The principle and characteristics of planetary reducer

To understand the principle of planetary reducer, we must first understand its structure.The planetary reducer is composed of body, planetary carrier, planetary gear, sun gear, stage gear, inner ring gear, output bearing, output shaft oil seal, input bearing, and input force.It consists of a shaft oil seal and various fixing screws.Among them, the planetary gear (combined in the planetary gear carrier), the sun gear stage gear and the ring gear are the four parts that are basically transmitted to the structure.Its transmission principle is:

1. The driving source directly starts the sun gear, and the sun gear drives the planetary gears combined on the planetary gear carrier to run.

2. The entire planetary gear system runs automatically and rotates along the outer ring gear, and the planetary gear carrier is connected to the output shaft for output to achieve acceleration.

3. It is necessary to accumulate a higher reduction ratio by adding multiple sets of gears and planetary gears.

The deceleration characteristics of the planetary reducer are:

1. High torque and shock resistance;

2. Small size and light weight;

3. High efficiency and low recoil.

4. Wide deceleration range and high precision.
