摘　　要：为了在国产数控弧齿锥齿轮机床上采用内凹刀盘加工直齿锥齿轮,对使用内凹刀盘加工直齿锥齿轮的原理和齿面接触分析(Tooth Contact Analysis,TCA)方法进行了研究。基于内凹刀盘的加工原理和结构特点,建立了内凹刀盘加工的直齿锥齿轮的齿面数学模型,给出了相应的齿面接触分析方法;编写齿面接触分析程序,计算得到了齿轮副的接触斑点和传动误差曲线;通过实际的切齿加工和接触斑点检验,验证了齿面数学模型以及TCA方法的正确性。研究为锥齿轮加工参数及刀具参数的确定与啮合质量控制提供了理论依据。In order to use the concave cutter to process the straight bevel gear on the domestic CNC spiral bevel gear machine tool,the principle of using the concave cutter to process the straight bevel gear and the TCA method of tooth surface contact analysis are studied.Based on the machining principle and structural characteristics of the concave cutter,the tooth surface mathematical model of the straight bevel gear machined by the concave cutter is established,and the corresponding tooth surface contact analysis method is given.The tooth contact analysis program is compiled,and the contact pattern and transmission error curve of the gear pair are calculated.The correctness of the tooth surface mathematical model and the TCA method of tooth surface contact analysis are verified by the actual tooth cutting and contact spot inspection.It provides a theoretical basis for the determination of bevel gear machining parameters,tool parameters and the meshing quality control.
