Description

Technical Field

[0001] The utility model relates to the technical field of bearing detection, in particular to a rolling bearing self-aligning performance test platform. Background Art

[0002] Rolling bearings are precision mechanical components that convert the sliding friction between the rotating shaft and the shaft seat into rolling friction, thereby reducing friction losses. Rolling bearings need to undergo multiple inspections before leaving the factory to ensure their quality. The self-aligning performance is the ability of the rolling bearing to still work normally when the shaft centerline of the rolling bearing is tilted relative to the centerline of the bearing seat hole. Therefore, the self-aligning performance test of rolling bearings is very important.

[0003] The Chinese patented spherical roller bearing radial runout detection device with publication number CN208907798U pushes the roller on the connecting rod to fit on the outer ring of the spherical roller bearing through a first spring arranged in the cavity. When a protrusion appears on the outer ring of the spherical roller bearing, it pushes the connecting rod to move in the cavity, and then the roller is re-fitted on the outer ring of the spherical roller bearing under the push of the first spring, so that the roller will not affect the rotation of the outer ring of the spherical roller bearing due to resistance, resulting in a larger error in the detection result; however, the device cannot detect the bearing from multiple angles, and the data measured during the detection is relatively simple, and it is difficult to obtain multi-faceted data to reflect the comprehensive situation of the bearing.
