Knowledge about speed-adjustable reduction motors

Date:2023-12-04   Author:XINDA MOTOR

The speed-regulating reduction motor is an independent closed transmission device between the prime mover and the working machine. It is used to reduce the speed and increase the torque to meet the work needs. It is also used to increase the speed in some occasions, which is called a speed increaser. 


When selecting, the appropriate speed regulation should be selected based on the selection conditions of the working machine, technical parameters, performance of the power machine, economy and other factors, and comparing the outer dimensions, transmission efficiency, load-bearing capacity, quality, price, etc. of different types and varieties of reducers. Geared motor.




It is mainly composed of transmission parts gears or worms , shafts, bearings, boxes and accessories.


Speed-adjustable reduction motor classification:


There are many categories, varieties, and types of reducers. Currently, there are more than 40 types of reducers that have been formulated as industry (national) standards The categories of reducers are divided according to the gear tooth shape and tooth profile curve used; the varieties of reducers are reducers with different structures designed according to the needs of use; the types of reducers are based on the tooth surface on the basis of the basic structure. Reducers with different characteristics are designed based on factors such as hardness, transmission series, output shaft type, assembly type, installation type, and connection type.


Load classification:


The load state of the working machine connected to the reducer is relatively complex and has a great impact on the reducer. It is an important factor in the selection and calculation of the reducer. The load state of the reducer is the load state of the working machine (slave machine), which is usually divided into three types. kind:


) Uniform load ;


) Moderate impact load ;


) Strong impact load.


installation method:


Correct installation, use and maintenance of speed-adjustable reduction motors are important links to ensure the normal operation of mechanical equipment. Therefore, when you install it, please be sure to strictly follow the installation and use related matters below and assemble and use it carefully.


The first step: confirm whether the motor and reducer are intact before installation, and strictly check whether the dimensions of the parts connecting the motor and the reducer match. Here are the dimensions of the motor's positioning boss, input shaft and reducer groove, etc. Fit tolerances.


Step 2: Try to unscrew the screw on the dust-proof hole on the outside of the reducer flange, adjust the clamping ring to align the side hole with the dust-proof hole, insert the inner hexagon and tighten it. After that, remove the motor shaft key.


The third step: Naturally connect the motor and reducer. When connecting, it must be ensured that the concentricity of the reducer output shaft and the motor input shaft are consistent, and that the outer flanges of the two are parallel. If the concentricity is inconsistent, it will cause the motor shaft to break or the speed reduction motor gear to wear.
