  • Patent number: 10228027
    Abstract: A hydraulic power take-off, PTO, is provided for use with industrial drives. The hydraulic power take-off has a multi-position adapter that allows the PTO to be attached to a prime mover in a multitude of angularly indexed positions while maintaining a gravity-assisted drain and sump for the hydraulic fluid. The multi-position adapter is indexable to selectively block and allow for passage of oil from a tower housing to a clutch housing thus ensuring the hydraulic oil properly drains. As a result, the tower housing is also indexable which allows the PTO unit to be installed in a number of different configurations to meet the demands of the prime mover and the final application of the industrial machine.

  • Patent number: 9314910
    Abstract: Dynamical flange clamp for strengthening flange couplings or taking over the bolt forces in a loaded flange coupling, where opposite clamps (1, 2) are preloaded towards each other, contraholders (3) are fitted on one of the clamps (2), functioning as back stop to absorb the preload. When installed on a flange connection the gasket stress is kept virtually constant during the transfer of forces between the flange coupling bolts and the flange clamp. This is done without any further adjustments to the dynamical flange clamp. The dynamic flange clamp is particularly useful during bolt changes in a Hot Bolting operation.

    Abstract: A high capacity radial-fit coupling bolt (or “expanding sleeve bolt”) has a pair of tapered sleeves about a shank of a bolt to which can be applied a tensioning load. An extrudable ring, or a compression ring, is interposed between a head nut or head flange at one end of the shank, and one end of an inner sleeve. A tensioning load is applied to the shank, the inner sleeve causing the outer sleeve to expand diametrically. 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.

  • 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.

    Abstract: A pressure casing has a plurality of casing shells (10a, b) which can be connected in a pressure-tight manner in a parting plane (11) by a flange (13). The casing shells (10a, b) are pressed together with sealing effect in the parting plane (11) in the region of the flange (13) by at least one threaded bolt (19; 19a-d) which extends through the flange (13) perpendicularly to the parting plane (11). A reduced thermal loading of the threaded bolts (19; 19a-d) of the flanged joint is achieved by the at least one threaded bolt (19; 19a-d) being exposed over a part of its length towards the inner side of the casing (10).

    Abstract: A joint assembly includes a first component with a flange containing a plurality of spaced through-holes; a second component with a joining portion having an end surface which faces the flange and containing a plurality of spaced elongate cavities; and a plurality of fixation devices. 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.

    Abstract: A modular construction system includes an elongate construction element. The element has an elongate body including a longitudinal web, defining opposite first and second edges and a longitudinal first centerline, and a longitudinal first flange transverse to the web along the first edge, the elongate body defining opposite first and second ends. At the first end, a first end plate is provided that is orthogonal to the first centerline. Defined through the first end plate are a first hole on the first centerline, a second hole intermediate the first hole and the first edge, and a third hole intermediate the first hole and the second edge. The holes are preferably equispaced. For each of the holes, a cut-out is provided in the web. The cut-out allows insertion of a shaft of a bolt through the hole while accommodating the head of the bolt. First and second types of jointing element for coupling a number of elongate construction elements thereto to form a permanent or temporary structure are also described.
