Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a ball bearing detection equipment. Background Art

[0002] Ball bearings are a key mechanical transmission component, mainly composed of four basic elements: balls, inner rings, outer rings and retainers. Balls and rings are usually made of high-chromium steel with high hardness, while the retainer may be made of metal or non-metal with low hardness. The main function of ball bearings is to determine the relative position of two parts (such as shafts and bearing seats), ensure that they can rotate freely, and transmit loads between them. At high speeds, the excellent performance of ball bearings can achieve free rotation with almost no wear. The importance of ball bearing detection is self-evident. First of all, bearings are the core components in mechanical transmission systems, and their performance directly affects the stability and reliability of the entire system. Any minor defects or faults may cause serious impact on the operation of the entire system, and even cause safety accidents. Therefore, strict testing of ball bearings is a key step to ensure that their performance and quality meet the standards. In the detection of ball bearings, hardness is a crucial parameter. Hardness not only determines the wear resistance and service life of the bearing, but also directly affects its load-bearing capacity and operating stability. If the hardness of the bearing is insufficient, it is easy to wear and deform during operation, thus affecting its performance. Therefore, hardness testing of ball bearings using a hardness tester is an important means to ensure their performance and quality.

[0003] When an existing hardness tester fixes a ball bearing, due to the annular shape and smooth surface of the ball bearing, traditional fixtures may have difficulty providing sufficient friction to ensure stable clamping, which may cause the ball bearing to move slightly or rotate during the hardness test, thereby affecting the accuracy of the measurement results. Utility Model Content
