Reducer definition and working principle

The speed reducer is a power transmission mechanism that utilizes a gear speed converter to decelerate the number of revolutions of the motor (motor) to the desired number of revolutions, and to obtain a mechanism with greater torque. In the current mechanism for transmitting power and motion, the application range of the speed reducer is quite extensive. It can be seen in almost all kinds of mechanical transmission systems, from ships, automobiles, locomotives in vehicles, heavy machinery used in construction, processing equipment used in machinery industry, and automated production equipment to common everyday life. Household appliances, watches, etc. Its application can see the application of the reducer from the transmission of large power, to the small load, accurate angle transmission, and in the industrial application, the reducer has the functions of deceleration and increasing torque. Therefore, it is widely used in speed and torque conversion equipment.

The main functions of the reducer are:

1) Reduce the speed and increase the output torque at the same time. The ratio of the torque output is the output/deceleration ratio of the motor output, but be careful not to exceed the rated torque of the reducer.

2) Deceleration reduces the load inertia at the same time, and the inertia reduction is the square of the reduction ratio. We can see that the general motor has an inertia value.

The working principle of reducer

Reducer is generally used for low speed high torque transmission equipment, the motor, internal combustion engine or other high-speed power through the reducer on the input shaft with a small number of gear meshing gear shaft on the output shaft to achieve the purpose of deceleration, ordinary Reducer will also have several pairs of the same principle gear to achieve the ideal deceleration effect, the ratio of the number of teeth of the large and small gear is the transmission ratio.
