Abstract:In order to improve the assembly process level and efficiency of air-jet loom bearing，and improve the reliability of moving pair of air-jet loom，the raceway damage and its failure reasons of deep groove ball bearing on air-jet loom are analyzed.The assembly steps and methods of traditional bearing are introduced,and the problems of bending deformation and high demands on workers caused by cold pressing assembly process of bearing assembly are introduced.The assembly process method and application of using electromagnetic induction heating bearing is discussed.The production practice shows that the new assembly process can effectively improve the assembly precision and quality of bearings，reduce the failure rate，avoid the damage of assembly to bearings，improve the reliability of transmission system，and reduce the technical requirements on assembly workers.
Key Words:air-jet loom；bearing；failure；cold press；assembly；crankshaft；electromagnetic induction heating；process
