Abstract

Hertz contact theory and experimental methods are respectively adopted to analyze and study the relationship between the load and the axial stiffness, the radial stiffness and the overturning stiffness of the three-row-roller slewing bearings. The axial stiffness, the radial stiffness and the overturning stiffness of the three-row-roller slewing bearings are theoretically analyzed on the basis of Hertz contact theory. The finite element simulation calculation model of the bearing was established to verify the validity of the theoretical stiffness analysis. The theoretical analysis of the stiffness are approximately consistent with the results of the finite element simulation calculation. The oretical analysis and experimental result show: the axial stiffness, the radial stiffness and the overturning stiffness of the three-row-roller slewing bearings present nonlinear change rule ; Rigidity value are increased along with load increase and the tendency of the increase is gradually reduced.
