introduction：Ball bearings in angular contact[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。]pre-destruction，It provides users with sufficient discovery time，Dont ignore the friction，It slows down the speed of the ride，It takes more energy and less speed over long distances。If the roughness of the surface is subtle，If the lubricating oil film has the appropriate thickness，Then surface

introduction：Surface heat treatment process in which the workpiece is heated locally by induced current。This heat treatment process is often used for surface quenching，It can also be used for local annealing or tempering，It is also sometimes used for integral quenching and tempering。20century30Early era，America、The Soviet Union began to use induction heating methods to quench the surface of parts。With the development of industry,Induction heating heat treatment technology has been continuously improved,The range of applications is also expanding。 Basic principle Place the workpiece into the sensor(coil)Within the(figure1[Principle of induction heating])，When a certain frequency of alternating current is passed through the inductor,Alternating magnetism is generated all around
