Abstract:This study considers the tooth spall morphology and establishes a kinetic model of a high contact ratio gear pair system with an ellipsoid tooth spall defect. The mesh stiffness of the spalled gear system was evaluated using the potential energy method. To obtain the accurate dynamic response, the friction force was incorporated into the gear kinetic model. The dynamic transmission error and dynamic meshing force under different rotational speeds were acquired by the proposed model. The dynamics of a healthy g… Show more
