Overview of planetary reducer:
Planetary reducer is a widely used reduction equipment. The precision of planetary reducer is very high. Under the premise of ensuring precise transmission, planetary reducer mainly It is used to reduce the speed, increase the torque and reduce the load/motor inertia ratio. Planetary reducer is also called servo reducer or servo planetary reducer.
The planetary reducer adopts involute planetary gear transmission, rationally utilizing internal and external meshing and power splitting. The box is made of ductile iron, which greatly improves the rigidity and shock resistance of the box; the gears are all made of permeable The carbon is quenched to obtain a high-hard wear-resistant surface. After the heat treatment of the gears, all the teeth are ground, which reduces the noise and improves the efficiency and service life of the whole machine. The planetary transmission stages of the planetary reducer are 2 and 3, which are the most commonly used of series.
The main transmission structure of the planetary reducer is: planetary gear, sun gear, internal ring gear, drive motor, and transmission shaft.
The appearance of the planetary reducer can be divided into three sections: input section, reduction section and output section.
Input section: The input section refers to the end connected to the motor. Including input shaft hole, input flange
Reduction section: The reduction section refers to the core section of the reducer. It looks like a box from the outside. In fact, it contains many core components, such as planetary gears, sun Gears, internal ring gears.
Output section: The output section refers to the end connected to the equipment, including the output shaft and output flange.
Planetary reducer transmission advantages:
Small size, light weight, high carrying capacity, long service life, smooth operation, low noise, large output torque, large speed ratio and high efficiency , performance and safety features. It has the unique characteristics of power splitting and multi-tooth meshing. The transmission efficiency of planetary reducer is generally above 90%, can reach above 95%, and is widely used.
Use of planetary reducer:
Planetary reducer is widely used in spring machinery, manipulators, textile machines, machine tool manufacturing fields, precision processing machine tools, aerospace industry, smart home, and automobile manufacturing. , shipbuilding industry, semiconductor equipment, printing machinery, food packaging, automation industry, industrial robots, medical inspection, precision testing instruments and automated high-precision electromechanical product industries.
