Baotou North Benz accessories drive shaft universal joint fault is the main shaft neck and the shaft bearing wear and deformation, the cross axis of the shaft center line which are not on the same plane, two adjacent vertical center line or not. The cardan shaft neck and bearing wear gap is too large, the cross shaft in operation as a result of shaking, Baotou North Benz parts transmission shaft centerline deviates from the rotation center line, so that the transmission shaft produces chattering phenomena and operation in the drive shaft out abnormal noise phenomenon. Wear is mainly caused by the lack of lubrication.
Universal joint cross shaft journal and bearing wear, from the use of view should not be more than 0.02 ~ 0.13MM, generally maintained at around 0.01mm. If more than 0.13MM, it will produce vibration and vibration of the transmission shaft phenomenon. If the cross shaft journal is worn out, the groove should be repaired or replaced. If the welding and repair, but also heat treatment and grinding process. After processing the requirements of the neck of the roundness of the 0.01mm, the taper can not be large (20mm length can not be greater than 0.01mm). To check the verticality of the adjacent two axis, we must ensure that the vertical. After the repair of the axis of the shaft should be in the same plane.
When the vehicle is moving, the direction of the torque transmission is consistent, and the direction of the cross shaft is also consistent. In the course of time, one side wear caused by cross shaft journal, with the passage of time, the cross shaft force side will wear increase, from the slot, so that Songkuang sound. The cross shaft can be used to rotate 90 degrees relative to the original position, thereby prolonging the service time. The assembly should be paid attention to when there will be glib towards the side of the drive shaft, universal joint fork should be freely rotated in the cross axis, there should be no clamping stagnation phenomenon does not appear to be the axial clearance. In peacetime maintenance should pay attention to grease, to prevent the lack of grease caused by the northern part of the Mercedes Benz parts of Baotou bearing and wear.
