Analytical algorithm for time-varying meshing stiffness of modified herringbone gear pair
Xibei Gongye Daxue Xuebao/Journal of Northwestern Polytechnical University, 2022 This paper jointly uses the slicing method and the potential energy method to propose an analytical algorithm that considers the meshing stiffness of the modified herringbone gear pair and its axial force. The calculation results are compared with the finite element and ISO calculation results to verify the accuracy of the analytical algorithm.
