At present, the use of many mechanical equipment is very important for every connecting rod and part. It is necessary to match the output power of the machinery with the required output power, and add different power outputs according to the needs. First, the cardan shaft fault diagnosis method Check whether the fastening bolts of the cardan shaft flange are loose, tighten them as needed. If the fault cannot be eliminated, remove the drive shaft assembly and perform a balance test with a balancer. If the imbalance is poor, perform a balance correction.
In the case of eliminating abnormal noise and vibration, check whether the expansion joint is installed on a standard scale. When it is installed correctly, support the car body, start the engine, and run at idle speed. When the vibration of the cardan shaft is large, use a stylus to measure the vibration part Direction and transmission amount. When the two ends of the drive shaft are not straight or bent, if the cardan shaft is obviously concave, the balance of the cardan shaft itself will be destroyed. When the spline shaft and the cardan shaft fork are cut by the lathe, Insert a mandrel smaller than the inner diameter of the shaft tube into the shaft tube, hit the recessed part again with a hammer, and then weld the cut spline shaft and the cardan shaft fork to the original position.
In order to ensure the quality of maintenance, when welding, place the shaft tube on a special bracket, first determine the number of circular symmetry spot welding points, the user corrects the amount of vibration, and welds along the circumference after correction. This process is very complicated. When the universal joint shaft has a large area of depression When damaged, the segment drive shaft needs to be replaced, and the different shafts of the cardan shaft transmit torque and rotation angle.
If the installation deviation is greater than a certain value, vibration or bearing line deviation will occur, and the bearing life may be affected. Therefore, the total circumferential clearance of the bearing should be within a certain range. The radial clearance between the cardan shaft and the bearing will increase due to wear and load. Concentration, fatigue indentation will occur when the load is too large, and finally fatigue peeling will occur, and the area will increase.
