introduction： wastageINAUniversal joint 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。]There are many reasons，All the factors affecting the design and manufacturing process will be related to the loss of bearings，Its hard to analyze。But in general，In general, it can be considered and analyzed from the two aspects of use factors and internal factors。 wastageINAThe universal-joint axis

introduction： The heat generated by the friction between the end faces of the workpiece is used to make it reach a plastic state，Then the top forging completes the welding method。When turning the workpiece, the chips tend to stick firmly to the tool head，Poor lubrication between the shaft and the bushing can also result in partial welding，Friction welding was invented from these phenomena。Friction welding can be divided into two types: continuous drive friction welding and inertia friction welding。①Continuous drive friction welding:A workpiece is rotated by an electric motor,At the same time, another workpiece is pressed towards the rotating workpiece，Make the contact surface friction with each other to produce heat and a certain plastic deformation,And then stop spinning,At the same time, the forging pressure is applied to complete the welding(figure1[Continuous drive
