A tool for removal of a bushing (such as a bushing of a variable stator vane assembly of a compressor) is provided. The tool includes a cylindrical housing, a lead screw, a threaded nut, and a pulling module with puller arms to engage the bushing. The housing defines a longitudinal axis along which the lead screw extends. The lead screw is rotatably secured within the cylindrical housing by a threaded nut engaged with the lead screw. The pulling module is removably attached to the threaded nut, such that the lead screw passes through the threaded nut before passing through the pulling module. The pulling module is provided with a pair of oppositely disposed puller arms, and each puller arm is provided with a hook portion having an engagement tab configured to engage a respective notch on the bushing. A method of removing the bushing using the tool is also disclosed.

Aspects of the present disclosure deal with a tool for removing shaft components from a shaft. In one embodiment, the tool is a shaft component separator with an inflatable bladder configured to wrap circumferentially around a shaft. In one embodiment, the bladder is slotted to form a C-shaped profile so that a user can position the bladder perpendicularly around the shaft, adjacent a removable shaft component. Extending from the bladder is an inflation stem, which enables the user to move the ring between a deflated state and an inflated state via the introduction and/or removal of a fluid. Typically, the user positions the bladder between a fixed component and the removable shaft component, such that the fixed component and removable shaft component form a sandwich arrangement with respect to the bladder. Expansion of the bladder, via fluidic pressure, applies increasing axial force to the removable shaft component until the removable shaft component breaks free from the shaft.

A puller includes a first claw and a second claw arranged opposite to each other. The first claw includes a first pulling part, a first limiting part and a first connecting part. The first limiting part includes a first body part, a first notch part and a second notch part. The second claw includes a second pulling part, a second limiting part and a second connecting part. The second limiting part includes a second body part, a third notch part and a fourth notch part. A size of the second pulling part is smaller than or equal to a size of the second notch part.

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.

A method of disassembling a surgical instrument includes obtaining a surgical instrument including a housing, an input shaft defining an axis and extending from the housing, and a paddle engaged with the input shaft and configured to pivot about the axis. The method further includes disengaging a cover plate of the paddle from a body of the paddle by providing a force to the cover plate substantially in a direction parallel to the axis and disengaging the body from the input shaft by providing a force to the body substantially in a direction parallel to the axis.

The blade of a fan of a gas turbine engine situated within an intake duct is removed using apparatus including a support structure supporting a cantilevered platform for an operator and a guide rail which is profiled to receive a blade root of the blade. The operator releases the blade and slides it from its recess in the fan disc into a complementary guide channel in the guide rail. The guide rail follows a path which constrains the blade to move in a direction, and at an orientation, which avoids interference with the intake duct.

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 of 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 induction in the region of the press fit.

A system for disengaging a drive shaft from a bearing support. An assembly formed by the drive shaft and the bearing support is placed above a cylinder, which pushes on the drive shaft by passing by the central hole of the bearing support. The bearing support is driven upwards, but is blocked by a first and a second force transfer device, which allows the drive shaft to be disengaged from the bearing support.

A component forming machine with jammed component mitigation. In some examples, the component forming machine can include a platform configured to receive a lower die that supports a plurality of components for forming and includes a void through which at least some of the plurality of components pass subsequent to the forming, a die press positioned above the lower die and configured to lower an upper die to exert downward pressure on the plurality of components to form unformed components and formed components, and a separation system. In some examples, the separation system is configured to interact with the lower die to permit the formed components to fall into the void and prevent the unformed components from falling into the void.

An extraction tool for extracting a shim located in a turbomachine and provided with a through-hole, includes an extractor pin configured to be inserted into the through-hole of the shim; a first gripping member with a first distal end intended to be positioned opposite the through-hole on a first side of the shim and arranged to retain a first end of the extractor pin; and a second gripping member including a second distal end intended to be positioned opposite the through-hole on a second, opposite side of the shim, and arranged to retain a second, opposite end of the extractor pin, after the extractor pin has been inserted into the through-hole of the shim.
