Analyze The Cause of Drive Shaft Failure

1. The flange joints of the Drive Shaft are loose, causing abnormal noise.

2. The grease nozzles and cross shaft oil passages are blocked and the grease cannot be injected, the grease is not filled on schedule, the cross shaft oil seal is damaged and the oil leaks, etc., causing the cross shaft needle roller bearing to lack lubricating oil for a long time. Under work, the cross journal, needle roller and sleeve wear too much, forming loose and causing abnormal noise.

3. The assembly of universal cross shaft is too tight.

4. The sleeve and the fork hole of the universal joint are loosely matched, and the bolt of the supporting plate is loosened to cause the sleeve to rotate, which makes the fork hole of the universal joint excessively worn and loose and cause abnormal noise.

5. The spline of the second shaft of the transmission and the spline in the flange are worn too much, forming looseness and causing abnormal noise.

6. The fixing bolts of the intermediate support bracket of the transmission shaft are loose, the intermediate support and the intermediate transmission shaft journal are loosely matched, the spline and the flange keyway of the rear end of the Intermediate Transmission Shaft are loosely matched and the rear nut is loose.

7. The intermediate support bearing of the transmission shaft is loose, the bearing raceway is damaged, the bearing is poorly lubricated, and the wear is excessive and loose.

8. The installation position of the intermediate support bracket of the transmission shaft is skewed, the pre-tightening of the bearing is adjusted incorrectly, the rubber backing spacer is damaged, the tightening torque of the fixing bolt of the intermediate support bracket is too large or too small, which causes the position of the bracket to deviate. Abnormal sound.

9. The universal joint forks at both ends of the drive shaft are not in the same plane, which damages the constant velocity arrangement and causes abnormal noise.
