<P>PROBLEM TO BE SOLVED: To provide a rolling bearing device which can improve rigidity and rotational accuracy. <P>SOLUTION: A rolling bearing device 10 includes a first rolling bearing 1A including an inner ring 3a, an outer ring 5a, rolling elements 7 arranged between them, and a retainer 9 holding the rolling element 7; a shaft 13 glued in such a state that it is fit into the inner ring 3a; and a sleeve 23 having a fitting hole 25 glued in such a state that the outer ring 5a is fit. The inner ring 3a and the outer ring 5a have an inner ring thick section 31a and inner ring thin section 32a, and an outer ring thick section 51a and an outer ring thin section 52a adjacently in axial direction, respectively, and have an inner ring rolling surface 37a and an outer ring rolling surface 57a near a step formed between the inner ring thick section 31a and the inner ring thin section 32a, and near a step formed between the outer ring thick section 51a and the outer ring thin section 52a, respectively; and an adhesive is applied between the inner circumferential surface at the inner ring thick section 31a side and the peripheral surface of the shaft 13, and between the peripheral surface at the outer ring thick section 51a side and the fitting hole 25 of the sleeve 23. <P>COPYRIGHT: (C)2013,JPO&INPIT |
