20090016889 | Locking Sub-Assembly for Closing The Remaining Gap Between The First and The Last blade of a Blade Ring Which Are Inserted in a Circumferential Groove of a Turbomachine, and Corresponding Turbomachine - The invention relates to a closing assembly for closing the gap remaining between the first and the last blade of a blade ring that is inserted in a peripheral groove of a turbo machinery, said assembly consisting of at least two lateral parts, at least one of which can be hooked onto a projection that forms an undercut in said peripheral groove and at least one securing element, which secures the parts from coming detached from the peripheral groove. To provide a particularly reliable closing assembly, the securing element is configured as a pin, joining the parts of the closing assembly in a non-positive fit. | 01-15-2009 |
20090220345 | Closing Assembly for a Blade Ring of Turbomachinery - The invention relates to a closing assembly for closing the gap remaining between the first and last blade of a blade ring that is inserted into a peripheral groove of turbomachinery. Said assembly comprises at least two parts each of which can be hooked onto projections that form an undercut in said peripheral groove and comprises a securing element, which secures the parts from becoming detached from the peripheral groove. To provide a closing assembly for closing the remaining gap, which can be simply and cost-effectively detached and which reliably withstands high mechanical stress, the securing element is mounted to rotate about its longitudinal axis between the two parts and has a key head and a web. The web of the securing element can be positioned by rotation is such a way that to fit the parts in the peripheral groove, said parts can be displaced in relation to one another and to secure the parts from being detached from said groove, the web of the securing element can be placed against at least one lateral face of one of the parts. | 09-03-2009 |
20100115747 | MULTI-PART PIN REMOVER FOR REMOVING A PIN OR STUD FROM A HOLE OF A COMPONENT - A multi-part pin remover for removing a pin from a hole of a component is provided. A holder of the pin remover that is supported on the component is equipped with a projection that aligns the pin remover with respect to the component in order to reliably prevent any twisting of the pin when removing the pin from the hole. | 05-13-2010 |
20100166559 | ROTOR OF A GAS TURBINE - A rotor of a thermal turbomachine, particularly a gas turbine, is provided. The rotor includes a plurality of individual rotor components that are held together by a tie-bold and combined into a unit. The tie-bolt is supported by the assembly of the surrounding rotor components including the tie-bolt and the rotor disks. A hollow shaft which is made up of two tubular sections and a support wheel further support the rotor. | 07-01-2010 |
20110268564 | Gas Turbine with Securing Plate Between Blade Base and Disk - A turbine rotor is provided. The turbine rotor has a plurality of blades assembled into blade rows and arranged on a turbine disk. Each blade has a blade root arranged in a blade retaining slot of the turbine disk extending in an axial direction. A locking plate is arranged between the respective blade root and a base of the blade retaining slot, for securing blades against a displacement along the blade retaining slot. The locking plate is fixed to the turbine disk by folds. The locking plate comprises a plurality of cooling air holes for the passage of cooling medium from a cooling air feed passage. The respective blade root comprises two grooves extending substantially azimuthally in relation to a turbine axis, and the respective locking plate comprises two tongues which are arranged such that they are connected to the two grooves of the blade root for sealing. | 11-03-2011 |
20130129478 | GAS TURBINE ROTOR COMPRISING AN AXIALLY DISPLACEABLE TURBINE ROTOR SHAFT - A gas turbine rotor for a gas turbine is provided. The gas turbine rotor includes a compressor rotor shaft, a turbine rotor shaft and a coupling device frictionally connecting the two rotor shafts, wherein the coupling device is designed in such a way that the friction connection also exists when the two rotor shafts are displaced relative to one another. In this case, the turbine rotor shaft is lengthened at the end facing the compressor rotor shaft in such a way that said turbine rotor shaft overlaps with the compressor rotor shaft in the axial direction and the coupling device connects this lengthened end of the turbine shaft to the compressor rotor shaft in the radial direction. | 05-23-2013 |
20150247406 | METHOD FOR ASSEMBLING AND DISASSEMBLING A ROTOR HAVING A NUMBER OF ROTOR COMPONENTS OF AN AXIAL FLOW TURBOMACHINE AND SUCH A ROTOR - A method for assembling and disassembling a rotor having a number of rotor components of an axial flow turbomachine and such a rotor is provided. The rotor has a number of a plurality of disc-shaped or drum-shaped rotor components and at least one pin-shaped tie-rod extending through the rotor components, wherein a counter-bearing is screwed onto each of the projecting ends of said tie-rod for axially bracing the rotor components arranged therebetween. In order to achieve shorter service intervals, a connector is screwed onto the tie-rod between both counter-bearings, wherein, after the release of one of the two counter-bearings, the rotor components arranged between the connector and the other of the two counter-bearings are braced with each other by the connector. | 09-03-2015 |
20150260044 | ROTOR FOR AN AXIAL FLOW TURBOMACHINE AND DOUBLE NUT FOR CONNECTING TWO TIE-ROD ELEMENTS - A rotor for an axial flow turbomachine is provided, having a number of a plurality of disc-shaped or drum-shaped rotor components and at least one pin-shaped tie-rod extending through the rotor components, wherein a counter-bearing is screwed onto each of the projecting ends of the tie-rod for axially bracing the rotor components arranged therebetween. The tie-rod has at least two axially adjacent tie-rod elements which are each connected to one another in a detachable manner by connector. Elastic stretching characteristics of the two tie-rod elements are matched to each other such that, with the rotor components being clamped between the two counter-bearings, a clamping of the counter-bearing and the connection element and the rotor components arranged therebetween is at least partially released. | 09-17-2015 |
