Planetary gear (planetary reducer) is a widely used industrial product, its performance with other military-reducer comparable products, but with the price of industrial products, a wide range of planetary gear in East China, North China, is applied a wide range of industrial applications. But also as a supporting member for lifting, mining, transportation, construction and other industries.

 

working principle
By an internally toothed ring (A) is tightly bonded on the gear box casing has a ring gear driven from an external power the sun gear (B), there is interposed a group consisting of a combination of three aliquots gear in between planetary gear set (C) on the tray of the set of planet gears rely on the output shaft, the inner ring gear and sun gear supported floating in the period; planetary gear when the power-side power-driven sun gear, it can be driven by the planetary gear rotation, and follow the internally toothed ring along the trajectory of the center of the revolution, driven by the rotation of the pinion shaft is connected to the output tray of the output power.

 

 

Important advantages

Planetary gear reducer internal use 20CrMnTi carburizing and grinding teeth with a small size, light weight, high load capacity, long life, smooth operation, low noise, large output torque, speed ratio, high efficiency, safety and performance characteristics. Both power split, multi-tooth engagement with unique characteristics. It is a broad versatility of the new gear. Maximum input power up to 104kW. Suitable for lifting and transport, engineering machinery, metallurgy, mining, petrochemical, construction machinery, textiles, medical equipment, instrumentation, automotive, shipbuilding, steel and aerospace and other industrial sectors series of new varieties WGN planetary gear reducer fixed axis , WN picture gear reducer, elasticity are contained less tooth difference reducer.

Solve the broken shaft (troubleshooting)

When the inter-drive motor and gear assembly to ensure concentricity get better, drive motor output shaft is subjected merely rotating force (torque), when the operation will be very smooth, no pulse movement. And at different heart, but also bear the drive motor output shaft from the gearbox input of the radial force (moment). The role of this radial force will make the drive motor output shaft was forced to bend, and bend with the output shaft rotation direction will be constantly changing.

If the error is greater concentricity of the radial force of the motor output shaft of the local temperature, the metal structure continue to be destroyed, it will eventually lead to a drive motor output shaft due to local fatigue fracture. When the greater concentricity error between the two, the output shaft of the drive motor, the shorter break time. In the drive motor output shaft broken at the same time, reducer input will also withstand the radial force from the drive motor output shaft regard, if the radial force exceeds the input gear can withstand the maximum radial load then its the results will also lead to the reducer input deformed or even broken or input end of the support bearing damage.
Therefore, to ensure concentricity is critical in the assembly! From the analysis of the assembly process, if the driving motor shaft and reducer input concentric, then the motor drive shaft between the surface and the bore surface reducer input will be very consistent, their contact surface closely-paste, no radial force and deformation space. And it will not fit between the assembly if different heart, then the contact surface or a gap there, and radial forces to deform the space provided.

Similarly, the reducer output shaft have broken or bent phenomenon, its causes and the same off-axis driving motor causes. But output gear is driving the motor output and the reduction ratio of the product, with respect to the motor in terms of greater output, so the gear output shaft is more easily broken. Therefore, users in the use of gear, when the output of the assembly to ensure its concentricity should pay great attention!
