Turbocharger systems and methods
11614000 · 2023-03-28 · ·

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.

Adjustable mount for engine accessory

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.
