Troubleshoot spherical roller bearings

Bearings need to be maintained and maintained from time to time during use. Even so, it is inevitable that some failures will occur during the use of bearings. We can better repair the use of bearings and analyze the spherical roller bearings when they fail. How can we In order to find the real fault, troubleshooting is the best solution.

Spherical Roller Bearing Faults in Air Compressor Head and Elimination Methods.

1. Check whether the connecting rod bushing, connecting rod bushing, and main shaft skf bearing are worn, strained or burned, whether the connecting rod bolt is loose, and check whether the main oil passage of the air compressor is unblocked; it is recommended to replace the severely worn or strained bearing bush, Bushing, main bearing, skf bearing, tighten the connecting rod bolts (torque specification 35-40N.m), align the air compressor oil inlet hole with the compression air hole; air dredge the main oil passage. When reassembling, pay attention to the spindle bearings.

2. Check whether the grooves of the main and driven pulleys are consistent, if not, please replace them, and adjust the tightness of the belt (press down the belt with your thumb, and the distance between the belts should be 10mm).

3. Check the lubricating oil inlet pressure and whether the oil pipeline is damaged or blocked. If the pressure is insufficient, adjust, clean up and replace the failed pipeline immediately; check the oil quality and impurity content of the lubricating oil, compare it with the operating standard, and replace it immediately if it exceeds the budget ;Check whether the air compressor is supplying oil, if there is no oil supply, a comprehensive inspection should be carried out immediately.

4. Check whether the fixed skf bearing bolts of the air compressor are loose and tighten them.

5. For gear-driven air compressors, it is also necessary to check whether the gears are loose or the fit of the gear device and the clearance of the skf bearing. If the nut is loose, tighten the nut, and if there is a problem with the fit, it should be replaced.

6. Remove foreign matter. Deep groove ball bearings, tapered roller bearings, spherical roller bearings, cylindrical roller bearings, needle roller bearings, outer spherical bearings.
