Abstract: A release bearing includes a rolling-contact bearing having a non-rotatable inner ring, a rotating outer ring, and plural rolling members located between the inner and outer rings, An adjustment ring having a ring flange is provided for abutment against a disk spring of a clutch mechanism, and a sliding element made of bearing material is disposed in a support zone defined between complementary calotte-shaped portions of the outer ring and the adjustment ring so that the adjustment ring and the outer ring are movable relative to one another for effecting a self-adjustment of the release bearing.

Abstract: The rolling bearing 1 of this bearing assembly is of the relubricatable type and is mounted tightly on the shaft 4 by its inner race 2 in such a way as to be prevented from rotating and translating on the shaft, the latter for this purpose comprising a thrust shoulder 3. The outer race 6 of the rolling bearing is housed in a ball swivel with a spherical outer peripheral surface consisting of two half ball swivels 7 back to back and this ball swivel is itself mounted in the spherical housing 8 of a support consisting of two flanges 9, 10 arranged facing one another and slightly separated from one another in the axial direction prior to clamping. One 9 of these flanges may be fixed by lugs 11 to the structure of the craft and the other flange 10 may be fixed to the previous one using screws 12.

Abstract: Balls are supported between the spherical inner race 5 and the outer race 6 which surrounds one potion of the inner race 6 through the resiliently transformable shell-like retainer 7. By making the inner race 5 and outer race 7, which influence the bearing precision greatly, to be formed in a unit respectively, the bearing precision is increased. For reference, although the retainer is divided, the retainer 7 bears merely the ball holding function and its transformation and the position relation in assembling state do not influence the bearing precision.

Abstract: A large chamfer on the outer race mates with a matching angled step in the housing bore and eliminates the need for the press fit while still meeting the application requirements. Alternative designs reduce the rotational effort and torque variation of the system and facilitate assembly. The mating tapers give the bearings freedom to self-align and thereby avoid common "clicking" noise.

Abstract: An assembly includes an overrunning clutch, a rolling bearing and a casing supporting them. An overrunning clutch-supporting portion of the casing has inwardly protruding portions that inter-engage with raised portions on an outer ring of the overrunning clutch in the direction of rotation of the outer ring. As a result, a clearance is defined between the inwardly protruding portions of the overrunning clutch-supporting portion and the raised portions of the outer ring. The overrunning clutch is automatically centered to a rotation shaft when used. An elastic ring is interposed in a predetermined compressed state between the outer ring and the overrunning clutch-supporting portion. Frictional resistance is produced between the outer ring and the overrunning clutch-supporting portion preventing the overrunning clutch from becoming shaky in the casing. The overrunning clutch is pressed against the casing by a spacer to produce the same frictional resistance between the overrunning clutch and the casing.

Abstract: An improved self-centering bearing assembly for clutch release mechanism includes a radial bearing with a rotatable inner and non-rotatable outer race. The outer race is resiliently held for radial self-centering movement by an attachment member which mounts the bearing assembly to a plastic carrier of the clutch release mechanism. The resilient element that allows self-centering is compressed between a radial flange of the attachment and a face of the outer race. When removed from the carrier, the resilient element expands sufficiently to bias the radial flange into a radially extending portion of a declutching finger contacting member rigid to the inner race. This retains the attachment member to the bearing as a separately handled, rattle-free unit.
