A Virtual Measurement Method of the Transmission Error Based on Point Clouds of the Gear

Abstract As the most widely used gear measuring instrument, center can measure individual deviations of a tooth flank other than comprehensive gear. However, transmission error is an important performance indicator in meshing process. It trend to obtain from deviations. In this study, calculation method proposed based on point clouds obtained by optical sensors. According principle, introduced determine contact status between flanks formed clouds. method, single pair process and multiple pairs are analyzed curve. The comparison results analysis measurement experiments verify virtual method.
