The damage characteristics of stripping is bearing parts work surface under the effect of the cycle of high contact stress of metal flake peeling phenomenon, has a certain depth and area;
The uneven surface scaly;
With the sharp Angle of groove.
Usually render extension fatigue characteristics of stripes on the beach.
Its form mainly include strip stripping, dot, sheet, block stripping stripping, etc.
Among them, the massive detachment is a relatively new type of strip shape.
2.
Damage causes stripping of the basic reason mainly has the following several aspects: pieces of rolling contact fatigue damage.
High pieces bearing contact load or abnormal load of impact load, such as with bad condition of bearing saddle fit or have serious wheel tread scratches, etc. , cause local overload fatigue.
In pieces bearing component material purity low or improper heat treatment technology.
In pieces bearing high additional contact stress between components caused by improper assembly.
Poor lubrication in pieces.
3.
Pieces of hurt instance caused by inclusions in pieces the raceway stripping due to corrosion of the outer ring raceway divest the bearing is disassembled found a phenomenon of mix water, oil bearing components is rust, thus determine the cause of the bearing outer ring sheet strip rust.
Bearings in pieces caused by abnormal load their pieces off due to the poor surface quality of pieces of inner ring raceway stripping due to improper heat treatment of the inner ring raceway detachment (
