Description

Technical Field

[0001] The invention relates to the technical field of bearing detection, and in particular to a cylindrical roller bearing surface defect detection device. Background Art

[0002] Cylindrical roller bearings, as a precision mechanical component, focus on efficiently bearing radial loads with their unique cylindrical rolling element design, showing excellent radial load-bearing capacity and perfectly adapting to high-speed operation scenarios; the internal structure of this type of bearing is exquisite, and the parallel arrangement of rollers combined with carefully designed spacers or isolation blocks effectively prevents the tilting and friction between the rollers, thereby significantly reducing the increase in torque during rotation and ensuring smooth and efficient operation; however, in the actual production and application process, cylindrical roller bearings face a challenge: when encountering static loads or impact loads, the local area of ​​the working surface Stress may exceed the yield limit of the material, causing plastic deformation and forming pits or grooves. These microscopic damages not only hinder the smooth rotation of the bearing, but also due to the high finish of the bearing surface, it is difficult to quickly identify and locate these problem areas with the naked eye. Especially on the inner surface of the bearing, detection is particularly difficult and often requires the use of auxiliary light sources such as flashlights, which is time-consuming and laborious. What is more serious is that although there are large-scale high-tech detection equipment on the market that can accurately diagnose such problems, their high purchase and operation and maintenance costs are a considerable burden for many companies, limiting their popularization and application in a wide range of industrial scenarios.
