about worm reducer
A worm gear reducer is a type of reduction gear that is used to convert high motor speed input into lower speed output while also maintaining high torque. The worm producer consists of a gear in the form of a screw meshed into the machine which outputs in the right angle orientation. The worm reducer is mostly made of bronze with steel or stainless steel worm. The size of the worm reducer is very small and sleek compared to other gear reducers which makes it very handy for rated motor speed and space problems.

Uses of Worm Reducer?

The worm reducers are applied in fields like tuning instruments, elevators, escalators, conveyor belts, medical equipment, power transmission systems, and security gates to name a few.
