Working principle of planetary reducer, structural breakdown, important advantages and products

working principle

It consists of an internal gear ring (A) tightly coupled to the gear box casing. There is a sun gear (B) driven by external power in the center of the ring gear. There is a set of three gears in between. The planetary gear set (C) on the pallet floats on the support of the output shaft, internal gear ring and sun gear; when the input side power drives the sun gear of the planetary reducer, it can drive the planet gear to rotate and follow the The trajectory of the internal gear ring revolves along the center, and the rotation of the star drives the output shaft connected to the tray to output power.

product

The planetary gear reducer has the characteristics of light weight, small size, large transmission ratio range, high efficiency, smooth operation, low noise and strong adaptability.Reducers are widely used in industrial sectors such as metallurgy, mining, hoisting and transportation, electric power, energy, construction materials, light industry, and transportation.

Product Description:

1. P series planetary gear reducer adopts modular design and can be changed and combined according to customer requirements.

2. The reducer adopts involute planetary gear transmission and rationally utilizes internal and external meshing and power splitting.

3. The box body is made of ductile iron, which greatly improves the rigidity and shock resistance of the box.

4. The gears are carburized and quenched to obtain a high-hardness and wear-resistant surface. After heat treatment, the gears are all ground, which reduces noise and improves the efficiency and service life of the entire machine.

5. The P series of planetary reducers have 9-34 specifications, and the planetary transmission stages include 2 and 3 levels.

Reduction ratio: 25~4000r/min (larger speed ratio can be achieved when combined with RX, R, and K series)

Output torque: up to 2600000Nm

Motor power: 0.4-12934kW
