摘要: 为了提高面齿轮副的承载性能,避免啮合时的边缘接触,提出一种局部线接触修形方法,并基于影响系数法建立了高效的承载接触分析数值模型。首先,利用齿面接触线数字化离散标准齿面,沿接触线及预设接触路径对离散节点叠加修形量,构建具有局部线接触特性的面齿轮副几何模型;其次,由几何模型建立面齿轮副网格模型,基于影响系数法建立齿面力-位移响应矩阵,利用变形协调方程及力矩平衡条件,数值计算面齿轮齿面接触应力及载荷分布;最后,验证局部线接触修形方法的有效性及承载接触分析数值计算模型的准确性。研究结果表明:预设接触路径与仿真接触路径一致,所提数值方法计算的接触应力大小与Abaqus结果吻合良好,接触应力分布一致,同时计算效率显著提升。相比于点接触方案,局部线接触有效降低了齿面接触应力并避免了边缘接触。

Abstract: To improve the load performance of face gear pair and prevent edge contact during meshing, a localized line contact modification method is proposed, and a high efficiency load contact analysis model is developed based on the influence coefficient method. First, the standard tooth surface is digitally discretized using tooth surface contact lines, and modification amounts are superimposed on discrete nodes along the contact line and a predetermined contact path to construct a geometric model of the face gear pair with localized line contact characteristics. Second, a mesh model of the face gear pair is developed from the geometric model, and a tooth surface force-displacement response matrix is established based on the influence coefficient method. The contact stress and load distribution on the face gear tooth surface are numerically calculated using deformation compatibility equations and moment equilibrium conditions. Finally, the effectiveness of the localized line contact modification method and the accuracy of the numerical calculation model for loaded contact analysis are validated. The results demonstrate that the predetermined contact path agrees well with the simulated contact path, and the contact stress computed by the proposed numerical method shows good agreement in magnitude and distribution with the Abaqus results while achieving significantly higher computational efficiency. Compared with point contact, the localized line contact effectively reduces the contact stress on the tooth surface and eliminates edge contact.
