摘　　要：蜗杆砂轮磨削是面齿轮的精加工工艺,蜗杆砂轮修整精度直接影响面齿轮磨削精度。本文分析了修整工艺误差对磨削齿面误差的影响规律,并提出了一种面齿轮蜗杆砂轮的成形修整工艺误差建模及补偿方法。首先,建立面齿轮蜗杆砂轮的数学模型,分析面齿轮蜗杆砂轮的成形修整原理,提出利用圆柱齿轮磨齿机的多轴耦合联动实现面齿轮蜗杆砂轮的成形修整。其次,将修整工艺误差分为轴向位置和径向位置误差,分析轴向位置和径向位置误差对磨削齿面误差的影响规律,提出成形修整工艺误差的补偿方法。最后,进行蜗杆砂轮补偿修整、面齿轮磨削加工及测量实验,实验表明:左齿面齿形误差由补偿前51.9μm到补偿后7.9μm,右齿面齿形误差由补偿前35.3μm到补偿后17.6μm,验证了误差补偿方法的有效性。Worm wheel grinding is the finishing process of face gear.The dressing accuracy of grinding wheel directly affects the grinding accuracy of face gear.In this article,the influence of dressing process error on grinding tooth surface error is analyzed.The modeling and compensation method for forming dressing errors of the worm wheel for face gear grinding is proposed.Firstly,the mathematical model of the worm grinding wheel is formulated,the forming and dressing principle of face gear worm grinding wheel is analyzed,and a multi-axis coupling linkage method for dressing the worm grinding wheel of the general cylindrical grinding machine is proposed.Then,the dressing process error is decomposed into axial position error and radial position error.The influence of axial position error and radial position error on grinding tooth surface error are analyzed,and the error compensation method of forming dressing process is proposed.Finally,the grinding wheel compensation dressing,face gear grinding and measurement experiments are carried out.The experiments show that the tooth profile error of the left tooth surface is decreased from 51.9μm before compensation to 7.9μm after compensation.The tooth profile error of the right tooth surface is decreased from 35.3μm before compensation to 17.6μm after compensation.The effectiveness of the error compensation method is evaluated.
