Analysis of TIMKEN bearing damage degree judgment

Check of the condition of the near the TIMKEN bearing oil seal to ensure that they are enough to prevent hot liquid, corrosive liquid and gas along the axis of infiltration of bearing, oil seal, if damaged, it should be replaced as soon as possible. Check the automatic lubrication system to ensure that the oil or grease into the bearings, and to ensure that the correct amount at the same time check whether the lubricant is color or black, if has this kind of situation usually said lubricant to the impurities, this situation is the use of bearing is also harmful. By TIMKEN bearing failure and degradation, performance status parameters to judge and predict the performance, reliability, and use bearing on the part of the abnormal situation, cause and degree of risk identification and judgment, decided to repair and improve the method of comprehensive technology. Therefore, bearing fault diagnosis technology is not a simple fault detection ( Or monitoring) Responsible for counting instrumentation of technology, also is not simple. Accurately and quickly and effectively to collect signals, data processing, manual or automatic identification and judgment. In order to confirm the repair cycle science, but also according to the mechanism of all kinds of fault, to fatigue, wear life necessary test and estimate. TIMKEN bearing is available, mainly considering bearing damage degree, mechanical properties, importance, and operating conditions, to the next overhaul period. If there are the following defects cannot be used again, new bearing must be replaced. Inner ring and outer ring, rolling element and cage on any one have crack or gap. 1, ring, rolling body fracture on any one. 2, rolling on the pavement, guard, rolling body CARDS have a significant injury. 3, keep wear significant or rivet significant relaxation. On page 4, raceway and rolling body rust, injury. On page 5, raceway and rolling body severe creasing and mark. 6, inner ring diameter or outer diameter surface has obvious creep. 7, due to the hot color change is obvious. 8, the TIMKEN bearing grease sealed, sealing ring or dust cover breakage is obvious.
