Abstract

The invention belongs to the field of gear surface defect detection. The invention relates to a gear pitting detection system based on machine vision. The device mainly comprises a visual detection module, wherein the image processing module, the illumination module, the gear clamp module and the workbench are used for installing the modules, the core of the illumination module is a light source,the core of the visual detection module is a CCD industrial camera, the gear clamp is used for positioning and installing a gear through a three-jaw chuck, and the illumination module, the illumination module and the gear clamp module are combined to obtain pitting image information of each tooth surface of the gear; And the image processing module is used for segmenting an effective working toothsurface part from the collected image information to obtain the ratio of the number of pixels of the pitting part to the number of pixels of the working tooth surface part, so that the pitting corrosion grade of the pitting corrosion rate evaluation gear is obtained. The whole device realizes quantification of automation and gear pitting corrosion evaluation, and the pitting corrosion detection efficiency and precision are effectively improved.

Description

technical field [0001] The invention belongs to the field of gear surface defect detection and relates to a gear pitting detection system based on machine vision. Background technique [0002] Gears are the basic components for transmitting motion and power in equipment, and their working conditions are related to the operation of the entire mechanical equipment. Therefore, the measurement of gears has become an extremely critical link in the process of researching and producing gears. The traditional contact gear measurement method has low precision and heavy workload. In the measurement of gears, the determination of pitting is also a very important part of the content. Gear pitting is one of the most common damage forms of gears, and it is an important indicator of the contact fatigue strength of gear materials. It refers to the fact that fatigue spalling occurs on the contact surface of gears under long-term load work, and further small pits appear. [0003] For the f...
