Summary:Taking a transmission system under alternating axial load as an example, this paper builds the shafting model in Romax. By using the orthogonal experimental design method, the influence law of different factor level combinations on bearing performance is analyzed. The simulation results show that the axial assembly preload has a great influence on the contact stress load distribution in the inner raceway, the housing hole design tolerance of transition fit has a second influence, and the shaft design tolerance of interference fit has a smaller influence. The preload design parameters under service conditions are optimized: shaft design tolerance (k6), housing hole design tolerance (K6) and axial assembly preload (30 μm).
