故障现象:一辆五十铃12座旅行车起步及正常行驶时,主减速器发出“咕噜咕噜”的响声,滑行时响声特别清晰,同时传动轴也有异响。分解主减速器后,检查主从动齿轮的啮合面、锥形轴承、星形齿轮、轮毂轴承都未发现异常。 故障分析:根据该车差速器不装十字轴而采用穿滑块的结构分析,左右半轴将套在差速器穿销上的滑块压得过紧,且两边压力不对称,滑块偏移中间位置,使穿销与沿块间隙消除(标准值为0.06毫米～0.12毫米),穿销受滑块的压
Symptoms: a Isuzu 12 station wagon start and normal operation, the main reducer issued a “grunt” sound, particularly clear when taxiing sound, at the same time the shaft also has abnormal sound. Disassemble the final drive, check the master and slave gear engagement surface, tapered bearings, sprocket, wheel hub bearings were found no exception. Failure Analysis: According to the car differential cross shaft is not equipped with the structure of the wear slider, left and right half shaft will be set in the differential wear on the slider pressed too tight, and both sides of the pressure asymmetry, the slider Offset the middle position, so that wear and clearance along the block clearance (the standard value of 0.06 mm ~ 0.12 mm), wear pin by the slider pressure
