【 Jiaxing bearing 】 Rod end joint bearing manifestation of erosion effect on life

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Bearing by using environment is different, so the erosion performance are also different, because the erosion in a different way. Rod end joint bearing, of course, also won't get away eroded this fate, below is speaking about a shaft rod end joint bearing erosion in three ways. 1, cavitation cavitation of rod end joint bearing contact with the liquid and solid surface is generated by the relative motion form of surface damage. When the lubricating oil in the oil film of low pressure area, oil will form bubbles, the bubbles movement to high, the pressure under the action of air bubble breaking, the breaking of instant impact and high temperature, solid surface under the effect of the impact of repeated, material fatigue peeling, the friction surface appear small pits, and then developed into the cavernous scars. Overload, high speed, and the sliding bearing with higher load and speed, often occurs cavitation; 2, fluid erosion, rod end joint bearing fluid erosion refers to the fluid of fierce shock can cause fluid solid surface erosion, point to appear on the solid surface scars, the damage of the surface is smooth; 3, the electric erosion bearing electrical erosion refers to as motor or electric leakage, the rod end joint bearing friction surface between edm, caused dot on the friction surface scars, is characterized by damage reciprocating appear on the surface of the journal that hard. To predict the fatigue life of rolling bearing, residual life, we have to know all of the bearing fatigue damage phenomenon, this will take a long time. However, due to the rolling fatigue happened under the compressive stress of contact fatigue, to achieve damaged great material changes will occur. Therefore, in addition to early crack, raceway surface appear to suffer before chemical effect, the propagation of the crack material change, testing materials change might judge rod end joint bearing fatigue. Rod end joint bearing fatigue, can through the raceway surface residual stress measurement by X-ray machine, the half width of the diffraction line, the residual austenite dimension to grasp the change. These values, will be as the change of fatigue intensifies and appear. Due to residual stress will increase at the beginning of the fatigue and reaching saturation value, therefore, can be used to detect slight fatigue, but in fatigue larger extents, half width of the diffraction line with the change of retained austenite is associated with fatigue intensifying has certain. The X-ray test values as an index ( Fatigue index) , to find the relationship between and the bearing endurance test time.
