中文摘要：

以正交面齿轮传动为研究对象,建立面齿轮传动的有限元模型,运用有限元软件A N S Y S Workbenck对该模型进行模态分析,提取该模型的前6阶固有频率和振型进行分析;并研究压力角、齿数差及面齿轮孔径对面齿轮传动固有频率的影响。研究结果表明：面齿轮传动的模态振型以面齿轮振动为主,面齿轮传动固有频率随压力角、齿数差及面齿轮孔径的增大而增大,其中面齿轮孔径对其影响最大,其次是压力角,而齿数差对其影响不大。

英文摘要：

With orthogonal face-gear drive as the research object, a finite element model of face-gear drive is established.The FEA software of ANSYS Workbenck is used to analyze the model and the first 6 natural frequencies and mode shapes of the model are extracted. The influences of pressure angle, tooth number difference and face-gear aperture on the natural frequency of face-gear drive is studied. The results show that the modal vibration mode of the face-gear drive is mainly based on face-gear vibration, the natural frequency of face-gear drive increases with the increment of pressure angle, tooth number difference and face-gear aperture. In these factors, the impact of face-gear aperture is the greatest, followed by pressure angle, and tooth number difference has little effect.
