  • Ball bearing inspection device and inspection method
    Patent number: 10180376
    Abstract: A ball bearing inspection device includes: an arbor supporting an inner ring on the outer circumferential surface; a rotary drive unit driving the arbor; a first pressing unit applying a preload to a ball bearing; a second pressing unit applying a preload in an opposite direction of the pressing direction; and a vibration detection unit detecting vibration from the ball bearing. The arbor includes an abutting section that protrudes outward from the outer circumferential surface, a movable flange arranged apart from the abutting section, and a flange drive mechanism switching the movable flange between a first state in which the movable flange protrudes from the outer circumferential surface and a second state in which the movable flange is accommodated within the arbor. The flange drive mechanism is additionally provided with a drive force supply unit that applies drive force for switching to the first or the second state.
