TESTING DEVICE OF THIN THICKNESS LARGE SIZE BEARING

摘要

PROBLEM TO BE SOLVED: To provide a testing device of a thin thickness large size bearing capable of easily and accurately installing a thin thickness large size bearing to be a testing object and capable of performing a performance evaluation test by inclining the installed thin thickness large size bearing to an arbitrary posture.SOLUTION: This testing device 1 of a thin thickness large size bearing includes: a surface board 2 on which a bearing 60 of a thin thickness large size to be a testing object can be installed; a surface board support mechanism 3 for supporting the surface board 2 to be able to incline around a tilting center axis 12; an angle change drive device 4 for changing an inclination angle of the surface board 2; and a bearing rotation motor 52 for rotating an inner ring of the bearing 60. The surface board support mechanism 3 and the angle change drive device 4 can change the surface board 2 across a horizontal posture, a perpendicular posture, and an inclined posture. A bearing installing mechanism 6 for installing an outer ring of the bearing 60 in a fixed state with the bearing 60 mounted on the surface board 2 is provided on the surface board 2.
