  • Patent number: 5443438
    Abstract: An assembly for transferring rotation from a centrifuge drive system to a centrifuge rotor includes a hub that is connected to the drive system for rotation about an axis. A sleeve member is attached to the hub in a position to support the centrifuge rotor. The sleeve member is formed of a material having a low coefficient of friction and is positioned to reduce the likelihood of rotor-to-hub lock. The resistance of the sleeve member to wear and to the absorption of foreign matter are also important in the selection of a material for forming the sleeve member. An acetal-based compound is preferred. By connecting the sleeve member to the hub such that the exterior surface of the sleeve member is raised relative to the surface of the hub, rotor-to-hub contact is reduced, thereby further reducing the risk that the rotor and the hub will become locked to one another.

This further circumferential clearance is smaller than that between the two sets of teeth of the damper plate and the hub themselves. In addition, the set of teeth on the hub is extended axially so that it can mesh with the teeth on both the damper plate and the ring.

    Abstract: A torsional vibration damper in which the hub ring and the flyring are interconnected through vulcanized-in basic resilient elements as well as resilient units made of rubber that are uniformly distributed around the circumference. These consist of columnar first and second resilient elements which at their outer surfaces merge into one another and at their inner surfaces are spaced from one another. The second resilient elements are precompressed by the first resilient elements and, when the torsional vibration damper is not rotating, are spaced at their outer surfaces from the inner surface of the flyring. At a desired speed of rotation, they are caused by centrifugal force to bear immovably on the inner surface of the flyring. This mechanical connection places their spring action in parallel with the spring action of the basic resilient elements.

  • Patent number: 4378220
    Abstract: An apparatus is provided for transferring torque from one shaft to another. The shafts (11) and (12) are coupled together using a flexible member, such as an elastomeric spring or belt (23), trained around pins (21) eccentrically mounted on at least two planet gears (19). A sun gear (15) which is connected to one of the shafts (11) meshes with the planet gears. These gears (19) are also connected to the other shaft, (12), either through a ring gear (66) or pivots (27). When one of the shafts is rotated, this causes the planet gears (19) to rotate, and this rotation moves the pins (21) in an arc. This gradual controlled movement of the pins (21) causes the belt (23) to stretch in a manner so that as torque is transferred from one shaft to the other, troublesome torsional vibrations are effectively damped.This energy-absorbing, torque cushioning apparatus is particularly suited for use as a lock-up clutch in motor vehicles.

  • Patent number: 4344515
    Abstract: The disclosure relates to a claw clutch mechanism, comprising opposing, interengaged clutch halves, each having axially projecting claws extending into the other. Cylindrical elastic bumpers are interposed between adjacent claws to absorb shock and accommodate axial displacement of the clutch halves. The clutch halves are of pressure cast aluminum construction, formed to provide large radius transitional fillets or roundings at the base of the claws, which correspond in radius to the contours of the cylindrical elastic bumpers. Integral reinforcing rings connect the angularly arrayed claws of each clutch half, both on the outside and the inside of the claws, to provide mechanical support for about half the length of the claw. The reinforcing rings also serve to confine the elastic bumpers, and may be provided with opposed flat surfaces at positions corresponding to bumper locations.

  • Patent number: 4331004
    Abstract: A coupling for uniformly transmitting torque from a first shaft to a second shaft while accommodating angular and/or axial misalignment between the axes of said first and second shafts. The coupling comprises a first annular member adapted to be fixed to the first shaft, a second annular member adapted to be fixed to the second shaft, a third intermediate member including an annular portion disposed between the first and second annular members and first and second pairs of elongated generally parallel arm portions operatively associated with the first and second annular members respectively.
