Claims

[Claims for Utility Model Registration] (1) The tip of the rotating shaft is located inside a housing that supports the outer ring of the rolling bearing, and the rolling bearing is supported by the housing and the tip of the rotating shaft, and In the rolling bearing inspection device, the rotating shaft is supported by a radial bearing and a thrust bearing and rotated by a drive device, and the vibration generated by the rolling bearing is measured and inspected by a sensor installed in the housing. A rolling bearing inspection device characterized by having a configuration in which magnetic bearings are installed as radial bearings and thrust bearings in a non-contact manner with respect to a rotating shaft. (2) The rolling bearing inspection device according to claim (1), wherein two radial bearings are installed along the rotating shaft, and one radial bearing is a magnetic bearing and the other radial bearing is an air bearing. (3) The rolling bearing inspection device according to claim (1), wherein an air bearing is installed as the radial bearing in place of the magnetic bearing in a non-contact manner on the rotating shaft. (4) Claims (1), (2) or
(3) Rolling bearing inspection device as described.
