introduction：INAJudging whether the bearing is available，The main consideration is the degree of bearing damage、Mechanical property、significance、Operating condition、Until the next inspection period。Can no longer be used if the following defects，New bearings must be replaced。Inner ring、Outer ring、Rolling element、A crack or notch in either of the cages...

introduction：Now that you know that under normal circumstancesINAThe sound made by the bearing，Then we can use these as criteria to determine the cause of the abnormal situation： first，On hearingINAThe bearing emits uniformly and continuously“sizzle”This sound is produced by rolling elements rotating in and out of the diagram...

introduction：(1) The method of using chemical additives inINASome chemical additives are added to the bearing lubricant，Can reduce bearing noise，For example, a factory in Tianjin produces a low-noise grease containing noise reduction additives，The bearing noise can be reduced from the original basis3.9～9．2dB，Be suitable for...

introduction：(1)Temperature conditions at the time of measurement The ambient temperature at the time of measurement is specified as20℃，amongINAbearing、Gauge block、The temperature of standard parts and measuring instruments must be the same，The above method of placing them on the same metal plate is the fastest way to achieve the necessary temperature balance，Otherwise it can take hours or even days to achieve such a balance。 To get the correct measurement，Foreign countries rely on the mechanization of measurement to avoid human contact with these objects，Or wear heat-proof gloves to operate。 (2)The measurement area is specified towardsINAMeasurement of bearing inner or outer diameter，In China, it is stipulated that the measurement should be made in the area with a maximum chamfer coordinate on each side leaving the southern side of the ring，In foreign countries, it is usually prescribed to measure in the area where the two ends of the ring are each twice the chamfer coordinates。 (3)Specification of size basis The m

introduction：Use reasonable cooling methods： The influence of the cooling process on the deformation of metal after quenching is also a very important cause of deformation。Hot oil quenching has less deformation than cold oil quenching，Generally controlled in100±20℃。The cooling capacity of the oil is also critical to deformation。The mixing method and speed of quenching are affected...

introduction：When using imported medium coarse，If it makes a very harsh sound，That means its the sound of metal sliding from metal to metal。This is right.INAWhen the bearing has no effect，It will not affect the normal operation of the bearing，In this case, there is more or less unnecessary wear and tear，Lower bearing...

introduction：When the inlet bearing is operated under radial load，There are only a few rolling elements inside to bear the load，Formed by elastic contact with the ferrule“spring”The support causes the rolling body to vibrate periodically through the radial load line，The center of the shaft therefore moves vertically up and down or horizontally，Simultaneous noise。This type of vibration is called rolling through vibration，Especially at low speed performance is more obvious。 And its amplitude is related to the imported bearing type、Radial load、The radial clearance is related to the number of rolling elements。Usually the amplitude is small，If the amplitude is large, it will cause harm，To this end, the radial clearance is often reduced or the appropriate pre-load is applied to reduce。 （1）INABearing has been damaged，Should be replaced immediately。 （2）INABearing grease is too low、Excessive or iron filings and other impurities。The capacity of bearing grease shall not exceed the total volume70％，Impurities should be replaced

introduction：When the imported bearing is under radial load and the grease performance is poor，Youll hear it early in operation“click、click”Noise of，This is mainly due to the rolling element after leaving the load zone，Noise caused by sudden acceleration of a rolling element colliding with the cage，This kind of crash is inevitable but with running for a while...
