Abstract:
A retention method for a spherical bearing, the spherical bearing comprising an outer race and an inner race wherein a spherical surface of the spherical bearing is supported in the outer race rotatably and slidably and the outer race is retained in a race retention hole formed in a housing, the retention method comprising the steps of:forming, in the housing on an inner wall surface of a first side of the race retention hole, a screw portion having a given stroke coaxially with the race retention hole; forming, on a second side of the inner wall surface of the race retention hole, an annular groove to be retained with a snap ring; forming, on one side of a periphery of the outer race, a stepped portion having a diameter smaller than the periphery of the outer race; retaining a first snap ring, while retaining the outer race of the spherical bearing in the race retention hole, in the annular groove; and pressing an end face of the stepped portion with an end face of a setscrew toward the first snap ring by screwing and tightening the setscrew formed with a through hole in an axial direction in the screw portion, wherein the spherical bearing is retained to the housing by clamping the outer race with the first snap ring and the setscrew.
