摘要: 为揭示变双曲圆弧齿线圆柱齿轮(VH-CATT圆柱齿轮)齿面磨损特性,结合Archard磨损理论与主平面重合的椭圆等效接触模型,建立了VH-CATT圆柱齿轮传动界面磨损模型,利用有限元方法获取了齿面法向载荷与接触压力,通过数值计算验证了所建立模型的正确性,并探究了准静态工况下VH-CATT圆柱齿轮传动的齿面磨损规律。研究结果表明,VH-CATT圆柱齿轮沿齿线方向的磨损深度呈半椭圆形分布,在齿根附近磨损深度最大,在节圆附近磨损深度最小,啮合频次的增加对齿面磨损深度的影响逐渐趋于平缓;通过设计参数的敏感性分析可知,增大传动比、模数、齿线半径、压力角可以有效地改善齿面磨损。研究可为提高VH-CATT圆柱齿轮传动精度与效率、减磨延寿提供理论基础。

Abstract: In order to reveal the wear characteristics of the Cylindrical Gear with Variable Hyperbolic Circular-arc-tooth-trace, a VH-CATT gear transmission interface wear model was established by combining Archard’s wear theory with the elliptic equivalent contact model coexisting with the main plane. The normal load and contact pressure of the gear surface were obtained by finite element method. The correctness of the model was verified by numerical calculation, and the wear law of the tooth surface of VH-CATT gear transmission under quasi-static condition was investigated. The results show that the wear depth of VH-CATT gears presents a semi-elliptic distribution along the tooth line, with the maximum wear depth near the root and the minimum wear depth near the pitch circle. The influence of increasing meshing frequency on the wear depth of the gear surface gradually becomes gentle. Sensitivity analysis of design parameters shows that increasing transmission ratio, modulus, tooth line radius and pressure angle can effectively reduce gear surface wear. This research can provide a theoretical basis for improving the accuracy, efficiency and reduce wear and life-span of VH-CATT gear.
