Description

Planetary row mechanism with split power output

技术领域 technical field

本实用新型涉及一种应用于工程机械驱动桥的行星排装置。The utility model relates to a planetary row device applied to an engineering machinery driving axle.

背景技术 Background technique

目前，工程机械装载机驱动桥的动力输出机构为整体式行星轮架结构带动驱动轮。内齿圈与支承轴固定不转，行星轮通过销轴与行星轮架连为一体，形成最终动力输出机构。动力经半轴传递给太阳轮，太阳轮带动与其啮合的三个行星轮旋转，由于与行星轮相啮合的内齿圈通过内齿圈轮毂固定在支撑轴上，故行星轮通过行星轴带动行星轮架带动驱动轮转动，将动力输出。其功用是将传来的动力进行降低速度增大扭矩，传至驱动轮。由于常用的动力输出机构即行星轮架为整体式，在检测及维修轮边齿轮时需拆下轮胎，维修性差。轮边结构复杂，密封也不好。At present, the power output mechanism of the driving axle of the construction machinery loader is an integral planetary wheel frame structure to drive the driving wheel. The inner ring gear and the support shaft are fixed and do not rotate, and the planetary gear is connected with the planetary gear frame through the pin shaft to form the final power output mechanism. The power is transmitted to the sun gear through the half shaft, and the sun gear drives the three planetary gears meshing with it to rotate. Since the inner ring gear meshed with the planetary gear is fixed on the support shaft through the ring gear hub, the planetary gear drives the planetary gear through the planetary shaft. The wheel frame drives the driving wheel to rotate, and the power is output. Its function is to reduce the speed and increase the torque of the transmitted power, and transmit it to the driving wheel. Since the commonly used power output mechanism, that is, the planetary wheel frame, is an integral type, the tire needs to be removed when testing and maintaining the wheel side gear, and the maintainability is poor. The wheel rim structure is complex and the seal is not good.

When the power is transmitted to the sun gear 6 through the half shaft 12 through the spline fit, the sun gear 6 drives the planetary gear carrier 3 to rotate through the planetary gear 5, and the planetary gear carrier 3 and the connecting hub 4 are connected by the bolt 1 to jointly output power, so that the half shaft The transmitted power is output to the hub 10 to complete the entire power output.

The seal between the two is sealed by an O-ring 2 . An O-ring 13 is also used for sealing between the planetary shaft 7 and the planetary carrier 3; the axial positioning of the planetary shaft 7 is end-face positioning, fixed with bolts 14, which can ensure accurate position and is simple and easy.
