The purpose and function of the reducer

Familiar withReducerEveryone knows that the reducer is a power transmission mechanism that uses the speed converter of the gear to decelerate the number of revolutions of the motor to the required number of revolutions and obtain a larger torque mechanism, so the purpose and function of the reducer Which are there?

  To put it simply, it is to use all levels of gear transmission to achieve the purpose of speed reduction, and the reducer is composed of gear pairs at all levels.For example, using a small gear to drive a large gear can achieve a certain purpose of deceleration, and then using a multi-stage structure can greatly reduce the speed.The reducer is generally used for low-speed and high-torque transmission equipment, turning the motor.The internal combustion engine or other power running at high speed achieves the purpose of deceleration through the gears with a small number of teeth on the input shaft of the reducer meshing with the large gears on the output shaft to achieve the purpose of deceleration. Ordinary reducers will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the big and small gears is the transmission ratio.Among them, the role of the reducer has the following two points.

  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, planetary gear reducers, cycloidal pinwheel reducers, worm gear reducers, planetary friction type mechanical stepless transmissions and so on.

  ReducerGenerally used for low-speed high-torque transmission equipment, the motor.Therefore, an ordinary reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.
