- Abstract
A mechanical model based on load distribution factors is established for double-row different - diameter ball slewing bearings used in precision inertial navigation test turntable under combined action of axial load and overturning torque. Firstly, the ball load distribution factors of upper raceway and lower raceway are defined respectively by using deformation compatibility conditions of the bearings, and the relationship is deduced between two load distribution factors. Then, the equilibrium equations expressed by load distribution factors are established based on force equilibrium conditions of the bearings. Finally, the load distribution factors satisfying the equilibrium equations under given loads are obtained through traversal search. On this basis, the ball load distribution is obtained by further calculation, and the life of the bearings under multiple working conditions is calculated by using obtained ball loads, so the selection and verification of the bearings are realized.
