Bearing lubrication, grease and oil lubrication. In order to make good display performance of the combined bearing, first, to select suitable for the use of the premise, the use of the purpose of lubrication method. If only consider the lubrication oil lubrication upper hand. However, greased expertise can simplify the vicinity of the bearing structure, compare the pros and cons of grease and oil lubrication. To move bearing failure phenomenon general performance of the two and, bearing installation site temperature is too high, the second is the noise in the bearing operation.
Move bearing promised to work a little running sound, if the sound is too large or abnormal noise or crash, indicates that the bearing failure.
Move bearing noise generating more complex reasons, one is the bearing inner and outer mating surface wear. Because this wear, with the relationship of the destruction of the bearing housing, bearings and shaft, the axis deviated from the exact location, generation of abnormal noise in high-speed movement of the shaft. When the bearings when you are tired, the surface of metal falling off, make the bearing radial clearance increased generation of abnormal noise. In addition, the combination of lack of bearing lubrication, the formation of dry friction, and bearing broken will have an unusual sound. The bearing wear Songkuang cage loose damage, will produce abnormal noise.
Bearing move the body and the inner and outer ring raceway surface are exposed to periodic pulsating load, resulting in changes in contact stress cycle. When stress the number of cycles reaches a certain value, or in the move, the working surface of the outer ring raceway fatigue spalling. If the bearing load is too large, this tired intensified. In addition, the bearing installation is not correct, shaft bending, will produce raceway spalling.
The bearing raceways tired peeling will reduce the axis running accuracy, so that the institutions of the vibration and noise.
Burn bearing its raceway, heat tint on the move. The burn generally due to lack of lubrication oil quality does not meet the requirements or deterioration, and bearing assembly tight.
The bearing raceway and roller contact surface of the float to the surface uneven pits, the bearing plastically deformed. The reason is that a lot of static load or impact loads bearing, the working surface of the local stress exceeds the material yield limit, which generally occurs in the combination of low-speed rotation bearing.
The bearing race cracks may be due to the bearings with tight, loose bearing foreign or inner bearing inclusive deformation, poor bearing surface processing installation.
The operation of the institutions, install the bearing parts promised a certain temperature the hand stroked actuator housing should not feel hot as normal, on the contrary it indicates that the bearing temperature is too high.
Bearing temperature is too high: oil quality does not meet the requirements or deterioration, lubricant viscosity is too high; institutions the tight assembly (lack of space); the combination bearing assembly tight; bearing ring on the shaft or shell rolling ; the load is too large; bearing cage or move body fragmentation
