摘　　要：从理论上分析了偏心对摆线轮磨齿的影响,通过对偏心进行补偿,可有效提高摆线轮的磨齿精度。在磨床与工件的空间几何关系的基础上,建立磨削误差的几何模型,按照GB/T 10095.1—2008标准,分析了偏心对摆线轮齿距、螺旋线和齿廓误差的影响。基于数控摆线齿轮成形磨齿机磨削原理,提出了一种径向及切向综合补偿法。在国产YK7350B型数控摆线齿轮成形磨齿机上对摆线轮进行偏心安装磨削实验验证,结果表明,通过该补偿方法可有效提高摆线轮成形磨齿精度,降低齿面接刀痕。The influence of eccentricity on the gear grinding of the cycloidal gear is theoretically analyzed.By compensating the eccentricity,the gear grinding precision of the cycloidal gear is effectively improved.On the basis of the spatial geometric relationship between the grinder and the workpiece,the geometric model of the grinding error is established.According to the standard GB/T 10095.1—2008,the influence of the eccentricity on the pitch,helix and profile errors of the cycloid is analyzed.Based on the grinding principle of CNC cycloid gear forming gear grinding machine,a comprehensive compensation method of radial and tangential is proposed.The eccentric installation and grinding test of the cycloid wheel is verified by the domestic YK7350B CNC cycloid gear forming and grinding machine,which shows that the compensation method can effectively improve the forming and grinding accuracy of the cycloid wheel and reduce the cutting marks on the tooth surface.
