TIMKEN flange bearing damage repair technology is introduced

A, the vibration of the bearing TIMKEN bearing vibration damage is very sensitive, such as peeling, indentation, rust, crack and wear will be reflected in the vibration measurement, therefore, through the use of special flange bearing vibration tester ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Measured values of bearing or sensor installation position and different using conditions, thus requiring prior to each machine is analyzed by the measured value of the determined after judgment standard. Second, the temperature of bearing temperature, generally with the outdoor temperature can be predicted, if using the oil hole can directly measure the temperature, is more appropriate. In general, the temperature of the with operation began to slowly rise, 1 - After 2 hours to reach steady state. Normal temperature due to the heat capacity of the machine, heat dissipating capacity, rotational speed and load. If the appropriate lubrication, installation department, the temperature will go up sharply, appear unusually high temperature, must stop at this moment, take the necessary precautions. Using thermal device can monitor operating temperature, and implement e. automatic alarm when the temperature exceeds or stop to prevent the shaft accidents. In high temperature often is in abnormal situation. High temperature is harmful to the lubricant. Sometimes the flange bearing overheating can be classified to the lubricant. If the temperature for a long time even move to reduce the life of more than 125 ℃. The causes of high temperature including: lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, ring damage load is too large, the gap is insufficient, high friction and oil seal and so on. Second check bearing raceway surface, rolling surface and cooperate with the surface condition and wear conditions of cage with and without damage to watch the race and abnormal situation especially the running track. Wuxi bearing can use again, considering the extent of the flange bearing damage, machine performance, importance, and operation conditions, such as inspection period to decide later. Test results, if found damage and TIMKEN bearing abnormal situation, please according to the bearing damage phenomenon to find out the reason, to develop countermeasures. In addition, the test results, there are some defects, if the flange bearing can't use, need to replace new bearing. 一个。 Inner and outer ring, rolling body, to keep any of them are cracks and debris. b。 Inner and outer ring, rolling body any one strip. c。 Raceway surface, guard, significant injury of roller. d。 Maintains a badly worn or loose rivet badly. e. Raceway surface, rust and roller has a scar. f。 Had a remarkable indentation rolling surface, rolling body and make a mark. g。 Inner ring diameter or outer diameter on the creep. h。 Discoloration of overheating. 我。 Grease seal TIMKEN bearing seal ring and dust cover damage to serious.
