摘　　要：以某航空发动机弧齿锥齿轮箱为研究对象,提出了一套锥齿轮接触印痕主动设计的方法。首先,基于弧齿锥齿轮宏观参数和GEMS软件,进行齿面设计,得到齿轮副精确齿面;其次,考虑传动系统受载变形、轴承游隙和加工误差等因素的影响,建立弧齿锥齿轮系统级接触印痕仿真分析模型,得到锥齿轮在工作状态下的接触印痕和振动响应;然后,将上述设计齿面应用于加工,设计试验,将试验得到的接触印痕和振动响应分析结果与理论分析进行对比,验证了仿真分析模型的可靠性;最后,基于该仿真分析模型对上述齿面进行接触印痕优化设计,得到了满足强度和动态性能要求的齿面,形成了弧齿锥齿轮接触印痕主动设计方法。In this study,an aero spiral bevel gear box is taken as the research object.An active design method for the bevel gear contact pattern is proposed.Firstly,the tooth surface design is carried out based on the macro parameters of spiral bevel gears and GEMS software,and then the accurate tooth surface of the gear pair is obtained.Secondly,after considering the influence of the transmission system deformation under load and bearing clearance and machining error and so on,the system-level contact pattern analysis model for spiral bevel gears is established,and the contact pattern and the vibration response under the working condition are obtained.Thirdly,applying the above design tooth surface to machining,designing the experiment,and comparing the contact pattern and the vibration response obtained from the simulation and the experiment,the reliability of the simulation analysis model is verified.Finally,based on the simulation analysis model,the contact pattern optimization of the above tooth surface is done,the tooth surface meeting the requirements of strength and vibration performance is obtained,and the active design method of spiral bevel gear contact pattern is formed.
