Functional characteristics of planetary gear reducer
A planetary gear reducer is a reducer composed of one or more sets of planetary gears, sun gears, internal ring gears, etc. The small gear in the middle of the figure is the sun gear, and the multiple self rotating gears (illustrated as 3) distributed on the inner ring gear and sun gear are the planetary gears.

A three-phase asynchronous motor, also known as an induction motor, is a motor with a simple structure, sturdy and durable, easy to use and maintain, and reliable operation. It is mainly composed of a stator and a rotor. At present, the vast majority of power equipment, such as machine tools, lifting equipment, transportation machinery, blowers, various pumps, as well as electric fans, medical equipment and other devices in daily life, are widely used. Three phase asynchronous motors need regular maintenance to ensure reliable operation.

A very common three-phase asynchronous motor
After the stator of a three-phase induction asynchronous motor is energized, a rotating magnetic field (magnet) is formed. Due to the induced electromotive force and short-circuit winding on the rotor, a rotating magnetic field is also generated. The rotating magnetic field of the rotor naturally follows the rotating magnetic field of the stator, and the two magnetic fields are relatively stationary. To apply force to the rotor, the rotor speed cannot be the same as the rotating magnetic field of the stator. Once it is the same, there will be no cutting electromotive force and no magnetic field.

Common Fault Analysis of Hard Gear Reducer (Four Series)
What are the reasons for pitting and peeling of gearbox gears Material, hardness, and defects. The material of the gear does not meet the requirements; The main factor affecting the contact fatigue strength of gears is the low hardness after heat treatment, which cannot guarantee the expected contact fatigue strength of gears. In addition, defects on the surface or inside of the teeth are also one of the reasons for insufficient contact fatigue strength. Poor gear accuracy. The precision of gear processing and assembly does not meet the requirements, such as poor meshing accuracy and motion accuracy. The center distance error of the shell of the circular arc gear is too large. The lubricating oil does not meet the requirements. The brand of lubricating oil
