FAG cylindrical roller bearings are several ways to deal with failure

FAG bearings based on the work surface grinding metamorphic layer formation mechanism, the impact grinding metamorphic layer of the main factors is the grinding heat and grinding force. Following analysis of cylindrical roller bearings on the reasons for failure.
1 pre-load main objectives: The main purpose of the pre-load and representativeness may be exemplified by some examples to prove a look:
(1) determine the axis in the right direction and the axial direction of the radial positions, while suppressing the shaft runout.
(2) increase the FAG bearing stiffness. The spindle bearing, pinion gear differential mechanism cycling bearings.
(3) to prevent the axial direction of the vibration and the resonance caused by the abnormal sound. Small motor bearing.
The load is applied to bear with the cylindrical roller bearing, because it is exposed to the load increase in the number of rolling bodies, friction increases, heat is increased, poor lubrication and cooling conditions, and the effect of force on the cage increases, so , it is necessary FAG Roller bearing based on the type and size of the load angle, the bearing speed limit to be multiplied by a reduction factor f2 swap.
If the selected cylindrical roller bearing speed limit speed can not be satisfied with the application requirements, can be used in some way to be progressive improvement of skills in order to reach than satisfy requests. Such as increasing the bearing tolerance poor grade; appropriate increases clearance; instead insist on particular data and improved frame structure; transition lubrication methods, such as taking oil and gas, oil mist with spray lubrication; improved cooling conditions.
In the course of using the FAG Bearings are prone to temperature rise of the phenomenon. When the cylindrical roller bearing temperature rises, first determine whether misuse, as indeed increased, should be done as follows
Treatment:
 (1) Check the cooling water pressure, flow and piping systems are normal. If water filter may be clogged down and can not handle, you can stop processing, when the confirmation able to work, and then put into use.
 (2) should be checked governor oil pressure, oil pressure may result if the cooling water hydraulic valve is closed.
 (3) Check whether there is abnormal sound FAG bearings, cylindrical roller bearings and detect whether there is abnormal swing.
 (4) Take oil samples observe whether there is oil color changes, and conduct tests to see whether the deterioration. If confirmed deterioration should be replaced with new oil shutdown.
 (5) Check the oil standard oil level is normal, if not normal, check the tank drain valve is closed. If you have already closed, should fill the oil, if it is sealed cushion permeability should stop processing.
