摘　　要：直齿锥齿轮工作时齿面接触应力和齿根弯曲应力的大小直接影响其使用寿命和可靠性。基于Pro/E平台,首先采用参数化方法建立了直齿锥齿轮模型,用.IGS文件格式导入ANSYS软件中后分析了直齿锥齿轮在扭矩作用下的接触行为。通过分析齿轮啮合齿的变形、应力及其它相关接触结果,获得了齿轮轮齿的应力分布和变形规律。接触应力分布规律的研究对于精确分析齿轮的结构强度和可靠性具有重要的参考价值。When a bevel gear is working,the tooth contact stress and the tooth root bending stress has direct effect on its service life and reliability. On Pro/E flat form,a bevel gear model,which was operated with a torque ,was constructed by parameter method and be transmitted to ANSYS software by IGS file format. Through the analysis of the contact deformation,contact stress and interrelated contact result for Gear Engagement,the law of stress distribution and deformation was obtained. It has signification for reference to use the study of contact stress distribution to analyze the gear structure intensity and reliability precisely,which is demonstrated clearly by numerical calculation result.
