The main reason for the impact on the performance of iron, Ken bearing

Iron, Ken bearing belongs to the imported bearing in the precision parts, bearing on mechanical services, preventive maintenance means, condition monitoring and a series of maintenance decision support system to achieve the optimization efficiency and maintenance workshop assets. So the bearings for certain industries, has played a vital role. But if there is a bearing. The following of defects, it can no longer continue to use, new bearing should be replaced immediately. Specific as follows: ( a) Bearing inner ring and outer ring, rolling element and cage have crack or gap on any one; ( b) Bearing ring, rolling body on any fracture; ( c) Bearing raceway surface, guard, with significant roller card injury; ( d) Bearing cage wear significantly, or rivet significant relaxation; ( e) On the raceway surface, rolling element bearing with rust and injury; ( f) On the raceway surface, rolling element bearing has serious indentation and mark; ( g) Bearing inner ring diameter or outer diameter surface has obvious creep; ( h) Due to the hot color is obvious. So when the iron, Ken bearing appeared the situation, please do not continue to use new bearing should be replaced immediately. To avoid unnecessary accidents. 1, the purity of the influence on bearing life bearing greater influence on bearing life, bearing was made specifically for this test, the result is the difference for several times or even dozens of times. The higher the purity of the bearing, the longer the life and others test showed that different cleanliness of lubricating oil had a great influence on the ball bearing life. So, to improve the purity of the lubricating oil can prolong bearing's life, in addition, if the lubricating oil containing dirt particles control under 10 um, bearing life is growing into 7 times. 2, to the influence of vibration noise ( 1) Influence on vibration of iron, Ken bearing test center test results show that the cleanness of the serious influence bearing vibration level, especially the vibration of the high frequency band. High cleanliness of low vibration velocity values, especially in high frequency band. ( 2) Dust from the noise impact on bearing grease for noise test, the influence of proof dust, the more the greater the noise. 3, affect the performance of lubrication reduced iron, Ken bearing cleanliness, not only affect the formation of lubricating film, still can cause the deterioration of the grease and accelerate its ageing, thus affecting the grease lubrication performance degradation.
