High-speed power devices such as electric motors and internal combustion engines require a process of speed reduction and torque increase to the working end of the power device. The reducer is the power transmission mechanism that realizes this process.
Planetary reducer is an industrial product with a wide range of uses. The reducer is small in size, light in weight, high in load capacity, long in service life, stable in operation, and low in noise. It has the characteristics of power splitting and multi-tooth meshing. Larger input power can reach 104kW.
Suitable for industrial sectors such as lifting and transportation, construction machinery, metallurgy, mining, petrochemical, construction machinery, light industry and textiles, medical equipment, instrumentation, automobiles, ships, weapons, aerospace and other industrial sectors. , WN sub-and-mother gear transmission reducer, elastic uniform load and small tooth difference reducer.
Planetary reducer is a novel reducer with wide versatility. The internal gear adopts 20CvMnT carburizing, quenching and tooth grinding. The whole machine has the characteristics of small structure size, large output torque, high speed ratio, high efficiency, and safe and reliable performance.

Number of stages: the number of sets of planetary gears. Because one set of planetary gears cannot meet the larger transmission ratio, sometimes 2 or 3 sets are needed to meet the requirement of supporting a 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.
Planetary reducer
Return clearance: Fix the output end and rotate the input end clockwise and counterclockwise to make the input end produce rated torque +-2% torque, there is a slight angular displacement at the input end of the reducer, and this angular displacement is the return clearance. The unit is "cent", which is one-sixtieth of a degree, which is also called backlash.

Planetary reducer structure
The main transmission structure of the planetary reducer is: planetary gear, sun gear, and outer ring gear.
Because of the structure of the planetary reducer, the single-stage reduction is as small as 3, and the larger generally does not exceed 10. The common reduction ratios are: 3, 4, 5, 6, 8, 10, and the number of reducers generally does not exceed 3, but there are Some customized gearboxes with large reduction ratios have 4-stage reduction.
