Abstract:In order to solve the problem of eccentric riveting or inadequate riveting with traditional method for the bearing of press wheel,which seriously affects the assembling quality and service life of bearing，analysis is done to the structure,design principle and advantages and disadvantages of the traditional riveting assembly,and a new type of riveting assembly for the bearing of press wheel is introduced,and the structure,use method and advantages of the new assembly are described.It is pointed out that the new riveting assembly for the bearing of press wheel is characterized as autoregistration and correction through the mandrel and the sliding sleeve gap,floating installation ensures the accuracy and quality of assembling.The riveting press-head has a good fine-tuning guiding function,which is easy to adjust and operate.The near-net shaping technology is efficient in production.The structure of the new assembly is simple and reasonable,the riveting pressure is controllable,and has good application prospects.
Key Words:bearing of press wheel;riveting;assembly;plastic deformation;mandrel; eccentricity
