introduction：Plain bearings on an engine[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。]There are many kinds，Both the bushing and the bearing are plain bearings。In order to ensure the accuracy of engine operation，The operating clearance requirements of these plain bearings are also very high。Engine plain bearing failure causes can be attributed to：Lubricate critical state and cause damage
