摘　　要：磨损是齿轮的主要失效形式之一,研究其磨损特性对变双曲圆弧齿线圆柱齿轮的主动设计有指导意义。基于Hertz接触理论和Archard磨损计算通式,建立变双曲圆弧齿线圆柱齿轮的磨损模型,计算了齿面各点磨损量随工况参数和设计参数的变化规律。分析表明,变双曲圆弧齿线圆柱齿轮副齿面磨损沿齿廓方向从齿根到齿顶先减小后增大,且齿根区域的磨损量大于齿顶区域的磨损量,节圆附近磨损量最小;沿齿宽方向呈对称分布,中截面磨损量最大,从中截面到两端面磨损量依次减小。研究可为变双曲圆弧齿线圆柱齿轮的失效研究和寿命预测提供理论基础。Gear wear is the the main failure form,the study of wear characteristics is instructive to the ac-tive design of cylindrical gear with variable hyperbolic circular-arc-tooth-trace(VH-CATT).Based on Hertzcontact theory and Archard wear calculation formula,the wear model of VH-CATT cylindrical gear is estab-lished,and the wear law at each point of tooth surface considering working condition parameters and design pa-rameters are analyzed by numerical calculation.The analysis results show that the tooth surface wear of VH-CATT cylindrical gear pair decreases firstly and then increases from tooth root to tooth tip along the tooth profiledirection,and the wear amount in tooth root is greater than that in tooth tip area,and the wear amount in pitchcircle area is the smallest.It is distributed symmetrically along the tooth width direction,with the largest wearin the middle section and decreasing in turn from the middle section to the two end faces.The above researchcan provide theoretical basis for failure studies and life prediction of cylindrical gear with variable hyperbolicarc tooth line.
