The present invention relates to a hydraulic extrusion tool for extruding a rotor shaft for a turbomachine, and a corresponding method. The turbomachine has a structure that is fastened to the rotor shaft by a press fit. The extrusion tool has a first tool part that is configured for the purpose of being arranged on a first side of the structure, and which has a coupling mechanism that is configured for the purpose of coupling the first tool part to the structure, in such a way that the first tool part and the structure cannot move away from each other, at least in one direction along an axis of the rotor shaft; and an induction device that is configured for the purpose of heating the structure by induction in the region of the press fit.

A system and method for removing and replacing fire-tubes. The system can include a powered system, a fire-tube puller coupled to said powered system. The fire-tube puller has a puller back which is coupled to a plug rest. A plug rest is approximately perpendicular to the puller back, and the fire-tube will rest upon the plug rest when the fire-tube is being removed or installed. The system can also include a stack adjuster which is coupled to the plug rest. The stack adjuster can couple to a stack so as to reposition the stack.

An extraction tool includes a coupling disc, an operating rod and two pads, wherein the coupling disc is penetrated by an assembly hole, the operating rod is provided in the assembly hole, and the pads can be movably arranged on the coupling disc. The coupling disc is penetrated by four first through grooves, two second through grooves, two third through grooves and two fourth through grooves. Each of the pads respectively covers one of the fourth through grooves, and the pads are each penetrated by one fifth through groove, each fifth through groove communicates with one of the fourth through grooves, and one side of each fifth through groove forms an alignment relationship with one of two sides of each of the fourth through grooves.

A method for jointing elements, each having a cutout, on a shaft by a device for producing a control shaft, comprises disposing the elements vertically above one another, aligned, and fixed. The method also comprises pushing the shaft in vertically from above though the cutouts of the elements by a traversable guide carriage of the device and displacing by a pneumatic piston of the device the traversable guide carriage and the shaft attached thereto until a maximum first press-in force is reached. The method further comprises displacing by at least two spindles of an electric spindle drive of the device the traversable guide carriage and the shaft when the maximum first press-in force is exceeded.

A device for manipulating a hollow shaft configured to create a pivot link between a first element and a second element. The manipulation device comprises a cylindrical body having a diameter variable by radial contraction or radial expansion of the cylindrical body, a module for controlling the diameter of the cylindrical body configured so that the diameter of the cylindrical body has alternatively at least a first diameter suitable for the cylindrical body to be displaced in the hollow shaft and a second diameter suitable for the cylindrical body to be blocked in the hollow shaft. The cylindrical body comprises an end configured to protrude from the hollow shaft when the cylindrical body is blocked in the hollow shaft. The manipulation device allows the alignment of the orifices due to the end configuration of the cylindrical body.

Sucker rods include end fittings having an outer wedge portion proximate to an open end, an inner wedge portion proximate to a closed end, and an intermediate wedge portion between the outer and inner wedges. Each wedge includes a leading edge, a trailing edge, and an angle between the leading and trailing edges. The triangular configuration, length of the leading edge, the length of the trailing edge, and size of the angle in each wedge portion cause distribution of force, such that compressive forces distributed to the rod proximate the closed end exceed compressive forces distributed to the rod proximate the open end. An automated installation procedure installs the end fitting through the use of multiple chucks, positioned by servo motors along a fitting table.

A device for jointing a plurality of elements, each comprising a cutout for a shaft, in a predetermined angular position on the shaft, may include a traversable guide carriage configured to push the shaft from above through the cutouts of the elements. The device may also include an electrical spindle drive and a pneumatic piston for displacing the traversable guide carriage.

A mounting/dismounting device for mounting/dismounting a connecting pin used for an end-to-end assembly of two frame elements includes a mounting/dismounting rod having a longitudinal axis, a head adapted to cooperate with a screwdriver, and a rod body having a proximal portion and a threaded distal portion. The device also includes a base supporting a nut and having an abutment portion shaped to bear on one of the two frame elements, the threaded distal portion being provided to be screwed into the nut, a proximal stop mounted freely in rotation on the proximal portion of the rod body, and a bushing mounted around the rod body between the nut and the proximal stop.

A tool is provided for removal and installation of a fire tube that extends into an opening in a wall of a heating vessel. The fire tube locates within an interior of the heating vessel when mounted thereto. The fire tube has a tube wall that defines a tube interior and has a mounting end for mounting the fire tube to the wall of the heating vessel. The tool has an elongated main shaft member having an insertion end and an opposite control end. A first support is mounted upon the insertion end that is configured for being closely received within the tube interior. A second support is mounted along the length of the main shaft member, the second support having a fire tube interface configured for engaging and releasably coupling to the mounting end of the fire tube. A lift coupling couples to the main shaft and locates between the second support and the control end of the main shaft member for coupling to a lift line. A counterbalance support carries removable weighting members, the counterbalance support being coupled to the main shaft by a counterbalance support spacing arm that extends laterally from the main shaft member.
