Clutch assembly for an aircraft propulsion system gear train

A gear train for an aircraft propulsion system, the gear train comprising:

• an output shaft configured for rotation about a rotational axis;
• a clutch assembly including an integrated inner ring-shaft, an output gear, a clutch, and a clutch ball bearing,
• the integrated inner ring-shaft extending circumferentially about the rotational axis, the integrated inner ring-shaft extending between and to a first outer radial side and a first inner radial side, the integrated inner ring-shaft mounted on the output shaft at the first inner radial side;
• the output gear including an outer ring extending circumferentially about the rotational axis, the outer ring extending between and to a second outer radial side and a second inner radial side, the clutch including a plurality of clutch members, the plurality of clutch members disposed between the outer ring and the integrated inner ring-shaft, the plurality of clutch members configured to selectively couple the outer ring with the integrated inner ring-shaft, and
• the clutch ball bearing including an inner race, an outer race, and a plurality of ball bearing elements, the inner race mounted on the first outer radial side, the outer race mounted on the second inner radial side, the plurality of ball bearing elements retained between the inner race and the outer race;
• and
• an output gear roller bearing including a plurality of roller bearing elements in rolling engagement with the outer ring on the second outer radial side, the clutch assembly axially moveable relative to the output gear roller bearing;
• wherein the integrated inner ring-shaft extends between and to a first axial end and a second axial end, and the inner ring-shaft is axially retained by the output shaft at the first axial end and the second axial end.
