The development history of reducer industry in China has been 40 years, and it has been widely used in various fields. The emergence of reducer has made a great breakthrough in the national economy and national defense industry. In the reducer family, planetary reducers are widely used in precision machine tools, automatic cutting equipment, metallurgical equipment, printing equipment, injection molding machine equipment, packaging equipment and other neighborhoods because of their beautiful appearance, accurate positioning, economy and practicality, high precision and large bearing capacity.
Next, let's follow hefuyuan Xiaobian to understand what is a planetary reducer?
Overview of planetary reducer:
Planetary reducer is a kind of widely used deceleration equipment. The accuracy of planetary reducer is very high. On the premise of ensuring precision transmission, planetary reducer is mainly used to reduce speed, increase torque and reduce the moment of inertia ratio of load / motor. Planetary reducer is also called servo reducer or servo planetary reducer.
The planetary reducer adopts involute planetary gear transmission, makes rational use of internal and external meshing and power diversion, and the box body adopts nodular cast iron, which greatly improves the rigidity and seismic resistance of the box body; The gears are carburized and quenched to obtain a high hard and wear-resistant surface. All the gears are ground after heat treatment, which reduces the noise and improves the efficiency and service life of the whole machine; There are 2 and 3 stages of planetary transmission stages of planetary reducer, which is the most commonly used stage.
The main transmission structure of planetary reducer is: planetary gear, sun gear, internal gear ring, drive motor and transmission shaft.
From the appearance, the planetary reducer can be divided into three sections: input section, deceleration section and output section.
Input section: the input section refers to the end connected with the motor. Including input shaft hole and input flange
Reduction section: the reduction section refers to the core section of the reducer. From the outside, it looks like a box. In fact, it contains many core components, such as planetary gear, sun gear and inner ring gear.
Output section: output section refers to the end connected with the equipment, including output shaft and output flange.
Advantages of planetary reducer transmission:
It has the characteristics of small volume, light weight, high bearing capacity, long service life, stable operation, low noise, large output torque, large speed ratio, high efficiency and safe performance. It has the characteristics of power split and multi tooth meshing. The transmission efficiency of planetary reducer is generally more than 90%, which can reach more than 95%. It is widely used.
Purpose of planetary reducer:
Planetary reducer is widely used in spring machinery, manipulator, textile machinery, machine tool manufacturing, precision machining machine tools, aerospace industry, smart home, automobile manufacturing, shipbuilding industry, semiconductor equipment, printing machinery, food packaging, automation industry, industrial robot, medical inspection, precision testing instruments and automatic high-precision electromechanical products.
