Abstract:
Process for a modification of tooth traces and a correction of tooth trace deviations of a gear, said gear having a left and a right flank, wherein said process takes place while said gear is continuous tooth flank generation grinded using a gear flank grinding machine having NC axes and a grinding worm and wherein said modification and said correction take place by means of influencing a machine kinematics of said gear flank grinding machine,the process comprising the steps ofselecting a first modification and a first correction of tooth trace deviation of said left flank of said gear; selecting a second modification and a second correction of tooth trace deviation of said right flank of said gear independently of said first modification and said first correction; calculating from said first and second modifications and corrections supplementary motions of said NC axes of said gear flank grinding machine as a function of a grinding stroke position superimposing said supplementary motions on a relative motion between said grinding worm of said gear flank grinding machine and said gear, thereby producing tooth traces with said first modification and said first correction on said left flank and said second modification and said second correction on said right flank of said gear in one and the same grinding stroke.
