Planetary reducer is a widely used industrial product, which can reduce the speed of motor and increase the output torque at the same time. Planetary reducer can be used as a supporting part in hoisting, excavation, transportation, construction and other industries. Let's talk about Dongyu hydraulic.

Because a set of planetary gears cannot meet the larger transmission ratio, sometimes two or three sets are needed to meet the user's requirements for larger transmission ratio Due to the increase in the number of planetary gears, the length of the 2-stage or 3-stage reducer will increase and the efficiency will decrease. Return clearance: when the output end is fixed and the input end rotates clockwise and counterclockwise to produce the rated torque + - 2% torque at the input end, there is a small angular displacement at the input end of the reducer, which is the return clearance The unit is "minute", which is one sixtieth of a degree It is also called dorsal gap. With the continuous development of the reducer industry, more and more enterprises apply to the reducer. The planetary reducer is an industrial product. The planetary reducer is a transmission mechanism. Its structure is closely combined with an internal gear ring on the gearbox shell. There is a sun gear driven by external dynamic force in the center of the ring gear. Between them, there is a set of planetary gear sets composed of three gears equally on the tray, The planetary gears are supported by the output shaft, inner gear ring and sun gear during floating; When the power on the input side drives the sun gear, it can drive the planetary gear to rotate and revolve along the center according to the track of the inner gear ring. The rotation of the planet drives the output shaft connected to the tray to output power. Using the speed converter of gear, the rotation number of motor (motor) is reduced to the required rotation number, and a mechanism with large torque is obtained. Among the reducer mechanisms used to transmit power and motion, the planetary reducer is a precision reducer, and the reduction ratio can be accurate to 0.1-0.5 R / min.

The internal gear of planetary reducer adopts 20CrMnTi carburizing, quenching and grinding, which 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 shunting and multi tooth meshing. It is a new type of reducer with wide universality. The input power can reach 104kw. It is applicable to WGN fixed shaft transmission reducer, WN sub parent gear transmission reducer and elastic load less tooth difference reducer of new planetary Series in industrial departments such as lifting and transportation, engineering machinery, metallurgy, mining, petrochemical industry, construction machinery, light industry and textile, medical equipment, instruments and meters, automobile, ship, weapon and aerospace.
