Worm gear is a mechanical component commonly used for rotating or transmitting motion and force. It is a type of gear with a special spiral tooth pattern, It is named after its shell that resembles a snail in appearance. Worm gears are usually used in conjunction with bevel gears (also known as worm gears) to convert rotational motion Direction, speed, and strength. The combination of worm gear and bevel gear can achieve a large reduction ratio, so it is often applied in mechanical transmission systems In equipment such as reducers, elevators, and conveyor belts.
