摘　　要：利用斜齿轮端面渐开线和螺旋线的方程,通过坐标转换方法得到在ANSYS环境下适用的关键点,从而建立比较精确的斜齿轮三维模型。并对建立的模型进行模态分析和齿根弯曲应力分析。经过有限元分析后,可以证实利用该方法建立的模型是比较精确的。建立比较精确的分析模型,对于掌握斜齿轮的齿根弯曲应力的特点和固有频率有着重要意义。Though the use of involute and spiral equation of helical gear faces, obtained by the coordinate transformation method applied in ANSYS environment, the key points can be used toestablish a more accurate three-dimensional model of the helical gear. And the model was analyzed by the modal analysis and the tooth root bending stress analysis. After a finite element analysis, it can be confirmed that the model using this method is more accurate. Establishing a comparatively accurate model for the control of the characteristics of helical gear tooth root bending stress and natural frequency is ogreat significance.
