm gears have an interesting feature that other gear sets dont: the worm can turn the gear easily, but the gear cant. The gear mechanism is often used to transfer the motion and power between two staggered shafts. Worm Wheel is made for industrial uses.
