An apparatus for disassembling and assembling a lower vane carrier and a method for disassembling and assembling the lower vane carrier by using the apparatus are proposed. The apparatus includes a rolling jig that is mounted on the lower vane carrier mounted inside a lower turbine casing, a bolt member that passes through a region where the rolling jig and the lower vane carrier are in contact with each other, and a block member mounted adjacent to the bolt member and configured to prevent the bolt member from being separated.

A variable guide vane (VGV) described herein includes an airfoil for interacting with a fluid inside a gas path of a gas turbine engine. The airfoil is mounted to a button and rotatable with the button about an axis. The button includes a platform surface defining part of the gas path adjacent the airfoil during use. The platform surface of the button includes a depression for receiving therein part of an adjacent VGV and providing clearance between adjacent VGVs at aggressive vane angles.

A device for assembling a turbine engine is configured for centering a shaft of a second module relative to a longitudinal axis of a hollow hub placed in front of a first module, the first module including a longitudinal cavity opening at the front into the hollow hub and passing through the first module until a rear end, the shaft configured to be inserted into the longitudinal cavity. The device includes a centering element and a guiding tube. The centering element is configured to be placed in the hollow hub. The guiding tube is configured to enter into at least one portion of the longitudinal cavity of the first module. The device is arranged so that the guiding tube slides inside the centering element. The invention also relates to the assembly formed by the device and a calibration jig, as well as an assembly method using same.

A lift assembly includes an upper rail. A plurality of rail flanges extend from the upper rail. The lift assembly further includes a plurality of combustion can support assemblies spaced apart from one another. Each combustion can support assembly of the plurality of combustion can support assemblies includes a support flange slidably coupled to a rail flange of the plurality of rail flanges, an outer sleeve, and an inner sleeve assembly configured to removably couple to a combustion can of the turbomachine. Each combustion can support assembly of the plurality of combustion can support assemblies defines a cylindrical coordinate system having an axial direction, a radial direction, and a circumferential direction. Each combustion can support assembly of the plurality of support assemblies is configured to move along any of the axial direction, the radial direction, or the circumferential direction relative to the upper rail.

A turbocharger includes a center housing that includes a through bore and a stepped locating pin socket that includes a stop surface; a bearing disposed in the through bore where the bearing includes an opening; and a stepped locating pin where the stepped locating pin includes a pin portion received in part by the opening of the bearing and a seating portion secured via an interference fit in the stepped locating pin socket where a maximum radius of the seating portion exceeds a maximum radius of the pin portion and where the stepped locating pin includes a stop surface that contacts the stop surface of the stepped locating pin socket to axially position the stepped locating pin in the stepped locating pin socket.

A ducted fan engine module and method of assembling the same is disclosed. In various embodiments, the ducted fan engine module includes a ducted fan engine having a ducted fan case configured to house a fan; a lower V-blade fitting secured to a lower frame; and an upper V-blade fitting secured to an upper frame.

A support assembly for a turbocharger defining a system axis, the support assembly comprising a housing assembly and a bearing assembly. The housing assembly comprises a housing defining at least one support groove and a seal plate. The bearing assembly comprises an outer sleeve defining at least one support tab. The at least one support tab is sized and dimensioned such that, when the outer sleeve is supported by the housing member in a desired orientation, the support tab is within the support groove such that movement of the outer sleeve along the system axis relative to the housing member is inhibited. The seal plate may be configured to define at least one anti-rotation projection arranged relative to the support tab to inhibit rotation of the outer sleeve about the system axis relative to the housing member.

An adjustable mount for an aircraft engine accessory. A first bracket adapted to be coupled to the engine accessory has a first bore with a first annular bushing with a threaded radially inner surface extending through the first bore. A second bracket operatively coupled to the engine at mounting location has a second bore with a second annular bushing with a threaded radially inner surface extending through the second bore. A threaded stud extends axially through the first and second bushings and is engaged with their threaded inner surfaces. Rotation of the first and/or second bushings varies the relative axial positions of the first and second bushings on the stud, thereby adjusting an axial gap between first and second brackets. First and second nuts fastened to first and second ends of the threaded stud axially retain the mount together with the axial gap between the first and second brackets fixed.

An internal retaining ring for placement in a bore of an outer component of a rotating assembly comprises a semi-annular body having an outer circumferential surface with a curvature defined about a first center of curvature and radially outward protruding anti-rotation tabs operable for engagement with a corresponding anti-rotation feature of the outer component. An inner circumferential surface of the semi-annular body has radially inward protruding tabs circumferentially spaced apart around the inner circumferential surface. The radially inward protruding tabs have radially inner surfaces concentric with the outer circumferential surface, and recessed portions between the radially inward protruding tabs and having curvatures defined about a second center of curvature, the second center of curvature different from the first center of curvature.
