    Abstract

    This paper discusses about the new vibration model of gear pair in consideration of oil film force in order to evaluate the dynamic load in steady meshing and the impact load in tooth flank separation with sufficient accuracy. This new vibration model is constituted by combining an oil film model and a spring and damping model in series. In the oil film model, the force produced according to the wedge and the squeeze effect of an oil film between meshing teeth was modeled. Moreover, it was also taken into consideration that viscosity changes with oil film pressure. A spring and damping model represent the force generated by bending of a tooth, and fluctuation of stiffness accompanying change of number of meshing teeth and meshing position was taken into consideration. This model was applied to a pair of gears on which fixed torque acts and the camshaft drive gear which tooth flank separation generates by fluctuation torque. And comparison of a calculation result and an experimental result was performed to tooth root stress. The calculation results and the experimental results showed the good coincidence, and it was clarified that the model was appropriate.
