Abstract

Bearing is the key component of equipment manufacturing. As the core parts of bearings, bearing rollers determine the bearing performance and reliability. In advanced bearing rollers fields, they are used in high temperature, high load, and high-speed working conditions. The existence of bearing rollers surface defects will cause huge disaster. Hence, the quality inspection of bearing rollers is very important. However, the bearing rollers material is metal and there is a certain roughness on the surface. Therefore, the light scattered on bearing rollers surface by defects is complicated. Furthermore, the advanced bearing rollers shape is not exclusively cylinder. It includes cone and drum types. The direction of reflective light on surface changes with the surface position, which will cause some illumination reflective light enter into the imaging system and interfere defects inspection. To solve these problems, a surface defects scattering simulation model is built and defects inspection illumination imaging system is designed in this paper.
