Technical Field
[0001] The utility model relates to the technical field of rolling body detection, in particular to a device for detecting the movement amount of a thrust bearing rolling body. Background Art
[0002] Bearings are commonly used parts in mechanical equipment. Common thrust bearings generally consist of an inner ring, an outer ring, a cage and a plurality of rolling elements. The rolling elements are movably connected to the cage. When installing the bearing, technicians in this field need to first detect the movement of the rolling element. The movement of the rolling element generally refers to the movement distance of the rolling element from one extreme position to another extreme position in the bearing when the bearing is working. This movement is a part of the bearing clearance, which reflects the size of the gap inside the bearing and has an important impact on the normal operation and life of the bearing. The existing rolling element movement detection device consists of a bearing seat, a probe and a measuring instrument. The bearing is first placed horizontally on the bearing seat, and the measuring instrument is then fixed at the corresponding rolling element position. The rolling element is then contacted with the measuring instrument by the probe to detect the movement. However, the existing rolling element movement detection device generally fixes the measuring instrument on the instrument seat, changes the position of the measuring instrument by rotating the instrument seat, or manually stretches the axial position of the measuring instrument. The measuring instrument of this rolling element movement detection device cannot be adjusted axially, and the adjustment accuracy is not high, so it is not suitable for bearings with rolling elements of different sizes.
