TIMKEN bearing operation in testing analysis on a regular basis

1. TIMKEN bearing if get good lubrication, and cut off the right moisture and debris, said oil seal should not wear. However, best when open the bearing box, check the bearing and periodically check the oil seal. Check of the condition of the near the bearing oil seal, in order to ensure that they are enough to prevent hot liquid along the axis of infiltration or corrosive liquid or gas bearing, oil seal if already wear should be replaced as soon as possible. 2. High temperature often said TIMKEN bearing is in abnormal situation. High temperature also harmful to within the bearing lubricant. Sometimes bearing overheating can be attributed to bearing lubricant. If the bearing in more than 125 degrees Celsius temperature operation for a long time, will reduce the bearing life. The causes of high temperature TIMKEN bearings include: insufficient lubrication or excessive lubrication, lubricants containing magazine, heavy load, bearing damage, clearance, and the oil seal of high temperature and friction and so on. 3. Check the status of the operation of the machine, monitoring, lest cause the equipment downtime. Preventive maintenance of equipment, operation and peripheral parts replaced was removed when bearing inspection, judge can use or using again as a condition of good from bad. Carefully investigate and record the TIMKEN bearings and appearance of were removed, in order to explore the residual amount of investigation and lubricant, after sampling, to clean the bearing well. Second check the raceway surface, rolling surface and cooperate with the surface condition and wear conditions of cage without damage and anomalies. Judge TIMKEN bearing can use again, to the extent of the damage in considering bearing, machine performance, importance, and operation conditions, such as inspection period to decide later. Test results, if found damage and abnormal situations, bearing injury section for find out the reason, make the countermeasure. In addition, the test results, there are some defects, if the bearing can't use, need to replace new TIMKEN bearings. 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。 Sealed bearing grease sealing and dust cover breakage to serious.
