Problems solved by technology
There are still many deficiencies in the linear detection of the wear condition of the split gears. The previous detection scheme is to analyze the wear particles after sampling the split gears to indirectly understand the wear of the gears. However, this analysis only indirectly predicts the wear status and cannot reflect the wear of the gear teeth. Surface wear status
Moreover, due to the existing optical analysis, due to the oil coverage on the tooth surface, the color of the oil will turn black due to friction and other effects during oil work, which seriously affects the analysis results.

Embodiment Construction
[0037] The specific implementation of the invention will be further described below in conjunction with the accompanying drawings.
[0038] In the prior art, the wear detection of the gears can generally use the online abrasive particle analysis of the oil pollution status, and then obtain the wear status of the gears, but this detection can only analyze the wear status within a lubrication cycle, focusing on the lubrication The analysis of whether the fluid or grease needs to be replaced does not give a specific analysis of the actual situation of tooth surface wear and how the wear performance is. Another kind of gear wear detection is to analyze the wear of the gear teeth after disassembly and cleaning; the most commonly used is the static inspection by technicians, such as checking whether there are scratches, plastic deformation, pitting, peeling and abrasive wear etc.
[0039] For open gears, the wear condition is more complicated, relying on manual inspection often can...

The invention discloses a gear tooth surface wear condition visual analysis method and system, and belongs to the technical field of monitoring analysis. After the gear stops working, wiping tooth surfaces on the two sides, away from a gear meshing position, of the gear for at least two times, scanning the tooth surfaces through first scanning equipment after the last time of wiping, and sending a first scanning image to an upper computer; when the first scanning equipment works, scanning the gear tooth side end, corresponding to the first scanning equipment, on the gear through second scanning equipment, and sending a second scanning image to the upper computer; and the upper computer analyzes and compares the difference between the stored first scanning image and a preset standard scanning image, and circles a difference area on the first scanning image. According to the method, the tooth surface wear image and the number of the tooth surface of the gear tooth can be obtained through the tooth surface and the side end of the gear tooth and analyzed with the standard scanning image, and the difference area is obtained.
Description
technical field [0001] The invention relates to the technical field of monitoring and analysis, in particular to a visual analysis method and system for gear tooth surface wear conditions. Background technique [0002] There are several types of gear tooth surface wear, such as normal wear, pitting wear and adhesive wear. In the existing wear analysis, the wear condition of the mechanical device can be obtained through the analysis of the wear particles of the oil pollution situation, the change of the wear particle coverage area index, and the tribological theory. The wear is analyzed optically. There are still many deficiencies in the linear detection of the wear condition of the split gears. The previous detection scheme is to analyze the wear particles after sampling the split gears to indirectly understand the wear of the gears. However, this analysis only indirectly predicts the wear status and cannot reflect the wear of the gear teeth. Surface wear status. Moreover...
