  • Publication number: 20110291506
    Abstract: Centrifugally decoupling mechanical bearing systems provide thin tensioned metallic ribbons contained in a support structure. This assembly rotates around a stationary shaft being centered at low speeds by the action of the metal ribbons. Tension springs are connected on one end to the ribbons and on the other end to the support structure. The ribbons pass through slots in the inner ring of the support structure. The spring preloading thus insures contact (or near-contact) between the ribbons and the shaft at rotation speeds below the transition speed. Above this speed, however, the centrifugal force on the ribbons produces a tensile force on them that exceeds the spring tensile force so that the ribbons curve outward, effectively decoupling them from mechanical contact with the shaft. They still remain, however, in position to act as a touchdown bearing in case of abnormally high transverse accelerations.

  • Publication number: 20110026862
    Abstract: The present invention refers to a reaction rod arrangement for a vehicle including a bushing. The bushing comprises a rigid core member having a bearing portion and defining a longitudinal axis. An elastomer body is arranged on at least a portion of a radially outer surface of the bearing portion. The bearing portion comprises a first tapering portion tapering towards one axial end of the bearing portion and a second tapering portion tapering towards an opposite axial end of the bearing portion. An axial extension of the bearing portion is larger than a maximal radial extension with respect to the longitudinal axis. The elastomer body is movably arranged on the bearing portion to perform a rotational movement about the longitudinal axis relative to the rigid core member and a tilting movement about an axis perpendicular to the longitudinal axis relative to the rigid core member.

  • Publication number: 20100101052
    Abstract: A multi-link hinge for a door includes a fastening element that is securable to a furniture body. A pivotable door bearing is movable with respect to the fastening element. The pivotable door bearing defines an opened position, a closed position, and a pivot range between the opened position and the closed position. Several levers are connected to one another in a scissored arrangement. The levers connect the fastening element to the pivotable door bearing. A spring is operably disposed between the fastening element and the pivotable door bearing. The spring is pre-tensioned to bias the pivotable door bearing into the closed position. A linear damper is operably disposed between the fastening element and the pivotable door bearing. The linear damper dampens a closing movement of the door bearing. The multi-link hinge may be employed to prevent slamming of refrigerator doors, for example.

  • Patent number: 7464619
    Abstract: An operator suitable for opening and closing casement windows includes a housing (e.g., a base and a cover), and an operator arm subassembly driven by a worm. The operator arm subassembly may include at least one operator arm pivotally disposed in the housing via a flanged bearing. The operator arm may define a gear. If a plurality of operator arms are present, a sun gear may be used. The flanged bearing properly aligns the components to reduce stresses encountered during use. The flanged bearing may have a base portion, a middle portion, and an upper portion in a stepped configuration. The base may engage the base of the housing. The upper portion of the bearing may engage a cover of the housing. A middle portion of the bearing pivotally joins the arm and/or sun gear. The instant flanged bearing provides a smoother, more efficient operation and increases the useful life of the operator.

  • Patent number: 7390126
    Abstract: An idler arm bracket bearing includes a plurality of inwardly extending fingers to contact the bracket. The fingers deflect toward the bearing body as the fingers contact the bracket, thereby ensuring a full contact fit that provides a tighter joint assembly. Rib members are located between the fingers to center the bracket and limit the resilient deflection of the fingers.

  • Patent number: 7182517
    Abstract: An anti-vibration device for a motor bearing at least comprises an axial barrel core, a shaft and a shock retard piece. The axial barrel core has a recess at the bottom thereof with the recess having a flat top. A bearing is received in the axial barrel and the shock retard piece is placed on the top of the recess so that a space is formed between the shock retard piece and the recess available for the shock retard piece being deformed. The shaft is movably attached to the barrel core to contact with shock retard piece. When the shaft rotates, vibration can be retarded to allow the shaft providing a steady rotation by way of support of the shock retard piece.

  • Patent number: 7077573
    Abstract: A bearing adapted to support and allow controlled relative movement with an opposed bearing surface. The bearing is constructed to have a long life by incorporating a surface that addresses many causes of friction and wear. The bearing includes a plurality of support members extending from a base. Together, the plurality of support members can support a load applied to the base through an opposed bearing surface. Additionally, the plurality of support members allow sliding modes of motion between the opposed bearings. These support members can move independently to accommodate irregularities located between the support member and the opposed bearing, such that plowing is reduced and wear to the bearings is minimized. The support members may also be configured to allow certain non-sliding modes of motion between opposed bearing surfaces while resisting other non-sliding modes of motion.
