Rolling bearing damage causes and countermeasures of limit speed method

In general, the proper use of rolling bearing, the fatigue life can be achieved. But if the accident early damage, unable to use. And the fatigue life is different, this early damage, is called the fault or accident. Much due to the installation and use, lubrication of ill-considered, from external invasion of foreign body or for the shaft and the shortage of the research of the bearing. Rolling bearing damage status such as roller bearing ring penal bruises, the reason may be out of lubricant, the brand is not suitable, for oil discharge structure is flawed, foreign invasion, bearing installation error or shaft deflection is too large, it is possible that more integrated caused by various reasons. Therefore, only investigate bearing damage, the real reason is hard to come by injury. However, if used in fully understand the bearing working condition of machines, and its periphery structure, on the basis of the situation before and after the failure of combining bearing damage, and a variety of related reasons were analyzed, and can prevent the same fault again. The typical bearing damage causes and countermeasures. Even the contemporary most advanced manufacturing technology in rolling bearing parts processing. Observe the reading with pre-tightening load variation method. Preloaded method have its downside, as is known to all. Always save to dial gauge head for its working surface in proper positions of the bearing face or shaft. 1. The bearing structure and service conditions. Different structure for different service condition; Auto bearing parts structure different its processing technology is not the same, will affect its quality. So we should develop new product structure, to adapt to the different service condition, and can be used in rolling bearing instructions indicated in the appropriate service condition or performance, to facilitate customer choice. 2. Strengthening technology research, improve the processing technology, improve the quality of processing, reduce the potential for defects of machining. As in the heat treatment on larger varieties inside and outside the circle, as far as possible in the lower quenching heating temperature, adapt to extend the time of heat preservation, to raise levels of alloy, increase the fracture strength of martensite, and on the premise of guarantee quality choose the higher tempering temperature to increase the impact toughness of artifacts. 3. Improved process monitoring method, and to promote the quality improvement of processing. Such as improve circulation channel curvature position monitoring, to improve the overall performance after auto bearing assembly, improve rolling bearing working condition.
