It is common for the clutch bearing to show faults during operation, so there is no need to see more and more Troubleshooting Analysis strange. The fault is revealed, and judgment and disposal are the key.
1. The bearing temperature is too high
During the operation of the mechanism, the part where the bearing is installed is allowed to have a certain temperature. When touching the mechanism shell by hand, it Troubleshooting Analysis should be normal not to feel hot. On the contrary, it indicates that the temperature of fag bearing is too high.
The end with too high bearing temperature is caused by: the quality of lubricating oil is unqualified or deteriorated, and the viscosity of lubricating oil is too high; The mechanism assembly is too tight (insufficient clearance); Clutch bearing assembly is too tight; The bearing race rotates on the shaft or in the shell; Excessive load; Fracture of fag bearing cage or bone roll, etc.
2. Bearing noise
Gulu bearing is allowed to have a small running sound in the office. If the sound is too large or there is Troubleshooting Analysis abnormal noise or impact sound, it indicates that the bearing is faulty.
The end cause of noise generation of Gulu bearing is relatively complex. One is that the inner and outer rings of the bearing are worn properly. Because of this kind of wear, the proper relationship between the clutch bearing and the housing, the bearing and the shaft is damaged, causing the axis to leave the correct position, and generating abnormal noise when the shaft moves at high speed.
When the bearing is tired, the metal on its surface will peel off, which will also increase the radial clearance of the bearing and produce abnormal noise. In addition, insufficient bearing Troubleshooting Analysis lubricating oil, dry friction and bearing breakage will produce abnormal sound.
After the fag bearing is worn and loose, the maintenance frame will be loosened and damaged, and abnormal noise will also occur, resulting in the damage of the bearing. When the Gulu bearing is disassembled and Troubleshooting Analysis inspected, the fault and damage end of the bearing can be judged according to the damage condition of the bearing.
The rolling body of the bearing and the raceway surfaces of the inner and outer rings bear the effect of periodic pulsating load, so the contact stress with periodic variation is initiated. When the number of stress cycles reaches a certain number, fatigue spalling will occur on the surface of the bone roll body or the inner and outer raceways.
If the load on the bearing is too large, this fatigue will be exacerbated. In addition, improper installation of clutch bearing and shaft buckling will also cause raceway spalling. Fatigue and spalling of fag bearing raceway will reduce the operating precision of the shaft and cause vibration and noise of the mechanism.
2. Bearing burning
The burning clutch bearing has a return fire color on its raceway and bone roll body. The burning end is usually caused by insufficient Troubleshooting Analysis lubricating oil, unqualified or deteriorated lubricating oil quality, and too tight bearing assembly.
3. Normative variant
The pits with uniform warping edges are exposed on the contact surface between the raceway and the roller of the bearing, which explains the normal deformation of the bearing. At its end is the clutch bearing. Under the effect of very large static load or impact load, part of the stress on the office surface exceeds the bending limit of the material. This kind of thing usually occurs on the bearing rotating at low speed.
4. Cracks on bearing race
The crack initiation end of the bearing race may be due to proper over Troubleshooting Analysis tightening of the bearing, abnormal clutch bearing or loose inner ring, deformation of the inclusion part of fag bearing, poor surface processing of the installed bearing, etc.
5. Broken maintenance frame
Its end is caused by insufficient Troubleshooting Analysis lubricating oil, broken bone roll body, seat ring skew, etc.
6. The metal of the maintenance frame is pasted on the bone roll
It is possible that the bone is stuck in the cage or the lubricating oil is insufficient.
7. The race race is severely worn
There may be foreign matters falling into the seat ring, insufficient lubricating oil or inappropriate lubricating oil brand.
