SKF Bearing judgment organizational performance analysis

To ensure the quality of SKF bearings start from the following points :
Structural design is reasonable , while there have advanced, will have a longer SKF bearing life. SKF bearings are generally manufactured through forging , heat treatment, turning, grinding and assembly of multi- channel processing . The reasonableness of the processing technology , advanced, will also affect the stability of SKF bearing life. SKF bearings which affect the quality of the finished heat treatment and grinding processes, often with SKF bearing failure have a more direct relationship. In recent years, the SKF bearing surface modification layer of the study , the grinding process and surface quality SKF bearings closely .
SKF bearing materials metallurgical quality SKF bearings affect early failure of the main factors . As metallurgical techniques ( such as bearing steel vacuum degassing, etc. ) progress, improve the quality of raw materials . Raw material quality factors in the SKF bearing failure analysis in the proportion has decreased significantly, but it is still SKF bearing failure of the main factors .
Thus, in order to ensure the quality of SKF bearings from the bits and pieces .
According to the different forms of SKF bearing structure is divided into the following categories:
A, thin tile
1) SKF Bearing pillow melting of the alloy layer ;
2) SKF bearing alloy layer is badly worn , the occurrence of bites, can not use padded France when tightening ;
3) SKF bearing alloy layer or crack when the shelling ;
4) SKF bearing alloy layer is worn too serious, but can not guarantee service intervals when ;
5) SKF bearing alloy layer abrasion method requires the use of padded tightening , SKF bearings, but when the gasket thickness over 0.5mm .
B, SKF Bearings Thrust
1 ) thrust pad severe wear , thinning the thickness of 1/ 2 or more ;
2 ) when the thrust pad welded shut ;
3 ) thrust pad shelling, cracking.
C, bushings
1 ) sleeve diameter exceeds the maximum, that SKF Bearing shaft plus the maximum allowable gap ;
2 ) shaft diameter smaller than the minimum required size , and method of using a knurled not guarantee the quality requirements ;
3 ) or axle bushings occur when burning .
D, Split SKF Bearings
1) SKF bearing alloy serious wear , thinning the thickness of 1/ 2 or more ;
