THE SWAGING TECHNOLOGY USED IN SHAFT CLINCHING
ASSEMBLY FOR AUTOMOTIVE HUB BEARING UNIT
Abstract: Recently, shaft end clinching is being adopted in the hub bearing unit assembly, which will raise as technological trend and gradually replace clamp nut in future. In a machine reconstructed from lathe, the sample of shaft end clinched hub unit is successfully manufactured by swaging technology with given parameters. Some tests confirm that the shaft end clinching hub unit has functions greater than the traditional hub unit with clamp nut. In the end, the future application and the further research direction of the swaging technology are discussed.
Key Words: hub bearing unit, swaging, shaft clinching, assembly
Hub unit bearings are widely being adopted for cars as they are lighter and stronger and easily to mounting. In the hub bearing unit assembly, the shaft clinching tightening replaces clamp nut and becomes technological trend. It is adopted in the mostly famous international companies of bearing manufacture. However, the deformation of the workpiece in clinching process is complex and difficult to be controlled. It brings phenomenons such as distortion of structure in the connecting area, shortage of supporting rigidity, inadequacy of strength, disqualification of rotational accuracy and lack of life. Thus leads the hub unit to invalidation easily. Up to now, the swaging technology used in shaft clinching for hub unit is not well mastered. With the support from some corporations, the pilot study of the swaging technology is completed. The problems from technics and equipment of clinching are solved, and the sample of swaged edge of hub bearing unit is manufactured successfully.
