The equipment used in this article is the NewView9000 3D surface optical profilometer produced by ZYGO Company with magnification of 10x and 50x. After rotating bending fatigue test with small-size interference fit shaft, the damage morphology of the axial diameter surface of 45 steel was observed. In the test, the shaft rotates at different times, and the two contact edges and the inside of the contact surface of the shaft in the matching part are measured respectively, the surface damage is analyzed, and the surface roughness is measured.

10: Photos of the topography of different parts of the radial surface after axis rotation 2×105 times.

30: Morphologies of different parts of the radial surface after axis rotation 2×3×105 times.
