Abstract:
A cage assembly is moved in the axial direction to approach an inner ring from a small rib portion side. An inner ring assembly is constituted by causing tapered rollers of the cage assembly to climb over a small rib portion to be fitted on an inner raceway surface, and then is assembled to an outer ring. In this method, a jig is provided adjacent to the small rib portion. The jig includes recessed grooves that are formed in the outer peripheral portion of the jig and that enable contact of the respective tapered rollers. Each recessed groove has a recessed arcuate shape in cross section. The tapered rollers of the cage assembly are caused to slide radially outward along the recessed grooves, so that the diameter of cage is increased. Accordingly, the tapered rollers climb over the small rib portion to be fitted on the inner raceway surface.

Claim (Index 6):
A jig that is used to assemble a tapered roller bearing that includes an inner ring, an outer ring, a plurality of tapered rollers interposed between the inner ring and the outer ring, and an annular cage in which pockets that hold the tapered rollers are formed in a circumferential direction, the tapered roller bearing being assembled by\n moving a cage assembly, in which the tapered rollers are temporarily housed in the pockets so as not to slip off radially outward, in an axial direction to approach the inner ring from a side near a cone front face rib portion of the inner ring, constituting an inner ring assembly by causing the tapered rollers of the cage assembly to climb over the cone front face rib portion to be fitted on an inner raceway surface of the inner ring, and assembling the inner ring assembly and the outer ring to each other to obtain the tapered roller bearing, wherein the jig has an outer peripheral shape that is continuous with an outer peripheral surface of the cone front face rib portion, and including recessed grooves that are formed in an outer peripheral portion of the jig and that enable contact of the respective tapered rollers, the recessed grooves each having an inclined shape in which a groove bottom extends radially outward as the recessed groove extends toward one side in the axial direction, which is a cone front face rib portion side, and having a recessed arcuate shape in cross section.
