The reducer is actually a power transmission mechanism, which does not generate power by itself. Its function is to use the gear size difference and speed converter to reduce the rotation number of the motor (motor) to the desired number of rotations, and obtain a comparison High torque mechanism. Is it possible to adjust the speed of the motor? However, it is not. The motor is directly connected to the equipment. When the equipment is running, the load of the motor is particularly large, and the damage to the motor is also very large. However, it is different through the reducer. For example, the reduction ratio is 100. Reducer, the speed ratio of the speed reducer = input speed / output speed, if the speed ratio is 100, the output torque is about 100 times the input torque. (The speed decreases and the torque increases) The load on the motor when the machine is running is only one percent. Moreover, if the reducer is broken, it only needs to replace the lower gear, and the cost is much lower than that of the motor.
The speed reducer is also a speed changer, but usually the speed changer is used to reduce the speed, which is habitually called the speed reducer; the usual speed reducer has a fixed transmission ratio, and it is also adjustable, but it is usually graded adjustment. What everyone can easily think of is that there is an adjustable reducer on the vehicle, so the vehicle has many gears. The gasoline engine (diesel engine) is the same as the motor. The speed of the accelerator can be changed, but the scope of change is not large.
The reducer is a relatively precise machine, and the purpose of using it is to reduce the speed and increase the torque. It has a wide variety of models, and different types have different uses. According to the transmission type, it can be divided into gear reducer, worm gear reducer and planetary gear reducer; according to the difference of transmission stages, it can be divided into single-stage and multi-stage reducer.
In the current mechanism used to transmit power and motion, the application scope of the reducer is quite extensive. The application of the reducer can be seen from the transmission of large power to the transmission of small loads and precise angle transmission. In industrial applications, the reducer has the function of reducing speed and increasing torque.
The main functions of the reducer are:
1) Reduce the speed and increase the output torque at the same time. The torque output ratio is multiplied by the motor output multiplied by the reduction ratio, but special attention should be paid not to exceed the rated torque of the reducer
2) Deceleration reduces the inertia of the load at the same time.
