Problems solved by technology
[0002] The detection of the radial clearance of the bearing cage directly affects the clearance and fit between the cage and the rolling elements, and affects the service life of the cage, which in turn affects the service life of the bearing. The unqualified products of the cage are eliminated to ensure the quality of the product. At the same time, it prevents the outflow of unqualified products. Before the importance of the radial clearance of the cage was not recognized, the economic loss caused by the damage of the cage and the bearing damage was very large every year.

Embodiment Construction
[0009] A support rod 5 is connected to one side of the base 1, and a dial gauge 2 is connected to the other end of the support rod 5. The bearing is positioned on the base 1 through the bearing inner ring 4 and the bearing positioning block 6, and the measuring head of the dial gauge 2 Adjust the surface of the bearing cage 3.
[0010] The measurement method is: push and pull the outer ring of the bearing, drive the rolling elements and the bearing cage 3 to move through the outer ring, ensure that the force is stable during the pushing process, the direction of the force is in line with the tip of the dial indicator, and the maximum value displayed by the dial indicator Subtracting the minimum value is the radial clearance of the bearing cage 3.

The invention relates to a radial internal clearance detection device for a bearing retainer. One edge of a substrate is connected with a supporting rod, the other end of the supporting rod is connected with a dial indicator, the measurement head of the dial indicator is abutted against the bearing retainer, and a bearing is fixed on the substrate through a bearing inner ring and a bearing positioning block. The device has the advantages of being simple in structure, convenient in regulation and the like.
Description
technical field [0001] The invention belongs to the field of bearing measurement, in particular to a radial clearance detection device for a bearing cage. Background technique [0002] The detection of the radial clearance of the bearing cage directly affects the clearance and fit between the cage and the rolling elements, and affects the service life of the cage, which in turn affects the service life of the bearing. The unqualified products of the cage are eliminated to ensure the quality of the product. At the same time, it prevents the outflow of substandard products. Before the importance of the radial clearance of the cage was not recognized, the economic loss caused by the damage of the cage and the bearing damage was very large every year. Contents of the invention [0003] In order to overcome the disadvantages of the prior art, the invention provides a radial clearance detection device for a bearing cage. [0004] The technical solution adopted by the present in...
