传动轴故障的主要原因及排除方法

Main causes and troubleshooting of transmission shaft failure

1、万向节或中间支承轴承发热

1. Heating of universal joint or middle bearing bearing.

故障现象：汽车行驶一段里程后，发现中间支承轴承处滑脂液化从油封滴出，由手触及零件发烫。

Fault phenomenon: After a certain mileage, it is found that the grease in the middle bearing drips out of the oil seal and the parts are scalded by hand.

故障原因：

Cause of failure:

a、万向节轴承或中间支承轴承缺油，排除方法：加注润滑脂；

A, gimbal bearing or middle bearing lack oil, remove method: add grease.

b、中间支承支架安装不正，排除方法：校正支架使轴承与传动轴垂直；

The installation of B and intermediate support bracket is not correct.

c、油封过紧，排除方法：应低速磨合并在刃口处加油；

C, oil seal too tight, elimination: should be running at low speed and at the edge of the oil;

d、行驶中频繁使用驻车制动器，排除方法：行驶中不用或少用驻车制动器。

D, frequently use the parking brake in the running. Exclude method: do not use or use parking brake in driving.

传动轴的十字轴承润滑不良，将会导致轴承卡滞、烧死，继而出现走外圆，使承孔磨损变形，产生冲击，导致突缘叉扭曲和断裂。因此保持对聚氨酯软管 PVC软管 隔离墩模具 u型槽模具 护坡模具 pvc输送带 尼龙输送带 天津除甲醛 北京除甲醛 十字轴承的润滑保养至关重要，特别是超载使用车辆的润滑周期应该缩短至200公里左右。

The poor lubrication of the cross bearing of the transmission shaft will lead to the stagnation and burning of the bearing, and then the outer circle of the bearing will appear, which will cause the wear and deformation of the bearing holes and impact, leading to the distortion and fracture of the protruding edge fork. Therefore, it is very important to maintain the lubrication of cross bearings, especially the lubrication cycle of overloaded vehicles should be shortened to about 200 km.
