what is planetary gear reducer
Jul 28, 2018

The principle of the planetary reducer is a power transmission mechanism that uses a gear speed converter to decelerate the number of revolutions of the motor to a desired number of revolutions and obtain a mechanism of a large torque. A gear with a small number of teeth on the planetary reducer drive shaft meshes with the large gear on the output shaft to achieve the purpose of deceleration. Ordinary speed reducers will also have several pairs of gears of the same principle to achieve the desired deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.

The planetary reducer is a versatile industrial product that is comparable in performance to other military grade reducer products, but has the price of industrial grade products and is used in a wide range of industrial applications. P series planetary reducer reduction ratio: 25 ~ 4000r / min (combined with R, K series can achieve greater speed ratio), output torque: up to 2600000Nm, motor power: 0.4-12934kW, product installation form: foot Installation, flange mounting, torsion arm mounting, shaft output: solid shaft, involute spline solid shaft, etc. Planetary reducer is widely used in slewing mechanism, roller press, bucket turbine, baffle conveyor, separator, Aerator, travel drive reducer, steel belt rotary mill, rotary kiln, etc. P-Series planetary gear reducers are available in more than 27 sizes, including 2 or 3 planetary gears that can be combined with different types of primary gears. The primary gear can be a helical gear, a bevel gear or a combination of helical and straight teeth. High-quality machining accuracy and finite element analysis of the planetary gear cage optimize the load distribution on the surface of the planetary gears and other contact parts. The P-Series planetary gear reducers are modular in design and can be combined according to customer requirements. Involute planetary gear transmission, reasonable use of internal and external meshing, power splitting, the box body is made of ductile iron, which greatly improves the rigidity and shock resistance of the box. The gears are treated with carburizing and quenching to obtain a high-hard wear-resistant surface. After the gear is heat treated, all the teeth are ground, which reduces the noise and improves the efficiency and service life of the whole machine. Therefore, it has the characteristics of light weight, small volume, large transmission ratio range, high efficiency, stable operation, low noise and strong adaptability.
