[0002] Bearings are a crucial component in modern machinery. Their primary function is to support rotating parts, reduce friction during movement, and ensure rotational accuracy. Bearings are categorized into rolling bearings and sliding bearings based on the frictional properties of the moving elements. Rolling bearings are standardized and serialized, but they exhibit greater radial dimensions, vibration, and noise than sliding bearings, and are also more expensive.

[0003] Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling elements and cage. According to the shape of the rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings.

[0004] There are many existing bearing processing companies, but batch-produced bearings generally have several bearings with dimensional deviations, resulting in a lower factory qualification rate for bearings. Some companies have developed some testing instruments for this purpose, but due to defects in the structural design, some testing instruments have insufficient detection accuracy or the detection process is more complicated, and can only be inspected from a single aspect, which brings certain inconveniences to the companies. How to test the speed, vibration concentricity, noise and temperature of the bearings requires a lot of manpower and material resources to complete the bearing detection work, and the detection error is large.

[0005] Therefore, a detection device is needed that uses a single control variable method to perform efficient and rapid comprehensive detection and analysis of bearings. Summary of the Invention
