Article Preview

A key functional aspect of assembled camshafts is the joining strength between the shaft tube and the cam lobe, which is depended on the assembly or joining method. The assembly process by knurling joining and torque deformation of assembled camshaft were numerically studied and the key influencing factors on the press fit load and joining strength were analyzed. The experiments including to the press fit and torque strength of lobe/tube joining were carried out.The results show that the torque strength of the cam lobe/shaft joining can availably increase by matching cam and tube materials, choosing appropriate knurling form, enlarging magnitude of interference and extending knurling width. The numerical results agree well with the experiments and are significant in the design and manufacture of assembled camshaft.
