Metamorphic layer formation mechanism of the FAG bearing surface grinding, grinding metamorphic layer grinding heat and grinding force. The following analysis of the cylindrical roller bearing failure.
1 The main purpose of the pre-load: The main purpose of the pre-load and representative examples can be cited to prove that in some instance to
find out:
(1) location in the right decision axis in the radial direction and axial direction at the same time, inhibition of the axis of the beating.
(2) increase the rigidity of the FAG bearings. Machine tool spindle bearings, cycling differential, pinion bearings.
(3) to prevent the axial direction of vibration and abnormal noise caused as a result of the resonance. Small motor bearings.
Withstand the combination of the load of cylindrical roller bearings, due to the increase in the number of rolling body to bear load, friction increases, the fever increased in poor lubrication and cooling conditions, and acting on the cage force increases, so , the size must be based on FAG bearing type and load angle, bearing the limits of speed multiplied by a lower coefficient of f2 to swap.
If the selected speed limit speed cylindrical roller bearings can not be satisfied with the application requirements, we can use some improvement skills approach to be progress, to reach more to meet the request. Such as to improve the level of bearing tolerance; appropriate to increase the clearance; switch to special information and improved adhere to the frame structure; change the method of lubrication, such as to take the oil and gas, oil mist and spray lubrication; improved cooling conditions.
