Working principle of reducer

To put it simply, it is to use all levels of gear transmission to achieve the purpose of deceleration. The reducer is composed of gear pairs at all levels. For example, a small gear can be used to drive a large gear to achieve a certain purpose of deceleration. The structure can greatly reduce the speed.

The reducer is generally used for low-speed and high-torque transmission equipment. The power of the electric motor, internal combustion engine or other high-speed running is achieved by the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft. The reducer will also have several pairs of gears with the same principle to achieve the desired deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.

The reducer is a kind of power transmission mechanism. The ground boundary mold uses the speed converter of the gear to reduce the number of revolutions of the motor to the required number of revolutions and obtain a mechanism with a large torque.

The role of the reducer

1. Reduce the speed and increase the output torque at the same time. The torque output ratio is the motor output multiplied by the reduction ratio, but it must be noted that the rated torque of the reducer cannot be exceeded.

2. Deceleration reduces the inertia of the load at the same time, and the reduction of inertia is the square of the reduction ratio.You can see that the general motor has an inertia value.Types of reducers The general reducers include helical gear reducers (including parallel shaft helical gear reducers, worm gear reducers, bevel gear reducers, etc.), planetary gear reducers, cycloidal pinwheel reducers, and worm gear reducers. , Planetary friction type mechanical CVT and so on.
