The reducer industry has been developing in China for many years and has been widely used in various fields. The emergence of the reducer has made great breakthroughs in the national economy and defense industry. In the reducer family,planetary reducerWith its beautiful appearance, accurate positioning, economical and practical, high precision, large volume and other advantages, it is widely used in precision machine tools, automatic cutting equipment, metallurgical equipment, printing equipment, injection molding machine equipment, packaging equipment and other neighborhoods. Next, let's take a look at what is a planetary reducer?
Overview of planetary reducer:
Planetary reducer is a widely used deceleration device with very high accuracy. Under the premise of ensuring the transmission accuracy, the planetary reducer is mainly used to reduce the speed, increase the torque, and reduce the load/motor moment of inertia ratio. Planetary reducer is also called servo reducer or servo planetary reducer.
planetary reducerInvolute planetary gear transmission, rational use of internal and external meshing and power distribution, the box body uses ductile iron, greatly improving the rigidity and shock resistance of the box body; gears are carburized and quenched to obtain high hardness and wear-resistant surface. All gears are heat-treated and ground, which reduces noise and improves the efficiency and service life of the whole machine. The planetary transmission stage of the planetary reducer has 2 and 3 stages, which are commonly used stages.
The main transmission structure of the planetary reducer is: planetary gear, sun gear, ring gear, drive motor, drive shaft.
planetary reducerFrom the appearance can be divided into three segments: input segment, deceleration segment and output segment.
Input section: The input section refers to the end connected with the motor, including the input shaft hole and the input flange.
Reduction section: The reduction section refers to the core part of the reducer. It looks like a box from the outside, but it actually contains many core components, such as planetary gears, sun gears, and inner ring gears.
Output segment: The output segment refers to the end connected to the device, including the output shaft and the output flange.
Planetary reducer transmission advantages:
Small size, light weight, high carrying capacity, long service life, stable operation, low noise, large output torque, large speed ratio, high efficiency, safety and other characteristics, with power split and multi-tooth meshing characteristics. The transmission efficiency of the planetary reducer is generally above 90%, which can reach more than 95%, and is widely used.
planetary reducerUse:
Planetary reducers are widely used in spring machinery, manipulators, textile machinery, machine tools, precision machining machine tools, aerospace industry, smart home, automobile manufacturing, shipbuilding industry, semiconductor equipment, printing machinery, food packaging, automation industry, industrial robots, medical testing, Precision testing instruments and automated high-precision electromechanical products industry.
