Functions and types of sew reducer

Sew reducer is an important machine in the field of industrial control. It is generally used for transmission equipment with low speed and high torque. It is a power transmission mechanism. It uses the speed converter of the gear to decelerate the rotation of the motor to the desired rotation and obtain a larger torque.

Sew reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator. It is a relatively precise machine. The motor, internal combustion engine or other high-speed power can be decelerated by meshing the gear with few teeth on the input shaft of the reducer with the large gear on the output shaft.

There are many kinds of reducers, which can be divided into gear reducers, worm reducers and planetary gear reducers according to the transmission type; According to different transmission stages, it can be divided into single-stage and multi-stage reducers; According to the gear shape, it can be divided into cylindrical gear reducer, conical gear reducer and conical cylindrical gear reducer; According to the arrangement of transmission, it can be divided into deployable reducer, shunt reducer and coaxial reducer.

1、 Function of sew reducer

At the same time, the speed reduces the inertia of the load, which is the square of the reduction ratio. As you can see, most motors have an inertia value. （2） Reduce the speed and increase the output torque at the same time. The torque output ratio shall be multiplied by the motor output by the reduction ratio, but pay attention not to exceed the rated torque of the reducer.

2、 Type of sew reducer

General sew reducers include helical gear reducers, including parallel shaft helical gear reducers, worm gear reducers, bevel gear reducers, etc., planetary gear reducers, cycloidal needle gear reducers, worm gear reducers, planetary friction mechanical gearless reducers, etc.

Sew reducer is generally used for transmission equipment with low speed and large torque The internal combustion engine or other high-speed power can achieve the purpose of reducing speed by meshing the large gear on the output shaft with the gear with a small number of teeth on the input shaft of the reducer. Ordinary reducers also have several pairs of gears with the same principle to achieve ideal reduction results. The ratio of the number of teeth of large and small gears is the transmission ratio.
