摘　　要：针对低速工况车辆传动系统中齿轮磨损影响系统寿命问题,基于考虑齿面磨损的载荷分配系数模型和Archard磨损模型,提出了一种适用于渐开线圆柱直齿轮的齿面粘着磨损计算方法。通过与试验数据对比,验证了模型的有效性。进而研究了齿面载荷和磨损因数等因素对齿面磨损深度影响规律,仿真结果表明:渐开线直齿轮节点附近磨损量几乎为零;小齿轮齿根附近齿面磨损最为严重;单、双齿啮合交替区域齿面磨损量相对于其他位置有突变。本文提出的齿面粘着磨损计算模型可以为低速工况齿轮磨损寿命的预测提供理论基础。Aiming at gear wear in the transmission system of vehicles at low speeds,which affects the service life of the transmission system,a calculation method for tooth surface adhesive wear of involute cylindrical spur gears is proposed based on the load distribution coefficient model considering the depth of tooth surface wear and the Archard wear model.The wear amount of the tooth surface of the spur gear was obtained.The evolution rule of the tooth surface wear was studied,and the accuracy of the model was verified by comparison with the published paper.Meanwhile,the effects of tooth surface load and wear factor on the tooth surface wear depth were studied,and the relationship between the two factors was revealed.The tooth surface load will directly affect the wear coefficient and further affect the tooth surface wear depth.The simulation results show that:the wear amount of area near the pitch point of the involute cylindrical spur gear is almost zero;the wear of the tooth surface near the tooth root of the pinion is the most serious;the amount of wear on the tooth surface near the alternating area of single tooth meshing and double tooth meshing has abrupt changes relative to other positions.
