A worm gear reducer is a transmission device that uses the meshing between a worm wheel and a worm to achieve power transmission and deceleration and torque increase. It drives the worm wheel to rotate through the rotation of the worm, thereby converting the input high speed into the output low speed.
Worm gear reducers have the characteristics of compact structure, large reduction ratio, smooth operation, low noise and self-locking function. It can achieve a large reduction ratio in a small space, and its self-locking function can prevent the load from falling freely when the power is off or the power is lost, increasing the safety of operation. However, the transmission efficiency of worm gear reducers is relatively low, generally between 50%-70%.Worm gear reducers are widely used in many industries.
