Abstract

The invention relates to the technical field of fault detection, particularly relates to a bearing anomaly detection method and device based on image processing. Firstly, a selected bearing image is ensured to meet a definition requirement; the bearing image is divided to obtain an inner ring image, an outer ring image and a rolling body image; whether the inner ring boundary and the outer ring boundary are concave-convex or not is checked; whether the circle centers of the inner ring and the outer ring are consistent or not is judged, whether the number of the balls in the rolling body imageis consistent with the number of the balls of the actual bearing or not is judged to serve as the detection basis of bearing abnormity, a judgment conclusion is given for reasons causing the bearing abnormity in a classified judgment and step-by-step troubleshooting mode, and the fault positioning efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of fault detection, in particular to a bearing abnormality detection method and device based on image processing. Background technique [0002] Rolling bearings are mechanical standard parts used to support journal components and sometimes to support rotating parts on shafts. A typical rolling bearing consists of an inner ring, an outer ring, rolling elements and a cage. The inner ring and the outer ring are assembled with the journal and the housing hole respectively. In most cases, the inner ring rotates with the shaft, and the outer ring does not move; but there are also cases where the outer ring rotates, the inner ring does not rotate, or the inner and outer rings rotate at different speeds. The rolling elements change the sliding friction between relative moving surfaces into rolling friction. According to the requirements of different bearing structures, the rolling elements include rolling balls, c...
