英文摘要	In this study on cylindrical gears with variable hyperbolic circular arc and tooth trace (VH-CATT), the tooth surface equation of the VH-CATT gear is obtained according to the theory of meshing and differential geometry. The data points of the tooth surface are obtained using MATLAB. Then, based on the data points, a model of a VH-CATT gear pair was built using UG. Considering the geometric features, contact form, relative velocity, entrainment velocity, load, etc., an isothermal elastohydrodynamic lubrication model of a VH-CATT gear pair is established. On the basis of the existing elastohydrodynamic lubrication (EHL) theory, an isothermal EHL numerical solution of a VH-CATT gear is obtained by utilizing the multigrid method. The distribution of dimensionless pressure and film thickness under the effect of various loads and at different speeds of a VH-CATT gear pair are discussed. The results show that both loading and speed have impact on oil film pressure and oil film thickness. The second pressure peaks and the minimum film thickness of the VH-CATT gear pair are greatly affected by the entrainment velocity and load. Based on the results of the study, we can provide a guide to creating a tribological design of VH-CATT gears and provide a theoretical basis and the application of value engineering in industrial applications of VH-CATT gear pairs under high speed and heavy load.
