摘　　要：以一对弧齿锥齿轮副为研究对象,建立了一种脱离齿面方程的真实齿面静态无负载传动误差模型。该模型以三坐标仪测量的齿面点为基础,通过插值形成离散点齿面,再做接触分析得到静态无负载传动误差。用该模型得到的理论齿面静态无负载传动误差与经典接触分析的结果进行对比,验证了该方法的正确性,并计算了真实齿面的STE。建立了弧齿锥齿轮副的弯-扭-轴耦合动力学模型;在该动力学模型中考虑了转子、负载以及时变啮合刚度和齿侧间隙等影响因素。将理论齿面和真实齿面静态无负载传动误差以离散点的形式引入动力学模型中,对比了两者对弧齿锥齿轮副的动力学性能的影响。Taking a pair of spiral bevel gear pairs as the research object,a static unloaded transmission error model of actual tooth surface is established,which is free from tooth surface equation.The model is based on the tooth surface point measured by the coordinate measuring instrument,the model forms a discrete tooth surface point through interpolation and obtains the static unloaded transmission error through contact analysis.The theoretical tooth surface STE of the model is compared with the theoretical tooth surface STE obtained by the classic TCA,the correctness of the method is verified,and the actual tooth surface STE is calculated.The threedimensional coupling dynamics model of spiral bevel gear pair is established.In this dynamics model,factors such as rotor,load,time-varying meshing stiffness and backlash are considered.The STE of theoretical tooth surface and actual tooth surface are introduced into the dynamics model in the form of discrete points,and their influence on the dynamics performance of spiral bevel gear pair is compared.
