  • Patent number: 11584156
    Abstract: Implementations disclosed and claimed herein provide a wheel cover system. In one implementation, an inward force exerted against a wheel cover of the wheel cover assembly in an inward direction towards the hub is received. The inward force overcomes a spring bias of a spring of the receiver and translates the wheel cover assembly in the inward direction. A first rotational force rotating the wheel cover assembly in a first direction is received. The first post guides and engages the first hook, and the second post guides and engages the second hook during rotation. A first positive feedback is generated in response to the inward force and the first rotational force. The wheel cover assembly is releasably locked to the receiver by translating the wheel cover assembly in the outward direction using an outward force generated by the spring bias. The outward force provides a second positive feedback.

At a preset load limit, the extrudable ring is extruded through at least one bore in a drive piston between the head nut and the extrudable ring, to allow shank to move relative to the inner sleeve until the tensioning load is fully applied. Alternatively, a drive member is provided between the head nut or head flange and the compression ring, and at a preset limit, the compression ring allows the shank to move relative to inner sleeve until the tensioning load is fully applied. The preset limit will typically correspond to the force required to fully expand the outer sleeve.

  • Patent number: 8757919
    Abstract: A component includes a first member, a second member and a device for fastening the first member to the second member. A first hole extends through a portion of the first member and a second hole extends through a portion of the second member. The first member and the second member are positioned such that the first hole and the second hole coincide. The fastening device includes an elongated fastening element arranged in the coinciding holes and a bushing arrangement arranged around the fastening element and adapted to establish a load transmission path between the first member and the second member. A first part of the bushing arrangement is arranged such that an inner surface thereof is positioned at a distance from an exterior surface of the fastening element for establishing a first load transmission path via the bushing arrangement and bypassing the fastening element in a first load condition.

  • Publication number: 20130336716
    Abstract: Fastening system for wind turbines characterized by comprising a front flange (9) and a rear flange (8), which are joined together and supported on the hollow rotary shaft (2), and coupled to the pitch system comprising the bearings (6) for the shaft and the star-shaped part (4). The fastening method couples the rear flange (8) to the hollow shaft (2) with a tapered collar (10) and also to the front flange (9) through some spacer bushings (11). The collar (10) uses friction to transfer significant moments and axial stresses so as to improve the fastening system, and the direction of the bolts on the collar (10) and the bolts (12) on the spacer bushings (11) simplify inspection and maintenance tasks.

  • Patent number: 8496394
    Abstract: A method or arrangement for clamping at least one first and one second component to each other with a connection by force on all sides is disclosed. The connecting arrangement comprises a bolt extending from a first component through a through opening in a second component, a clamping nut which is screwed on the bolt for clamping the components, and a cone pair comprising an inner cone with a split and an outer cone. One part of this cone pair is formed as a conical clamping element, which is arranged and axially moveable for radial clamping on the bolt between the components and the clamping nut. A locking nut is screwed on the conical clamping element and clampable against an abutment surface of the second component to limit moveability of the clamping element.

  • Publication number: 20130098223
    Abstract: A quick release coupling has a first component with an axial portion terminating in a shoulder defining an abutment surface. A second component has a collar with a cavity defining an internal abutment surface and having a lateral opening to permit the collar to be laterally slid onto the axial portion such that the internal abutment surface engages the abutment surface of the shoulder to inhibit axial separation of said first and second components. An axial bolt is displaceable into a position extending between the axial portion and the collar so as to inhibit lateral movement of the collar when the collar is positioned on the axial portion. In order to release the coupling, the bolt is retracted to permit lateral displacement of the collar and thereby release of the coupling.

Each cavity extends into the joining portion from the end surface in alignment with one of the through-holes. Each fixation device includes: a bolt which extends through a respective through-hole and the corresponding cavity, and includes a nut which is embedded within the joining portion at the corresponding cavity to receive the bolt such that on tightening the nut and bolt a clamping force is exerted across the flange and the end surface to join the first and second components together. Under axial loads less than that causing bolt failure, each fixation device is deformable to remove the clamping force.
