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, 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 with respect to 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 to 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.
