Working principle:
An internal gear ring (A) is tightly coupled to the gear box casing. There is a sun gear (B) driven by external power in the center of the ring gear. , between the two there is a set of planetary gear sets (C) composed of three gears equally divided on the pallet. This set of planetary gears floats in the middle relying on the output shaft, internal gear ring and sun gear support;
When the input side power of the planetary reducer drives the sun gear, it can drive the planetary gear to rotate and revolve along the center following the trajectory of the internal gear ring. The rotation of the planetary gear drives the output shaft connected to the pallet to output power.
Extended information
The internal gear of the planetary reducer is made of 20CrMnTi carburizing, quenching and grinding. It has small size, light weight, high load-bearing capacity, long service life, smooth operation, low noise, It has the characteristics of large output torque, large speed ratio, high efficiency and safe performance. It has the unique characteristics of power splitting and multi-tooth meshing. It is a new type of reducer with wide versatility. The maximum input power can reach 104kW.
It is suitable for industrial sectors such as lifting and transportation, engineering machinery, metallurgy, mining, petrochemicals, construction machinery, light industry and textiles, medical equipment, instrumentation, automobiles, ships, weapons and aerospace. Varieties: WGN fixed shaft transmission reducer, WN mother and daughter gear transmission reducer, elastic load-equalizing and small tooth difference reducer.
