十字轴万向节在工作中承受着较大的扭矩和交变负荷,其损坏形式主要是十字轴轴颈和滚针轴承的磨损、十字轴轴颈和滚针轴承碗工作面的压痕与剥落。 在车辆维护规范中规定:滑动叉键齿和中间轴承使用钙基润滑脂(黄油);十字轴的滚针轴承和三桥驱动汽车的中间轴承使用齿轮油。但在实际工作中,因十字输的注油嘴与黄油嘴相同,有时是为了操作方便,有时是无加注设备,很多驾驶员和保修人员便错误地对十字轴滚针轴承使用黄油润滑,造成十字轴的早期损坏。
Cross-axis universal joint in the work to bear a greater torque and alternating load, the main form of damage is the cross-shaft journal and needle bearing wear, cross-shaft journal and needle bearing bowls indentation and Peeling off. In the vehicle maintenance specification states: the use of calcium-based grease grease (butter) for the sliding key and the middle bearing; gear oil for the needle bearings of the cross shaft and the intermediate bearings of the Mihashi-driven car. However, in actual work, due to cross-shaped oil nozzle and butter mouth the same, sometimes for ease of operation, sometimes without filling equipment, many drivers and warranty personnel mistakenly use the cross-shaft needle roller bearings grease lubrication, resulting in Cross shaft of the early damage.
