introduction： In the automotive maintenance industry, maintenance personnel are widely used to lubricate the cross universal joint with ordinary butter。According to the research of the technicians concerned, this is a wrong approach。The specific factors are as follows： 1．The structural factor of the cross universal joint is that it is difficult to fill the needle bearing with the butter gun from the nozzle[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，It is used to reduce the coefficient of friction in the process of power transmission and maintain the center position of the shaft

introduction：Most of the imported bearings[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]There are many causes of damage，Such as a load that exceeds the original estimate、Ineffective seal、Too small bearing clearance caused by too tight fit and so on。Each of these factors has its own special damage pattern and will leave special damage traces。therefore，Inspect the bearing of the damaged shaft，Possible causes can be found in most cases。 Broadly speaking，trisection

introduction：As the worlds topNSKbearing[NSKbearing:Seiko Co., LTD（NSK LTD.）Be established in1916years，It is the first manufacturer to design and produce bearings in Japan。NSKThe function of the bearing fit is to makeNSKThe stationary ring and rotating ring of the bearing are respectively the stationary part of the installation part(Usually a bearing seat)And rotating part(Usually an axis)Solidify together，Thus, the basic tasks of transferring the load in the rotating state and defining the position of the moving system relative to the stationary system are realized。]As for，Very widely used。Every kind of business，The characteristics of the damage are also different。Today were going to look at the engine slide

introduction： Compared with general mechanical parts，FAGbearing[FAGbearing:The main shaft bearing is made of a solid inner ring、Outer ring、The ball、And a single row angular contact ball bearing consisting of a cage assembly with a solid window cage。]A part is a short, thin rotating surface，The rotary body determines that the processing machine tool is relatively simple，The vast majority are lathes and grinders；Short and thin determines its axial stiffness is good，The axial deformation is negligible，The radial stiffness is poor，Special consideration should be given to the tightening method during processing。 Rolling bearing parts are simple in structure，But the technical requirements are high，Therefore, there are several processing characteristics as follows：
