Abstract
Gear manufacturers need a dependable, comprehensive, and efficient inspection method to ensure manufacturing accuracy. Linear structured light provides a swift and effective solution to meet the rapid testing requirements of gear manufacturers. But its accuracy still needs to be improved. This method can obtain 33000 3D data points of a single gear tooth surface in less than 0.3 s. And based on this, evaluate the tooth profile error of the gear. The results indicate that the measurement deviation amounts to 1.47 μm in measuring gears of level 7 accuracy compared to the gear measurement center. The error mainly comes from the equipment error and the down-sampling process using the centroid method. In the measurement process, the larger the deviation between the contact position of the gear and the light and the focus position of the linear structured light, the greater the error. The larger the neighborhood search radius during the calculation process, the larger the error.
