Abstract：[Objective]Composite hybrid gears have attracted wide attention from domestic and foreign scholars due to their advantages in weight reduction and vibration noise control.However,analyzing the meshing characteristics of hybrid gears based on tests is usually time-consuming and laborious.Therefore,a meshing stiffness calculation method suitable for hybrid gears with sinusoidal waveform web was proposed.[Methods]Firstly,based on the multi-scale analysis method,combining with the mechanical properties,microstructure,and macrostructure of the microscopic carbon fiber yarns,the mechanical properties of composite laminates were predicted,and the equivalent engineering elastic constants of the composite material were obtained.Secondly,from the perspective of energy method,the matrix stiffness was calculated by finite element method,and the meshing stiffness of the hybrid gears was calculated.Finally,the influences of composite ply angle and composite web shape on the gear meshing stiffness were compared and analyzed.[Results]The results show that the ply angle has a coupling effect on the meshing stiffness of hybrid gears.Quasi-isotropic layup not only helps mitigate the influence of composite anisotropy on gear meshing,but also increases the meshing stiffness of the hybrid gears.Increasing the sinusoidal amplitude and the number of sinusoidal cycles in web waveform parameters also contributes to improving the meshing stiffness of the hybrid gears.
