Abstract:
1. A method of assembling a double row tapered roller bearing which includes an outer ring including a first outer ring raceway and a second outer ring raceway on an inner circumferential surface thereof, a hub main body including a first inner ring raceway which confronts the first outer ring raceway and including a radially outwardly projecting flange at one end portion thereof, an inner ring that includes a second inner ring raceway which confronts the second outer ring raceway and is fitted on an outer circumferential surface of the other end portion of the hub main body, a row of tapered rollers which are provided rollably between the first inner ring raceway and the first outer ring raceway, a cage that includes a plurality of pockets for arranging the row of tapered rollers at equal intervals along a circumferential direction, and a seal ring provided on an inner circumferential surface of an end portion of the outer ring which lies on a side close to the first outer ring raceway, the method comprising: providing a subassembly member in which the cage and the first outer ring raceway of the outer ring are combined with each other; disposing a rotary member that includes a plurality of groove portions formed on an outer circumference thereof, concentrically with the outer ring so that the plurality of groove portions confront respectively inner circumferential sides of the pockets; disposing a guide member including a guide hole, above the rotary member; supplying the tapered rollers through the guide hole between the pockets and the groove portions, respectively; rotating the rotary member by a predetermined angle, after providing the sub assembly member in which the cage and the first outer ring raceway of the outer ring are combined with each other, so that the tapered rollers are pushed radially outward by raised portions between the adjacent groove portions thereby accommodating the tapered rollers into the pockets, respectively; providing the seal ring on the inner circumferential surface of the end portion of the outer ring; and assembling the hub main body together with the outer ring so that the tapered rollers are rollably disposed between the first inner ring raceway and the first outer ring raceway.
