Abstract
A method of producing a wheel bearing apparatus includes: performing positioning of a slinger of a sealing device with respect to a base shaft portion of a hub spindle by pressing a jig to press-fit the slinger to the base shaft portion, using an inner ring contacted surface, which is a step portion between a small-diameter shaft portion and a large-diameter shaft portion of the hub spindle, as a reference surface; and fitting, after the slinger is press-fitted to the base shaft portion, an inner ring to the small-diameter shaft portion such that the inner ring reaches a position at which the inner ring comes into contact with the inner ring contacted surface, in a state where an outer ring, rolling elements, and the sealing device have been assembled to the hub spindle.
Claims4
A method of producing a wheel bearing apparatus, the wheel bearing apparatus including:
- a hub spindle including a flange to which a wheel is attached, the flange being at an outboard-side end portion of the hub spindle in a vehicle-width direction, the hub spindle including a base shaft portion located at a root of the flange, a large-diameter shaft portion, and a small-diameter shaft portion, and the base shaft portion, the large-diameter shaft portion, and the small-diameter shaft portion being arranged in this order in a stepwise manner from the flange toward an inboard side in the vehicle-width direction;
- an inner ring fitted to the small-diameter shaft portion, the inner ring being brought into contact with an inner ring contacted surface that is a step portion between the small-diameter shaft portion and the large-diameter shaft portion;
- an outer ring disposed radially outward of the large-diameter shaft portion and the inner ring so as to be concentric with the large-diameter shaft portion and the inner ring;
- double-row rolling elements rollably disposed between the large-diameter shaft portion and the inner ring, and the outer ring;
- and
- a sealing device including a slinger that is press-fitted on an outer peripheral surface of the base shaft portion and a sealing member that is press-fitted on an inner peripheral surface of the outer ring, the sealing device being disposed between the base shaft portion and the outer ring, and the sealing device being assembled to the base shaft portion and the outer ring,
- the method comprising:
- performing positioning of the slinger on the outer peripheral surface of the base shaft portion by pressing a jig to press-fit the slinger to the base shaft portion, using the inner ring contacted surface as a reference surface;
- and
- fitting, after the slinger is press-fitted on the outer peripheral surface of the base shaft portion, the inner ring to the small-diameter shaft portion such that the inner ring reaches a position at which the inner ring comes into contact with the inner ring contacted surface, in a state where the outer ring, the rolling elements, and the sealing device have been assembled to the hub spindle.
