  • Patent number: 11324659
    Abstract: A fitting assembly for installation in an opening in a tub shell wall of a bathing installation tub. A resilient grommet is sized to be inserted into the opening and has an interior peripheral recess defined in a wall portion, having a recess cross-sectional configuration. A fitting body has a protruding external rib having a rib cross-sectional configuration complimentary to the recess cross-sectional configuration, the rib positioned on the fitting body so that when the fitting body is inserted into the grommet, the rib is received into the recess on the grommet. The grommet and fitting are configured such that the recess and the rib are positioned behind the back surface of the shell wall when installed in the opening, and the grommet is compressed by the edge of the shell opening and pushed outwardly by the rib to lock the fitting into the shell opening.

  • Patent number: 8622353
    Abstract: A support device for a rotary drum having at least one roller capable of cooperating with the drum. At least two bearings permit the rotation of the roller about its axis of rotation. The support device has a chassis into which the bearings are secured. The chassis is mounted for pivoting about a pivotal axis substantially perpendicular to the plane passing through the axis of rotation of the roller and perpendicular to a block onto which the support device is placed. The device also includes a connector which is flexible in a given direction and rigid in the directions orthogonal to the direction of flexibility. The connector maintains the bearings on the block while permitting free pivotal movement of the chassis in such a way to permit alignment of the roller on the drum in the event of pivoting.

    Abstract: An elastomeric bearing can be incorporated into a bearing joint assembly of an undercarriage of a track-type machine. The elastomeric bearing can include a plurality of alternating elastomeric layers and metal plies that are configured to allow at least three degrees of relative rotational movement and can allow the relative rotation of roll, pitch, and yaw. The elastomeric bearing can be generally cylindrical with the elastomeric layers and metal plies being generally barrel-shaped such that the cross-section of the elastomeric layers and metal plies define an annular arc that follows an axis of revolution that coincides with a central longitudinal axis thereof.

  • 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.

    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.
