Abstract: An assembly for a coupling together rotatable components according to an example of the present disclosure includes, among other things, a rotor shaft extending along a centerline axis, the rotor shaft defining an inner bore extending from an axial end of the rotor shaft, a gear mounted on an outer diameter of the rotor shaft, a lock nut threadedly engaged with the outer diameter of the rotor shaft such that the lock nut abuts against an axial end face of the gear, and a retainer including a step portion extending from a head portion and including a projection portion extending from the step portion. The projection portion is insertable into the inner bore to bias the lock nut against the axial end face of the gear, and the step portion is dimensioned to establish an interference fit with the rotor shaft along the inner bore. A starter assembly and a method of assembly are also disclosed.

Abstract: A gearbox mounting link between a gas turbine engine structure and a gearbox mounting location comprises two engine attachment brackets secured to an engine structure, and attachment plate rotatably attached between the engine attachment brackets, and a secondary retention sleeve and fastener. The attachment plate includes a fusibly separable section configured to attach to the gearbox, a static section, and a shear necks connecting the statis section to the fusibly separable section. The secondary retention sleeve is supported by and secured to the static section. The secondary retention fastener is supported by the secondary retention sleeve, and is disposed through an oversized fastener passage through the fusibly separable section, thereby loosely retaining the fusibly separable section in at least one of the two degrees of freedom in the event of a load sufficient to break the shear necks, separating the fusible separable section from the static section.

Abstract: A mounting link between an engine and a gearbox comprises an engine attachment piece, a gearbox attachment piece, and primary and secondary retention fasteners. The engine attachment piece is rotatably secured to the engine, and the gearbox attachment piece is rotatably secured to the gearbox. The primary retention fastener rigidly constrains the gearbox attachment piece with respect to the engine attachment piece in a single degree of freedom, but is configured to shear at a breakpoint load. The secondary retention fastener constrains the gearbox attachment piece loosely with respect to the engine attachment piece, and can withstand the breakpoint load. The gearbox attachment piece and engine attachment piece abut in a friction fit that provides Coulomb damping.

Abstract: A gearbox assembly includes an outer housing and a gear box shaft at least partially disposed in the outer housing. The gear box shaft includes an interior region and a reservoir dam that separates the interior region into a reservoir volume and a spline volume. The reservoir dam has a vent hole formed therein that passes through it such that a surface of the dam is in fluid communication with a region defined by the outer housing and outside of the gear box shaft.

Abstract: A gearbox assembly for use in a gas turbine engine includes a gearbox housing and first and second shafts. The first shaft is rotatably mounted in the gearbox housing. The first shaft has a first set of splines and defines a central cavity. The second shaft has a second set of splines engaged with the first set of splines. A scupper is positioned on an inner surface of the gearbox housing proximate the first shaft so as to direct liquid from the scupper through the central cavity of the first shaft to the first and second sets of splines.

Abstract: A single drive, dual clutch accessory drive system for an aircraft including an input shaft connected to a low pressure spool of a turbine engine. The input shaft is rotatable at a first input speed and at a second input speed that is distinct from the first input speed. An output shaft is operatively connected to an aircraft accessory. A first drive path operatively connects the input shaft and the output shaft. The first drive path includes a first clutch and a gear system. The first drive path is operable to adjust the first input speed to a selected output shaft speed. A second drive path operatively connects the input shaft and the output shaft. The second drive path includes a second clutch. The second drive path is operable to rotate the output shaft at the second input speed.
