摘要
根据齿轮啮合原理,推导了双压力角非对称齿形面齿轮的齿面方程.在有限元软件ANSYS中建立了面齿轮副轮齿接触有限元分析模型.通过有限元接触压力计算结果与基于点接触Hertz理论接触压力计算结果的对比分析,确定了有限元模型的网格密度.由若干组算例的计算结果表明,适当增大工作侧齿面压力角可以明显降低面齿轮副接触压力和齿根弯曲应力,因此,非对称齿形设计可以获得更高的轮齿强度.
The equations of tooth surface of double pressure angles asymmetric face gear were conducted according to the theory of gearing. A contact finite element model was established in software ANSYS. The contact pressure calculated from finite element model and the calculated value of contact pressure which was given by the point-contact Hertz theory were compared to determine the element density of the finite element model. Several groups of parameters were calculated. The results show that appropriate increment of the pressure angle of driving side can obviously decrease contact pressure and root bending stress of face gear. Therefore, the applying of asymmetrical design can improve the static load capacity of face gear.
