Meshing Stiffness Analysis of Gear Using the Ishikawa Method

Meshing synthesizing stiffness of teeth is the comprehensive effect of all teeth in the whole meshing region, which is related to elastic deformation of single tooth, comprehensive elastic deformation of a pair of teeth and overlap ratio of gear. This paper adopts Ishikawa method which is commonly used in the calculation of tooth deformation. MATLAB software is used for the programming of Ishikawa formula, and then the value and distribution of gear deformation stiffness are obtained, which realizes the purpose of reducing high-order harmonic excitation in the dynamic equation, thus providing a reference frequency to avoid resonation in low-frequency region.
