Product Description Product DescriptionHigh Torque Precision Swing Planetary Reducer Redunction Gearbox for Excavator Transmission Gearbox A planetary gearbox, also known as an epicyclic gearbox or a planetary gear train, is a type of gear system used in various applications. It is a precision-engineered power transmission component designed for demanding industrial applications. Featuring a compact, robust structure and high torque density, it ensures reliable performance in machinery, automation systems, heavy equipment, and more. The planetary gear system achieves efficient power transmission and speed regulation through the precise coordination of the sun gear, planet gears, planet carrier, and ring gear. Each component plays a distinct role, collectively ensuring complex motion conversion within a compact space. This design not only enhances mechanical efficiency but also provides flexible solutions for various application scenarios.

This design not only enhances mechanical efficiency but also provides flexible solutions for various application scenarios.Product Constructions The planet carrier is the supporting structure of the planetary gear system, responsible for holding the planet gears and coordinating their motion. It converts the composite motion of the planet gears into a unified output, typically connected to the output shaft.In many designs, the planet carrier serves as the power output after speed reduction, playing a critical role in torque transmission. The ring gear is an internally toothed gear, usually fixed to the system's housing, though it can also be a movable component in certain designs.By meshing with the planet gears, the ring gear constrains their motion path, enabling the system's speed reduction function. Its structural design directly impacts the system's transmission efficiency and output characteristics. Planet gears typically consist of 3 to 4 small gears, evenly distributed around the sun gear. These gears mesh simultaneously with both the sun gear and the ring gear, creating a composite motion of both rotation on their own axes and revolution around the sun gear.This unique motion is key to the planetary gear system's ability to achieve speed reduction or increase. The planet gears are fixed by the planet carrier, ensuring stability and coordination in their motion.The sun gear is located at the center of the planetary gear system, directly connected to the input shaft, serving as the primary power input point.As the core driving component, the sun gear rotates to drive the surrounding planet gears. Its compact and efficient design ensures smooth power transmission to other parts of the system.Core Features & AdvantagesHigh Power Density: Transmits very high torque within an extremely compact space, resulting in a highly integrated structure.High Transmission Efficiency: The load is shared simultaneously by multiple planet gears, minimizing gear meshing friction losses and achieving transmission efficiency typically exceeding 97%. High Precision and Rigidity: The symmetrically distributed planet gears ensure balanced force distribution, reducing vibration and wear while providing high transmission accuracy and low backlash.Wide Reduction Ratio Range: A single stage can provide a high reduction ratio, and multi-stage nested combinations can achieve extremely large overall reduction ratios.Application ScenariosIndustrial Robots: Robot joints (RV reducers often utilize a precision planetary gear structure), requiring high precision, high rigidity, and compact size.Aerospace: Aircraft wing surface adjustment, helicopter transmission systems, demanding extreme reliability and lightweight design.New Energy Vehicles: Mounted on the drive motor as the main reducer, converting the motor's high speed into the high torque required by the wheels.Precision Machine Tools: Feed systems requiring high precision and low vibration.Construction Machinery: Equipment such as excavators and tunnel boring machines that need to transmit extremely high torque.Wind Power Generation: Increases the low speed of the wind turbine to the high speed required by the generator.
