Analysis on main wear failure of combined bearing


Combined bearing is a precision part, so it is required to be quite cautious in use, that is, high-performance bearing is used. If it is not used properly, it can not achieve the expected performance effect, and it is easy to damage the bearing.
Without normal lubrication, bearing lubrication has the primary impact on the fatigue life, friction, wear, temperature rise and vibration of rolling bearings. The bearing cannot be obligated. Analysis of the notice of combined bearing damage shows that 40% of bearing damage is related to poor lubrication. Therefore, the superior lubrication of bearing is an effective way to reduce bearing friction and wear.
(1) When replacing the combined bearing, carefully check the new bearing, and carefully check the shaft diameter, bearing seat hole and rotor;
(2) When assembling and disassembling the bearing, strictly implement the maintenance process and operate carefully to avoid bearing damage caused by improper assembly and disassembly;
(3) Refuel and change the oil on time to ensure that the working condition of the bearing is always in good condition;
(4) Check carefully during operation and eliminate hidden troubles in time.
