ホブ切り歯車の単一ピッチ誤差測定の新たな手法（ガウシアンフィルタを通した歯すじ形状測定結果の適用）

抄録

Improving quality of hobbed gears must yield high accuracy of ground gears. This can be achieved by measuring hobbed gears accurately. Pitch deviations are most crucial in grinding processes with a worm type grinder. In the preset study, a new measuring method is proposed for single pitch deviations. In this method, measured helix trace data are conditioned with Gaussian Filter to be divided into short- and long-wavelength components. Single pitch deviations are calculated from the long-wavelength components around the center of facewidth. The calculated deviations showed 62.6 % lower variation in iterative measurements.
