A worm 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 gearbox 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.

The basic benefit of the worm reducer is that it produces an output of ninety degrees to the input with higher torque and lower speed. In addition to the benefits of high-speed reduction and torque multiplication, the worm gearbox also provides for shock absorption, quiet operation, smaller size, and the adjustable mounting position. This makes the worm reducer the best quality reducer for heavy applications.
