Application of image recognition to the analysis of spiral bevel gear's contact regions

A way of automatic recognition and cutting modification of contact trail was proposed. A system for image recognition and identification was established, providing an effective way to achieve automatic analysis and modification. The real bearing contact with the method of image recognition was preprocessed, and the image of the bearing contact profile was attained. Then, the image of the bearing contact profile was dispersed and fitted, and the real contact trail was generated. Finally, when the theoretic contact trail is approximated as closely as possible by the real contact trail, the modifications of machine-settings of pinion are evaluated.
