The accuracy check of planar workpiece includes dimensional accuracy，Shape accuracy，Position accuracy and surface roughness。 1. Test of flatness error （1）Coloring process （2）Translucency method （3）The dial gauge method 2. Test of parallelism error （1）Use an outside micrometer（Or lever micrometer）measure （2）Use a dial gauge（Or dial indicator）measure 3. Test of verticality error （1）with90°
bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Damage response Injury event The original Due to the
Generally inINAbearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]In coordination with，It is important to give the appropriate amount of interference for the ferrule rotating under load。Attach the ferrule to the shaft or housing，Prevent creep in operation。But only by will bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It was mechanically driven
singleKOYOBearings cant run indefinitely，In operation，Due to various reasons will makeKOYOBearing failure。If the installation does not send、Poor lubrication，Water and dust intrusion、corrosion、Electrical corrosion can be doneKOYOPremature bearing failure。In installation、oiling、Maintenance under normal conditions，After a certain period of operation，Fatigue flaking can also occur、wear，So thatKOYObearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft
Rolling bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]It is the assembly that supports the rotation of the shaft。Its rings and rolling elements are precision machined。bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts
Now that you know that under normal circumstancesINAbearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The sound it makes，Then we can use these as criteria to determine the cause of the abnormal situation：
In order to improve the accuracy with actual installationTIMKENbearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]，You cant make bearings[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts
INAbearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]If the rolling surface is cracked、Indentation or corrosion，There will be periodic vibration and noise like riveting rivets，Its period can be fixed, but most of it has an inevitable corresponding relationship with the speed，The wound will continue in the channel，The scars appear and disappear on the ball，And this noise
