    Abstract: A bearing preload adjuster for a bicycle crank set and bottom bracket comprises an adjustment ring for coupling with a bicycle crank arm, a movable plunger comprising an external thread for rotatably coupling with the adjustment ring. The adjustment ring is rotated in order to cause the plunger to extend along an axis of the bottom bracket and apply pressure to a bottom bracket bearing inner race. The adjustment ring is rotated until the clearance in the bearing assemblies and the play in the bottom bracket assembly has been eliminated. This allows the crank assembly to rotate freely, while preventing the crank assembly from sliding side to side inside the bearing bores and along the axis of the crank spindle.

At the axially outer end of the ring, at the side where the flange (17) is provided, the interface surfaces between the external body (16) and the core (15) terminate in a groove (21) formed partly in the outer body and partly in the core. The groove (21) accommodates a sealing ring of polymeric material (22) which is cast and continuously covers a circular separation line (23) at the axially outer end of the interface between the core (15) and the outer body (16).

  • Patent number: 8944694
    Abstract: A bearing device for a driving wheel includes an outer race having an inner periphery in which double-row outer raceway surfaces are formed; a hub wheel and an inner race having outer peripheries in which double-row inner raceway surfaces opposed to the outer raceway surfaces are formed; and double-row rolling elements interposed between the outer raceway surfaces and the inner raceway surfaces. A shaft hole of the hub wheel is formed into a cylindrical shape, and a male spline is formed on an outer periphery of a stem section of the outer joint member so that the stem section of the outer joint member is press-fit into the shaft hole of the hub wheel. With this, recesses caused to fit on the male spline with interference are formed in the shaft hole of the hub wheel, whereby the hub wheel and the outer joint member are separably coupled to each other.

  • Patent number: 8936321
    Abstract: A flanged bearing ring for a motor vehicle wheel includes two different materials joined as a single piece: a tubular core and an outer body around the core. The outer body forms a radial flange and is made of a lighter material than that of the core. The ring further includes an element of generally tubular shape, which contacts both the outer body and the inner core to cover and seal with continuity a circular line of separation at the end of the interface surface between the core and the outer body at the axially outer side of the ring. The tubular element further forms a cylindrical axial edge which extends in an axially inner direction and is fixed in the axially outer end of the core cavity, and a cylindrical tubular portion, projecting in an axially outer direction beyond the flange, for centering the vehicle wheel.

  • Publication number: 20150010260
    Abstract: A passenger automotive vehicle wheel bearing assembly having improved impact Brinell resistance is provided. Due to a controlled gap between a rotating component and a non-rotating component or a vehicle suspension structure, the non-rotating component or the vehicle suspension structure is permitted to share impact loads caused by a sufficient radial or side impact (such as a pothole or curb impact) to the rotating component, thus preventing excessive loads from being transmitted to rolling elements, and providing greater resistance against Brinell impact damage that would generate a noise and/or vibration condition in the bearing assembly. Wheel bearing assemblies according to the invention provide increased impact Brined resistance while avoiding excessive contact between the rotating component and the non-rotating component or the vehicle suspension structure during extreme cornering maneuvers.

  • Patent number: 8915651
    Abstract: An inner ring member having multiple flange portions is formed by cold forging. A tapered surface is formed in a state of a forged surface on the inner ring member so as to gradually increase in diameter from an inner side toward an outer side in a vehicle lateral direction over a region from a position near root portions of inner side faces of the flange portions in the vehicle lateral direction to a position radially outward of an outer periphery of an outer end portion of an outer ring member in the vehicle lateral direction. A seal member is attached to the outer periphery of the outer end portion of the outer ring member. A seal lip that is in sliding contact with the tapered surface in the state of a forged surface is formed at a distal end portion of the seal member.

  • Patent number: 8915649
    Abstract: A wheel bearing apparatus has a protecting cover formed from non-magnetic steel sheet with a cup-shaped configuration. The protective cover has a cylindrical fitting portion, a disk-shaped shield portion, a radially reducing portion, a stepped portion and a bottom portion. The cylindrical fitting portion is press-fit into the inner circumference of the inner-side end of the outer member. The disk-shaped shielding portion extends radially inward from the fitting portion, via the radially reducing portion. The inner-side surface of the shielding portion is arranged close to or in contact with a rotation speed detecting sensor. The bottom portion is continuous with the shielding portion, via the stepped portion to close the inner-side end of the inner member. A full deflection of the side surface of the shielding portion that is caused by a load the same as that applied to the protecting cover when it is press-fit into the outer member is limited to a predetermined value or less.

  • Patent number: 8905645
    Abstract: A wheel bearing apparatus has an outer member, an inner member, and double row rolling elements are contained between the outer raceway surfaces. Seals are mounted in openings formed between the outer member and the inner member. A shoulder height H of the inner raceway surface of the inner ring is set with a range of 0.4-0.8 times a diameter “d” of the ball (H/d=0.4-0.8). A shoulder height ? of a smaller diameter portion formed on the outermost circumference of the inner ring is set to a value ?/d?0.35. A corner, formed by the tapered surface and the inner raceway surface, is rounded to have a circular arc cross-section. A shoulder height H1 of the inner raceway surface from its bottom to the corner is set within a range of 0.40-0.50 times a diameter of the ball (d) (H1/d=0.40-0.50).
