研究了成形法加工的弧线齿面齿轮齿面接触分析及齿面修形.弧线产形齿条是由具有一定刀倾角的刀盘形成,用其推导展成加工的弧线齿圆柱齿轮和成形法加工的弧线齿面齿轮齿面方程,同时通过刀具抛物线齿廓对大轮齿面进行修形;在此基础上,建立了包括考虑安装误差在内的弧线齿面齿轮齿面接触分析(TCA)模型;最后通过算例的啮合性能分析,表明对大轮齿面修形可降低传动误差幅值和获得较好传动误差曲线,且该类传动装置对安装误差敏感性较低.
The tooth surface contact analysis and tooth surface modification of arc gear tooth surface processed by the forming method are studied.The arc generation rack is formed by a cutter head with a certain angle of inclination and is used to derive the arc tooth gear And the arc tooth surface gear tooth surface equation processed by the forming method, meanwhile, the tooth profile of the large tooth surface is modified by the tool parabolic tooth profile; and on the basis of the above, the tooth surface including the arc tooth surface gear tooth surface Contact analysis (TCA) model. Finally, through the analysis of the meshing performance of the example, it shows that the modification of gear tooth surface can reduce the transmission error amplitude and get a better transmission error curve, and the transmission is less sensitive to the installation error .
