Abstract    Based on the dynamic analysis of rolling bearings, the dynamic stiffness model of integrated squirrel-cage ball bearing was established and solved by GSTIFF (Gear Stiff) integer algorithm with variable step. The influence of bearing working conditions and structural parameters of cage strip on the dynamic stiffness of bearing and the integral component was studied, and compared with the results of static stiffness obtained by FEM (finite element method). The results of this paper provide a theoretical basis for the dynamic stiffness calculation and optimization design of cage-integrated elastic support.
