1.故障现象某5t轮式装载机在使用过程中出现驱动桥轮边减速器异常发热现象。拆解检查后发现,齿轮传动系统运转良好,磨损量不大,但是轮边减速器的行星齿轮架磨损严重,行星齿轮侧面的垫片已完全陷入行星齿轮架内。齿轮油变质发黑,行星齿轮架磨损情况如图1所示。2.行星齿轮架结构该装载机采用整体式驱动桥,具有2级减速装置。驱动桥中间为采用圆锥齿轮主减速器,主减速器内设有采用圆锥齿轮的差速器。轮边减速器采用直齿行星齿轮减速器。该驱动桥具有结构
1. Symptom A 5t wheel loader in the course of the drive axle reducer abnormal fever phenomenon. Dismantling inspection found that the gear transmission system is working well, the amount of wear is not, but the wheel reducer planetary gear rack wear serious planetary gear side of the gasket has been completely trapped in the planet carrier. Gear oil deterioration of black, planetary gear frame wear shown in Figure 1. 2. Planetary Carrier Structure The loader adopts integral drive axle with 2-stage reduction gear. The middle of the drive axle adopts the bevel gear main reducer, the main reducer is equipped with a bevel gear differential. Wheel reducer with a straight-tooth planetary gear reducer. The transaxle has a structure
