Contact fatigue failure means TIMKEN bearings surface by alternating stress to produce failure. Contact fatigue spalling TIMKEN bearings work surface, often accompanied by fatigue crack from the contact below the surface of the largest alternating shear stress at first, and then extended to the surface to form a different shape of peeling, such as point-like flaking pitting or pitting , flake into small pieces known as shallow spalling. Peeling surface gradually expanded, and often extended to the deep, forming a deep peeling. Deep peeling is the source of the contact fatigue failure of fatigue.
TIMKEN bearings a Card injury phenomenon state
Adjustment of a backlash, cylindrical and oval-shaped bearings, can be manually scrape TIMKEN bearings the carved face padded turning repair scratch.
2, cylindrical and oval bearings the headspace can be manually scrape TIMKEN bearings the carved face and pad adjustment as circumstances permit.
Oily wedge fixed bearings, in principle, allowed to repair scratch and adjust the bearings clearance gap inappropriate should be replaced with new tile.
4, wedge tilting bearings on more oil, does not allow repair scratch pad gap inappropriate should be replaced due to tile. Thickness adjustable tile by tile behind the adjustment block and stainless steel pad, or thinning of the block thickness adjustment method to adjust the tile amount. Note the tilting bearings multi-oil wedge, tile thickness error of the same group should be less than 0.01mm.
