introduction：At present, most of the bearings used in various mechanical industries are ball bearings、Needle roller，Only a small number of self-lubricating bearings have been used，I believe in the near future will come from lubricated bearings will be strong in adaptability、wear-resistant、Economic and other indisputable advantages and become the leading products in the bearing industry。

introduction：)The resultant force of the applied force passes through the axis of the bearing as far as possible，This requires the point of application to be uniform, symmetrical and stable，Force is applied through a sphere or parallel to an axis。

introduction：The hard particles moving with the shaft diameter are in contact with the friction surface，This is because the contact stress between the particles and the metal surface is low，They mark the surface of the bearing shell in a linear pattern；The hard particles partially embedded in the bearing surface will also mark linear scars on the bearing diameter surface，Both are called scratches。Scratches are two-body abrasive wear，The direction of the linear wound is consistent with the direction of the shaft diameter。

introduction：Cages are parts without rolling working surfaces，Its failure should not impact the inner and outer rings and rolling elements，In principle, its not on the list。

introduction：Bearing vibration is very sensitive to bearing damage，exfoliation、impression、corrosion、crack、Wear and tear will be reflected in the bearing vibration measurement，therefore，By using a special bearing vibration gauge（Frequency analyzer）The magnitude of the vibration can be measured，The specific condition of the anomaly cannot be inferred from the frequency division。The measured value varies depending on the service conditions of the bearing or the sensor installation position，Therefore, it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment criteria。

introduction：Some operators lack experience in identifying rolling bearings，As long as there is no obvious damage to the rolling bearing, continue to use it，Which later caused serious failures。Others simply remove the rolling bearing，They are replaced without inspection，Sometimes the bearings that can continue to be used are replaced。The technical condition of the rolling bearing should be checked on a special inspection instrument，A dial indicator can also be used to measure some data。But for the average operator，When these conditions are not present，This can be checked roughly by empirical methods。

introduction：1. The type of lubricating oil or grease is not chosen correctly； 2. underlubrication（Low oil level，Oil or grease leaks through the seal）； 3. The bearing clearance is too small（The mating choice is not appropriate）；
2017-03-13 Reading quantity 84
introduction：It has low hardness and high wear resistance，Although the hardness of the material is higher wear resistance，However, if a high hardness material is used as a cage，Will wear the rolling element，The rotation performance is adversely affected，Even produce“Convergent phenomenon”。
