What are the reasons for the abnormal sound of the transmission shaft? 1. Transmission Shaft flange connection or connection bolt loosening, causing abnormal sound. 2, the grease mouth is commonly known as the butter mouth, cross-shaft oil channel plug into the grease, not filling grease, cross-shaft oil seal damage and oil leakage, etc. , the Cross shaft needle roller bearings in the long-term lack of lubricating oil working conditions, so that the Cross Journal, needle roller and sleeve wear too large, forming loose open and cause abnormal sound. 3. The gimbal cross is too tight. 4, Sleeve and universal joint fork hole with loose Kuang, supporting piece bolts loose cause sleeve rotation, make universal joint fork hole wear too large, loose Kuang and cause abnormal sound. 5. The splines of the second axle and the flange of the transmission are worn too much, forming loose and causing abnormal sound. 6, the transmission shaft middle support support bracket fixed bolt loose, middle support and the transmission shaft journal with loose open, middle transmission shaft back end spline and Flange keyway with loose open and back end nut loose. 7, the transmission shaft Middle Support bearing loose frame, bearing raceway damage, poor lubrication, excessive wear and loose. 8. The misalignment of the mounting position of the intermediate support bracket of the transmission shaft, the improper adjustment of the pretightening degree of the bearing, the damage of the rubber bearing ring spacer sleeve, and the excessive or small tightening torque of the fixing bolts of the intermediate support bracket cause the misalignment of the support position, etc. , because of the noise. 9. The universal joint forks at the two ends of the transmission shaft are not in the same plane, so that the constant velocity arrangement is destroyed and the abnormal sound is caused.
