Abstract: A system includes a permanent magnet generator (PMG) with a generator shaft defining a longitudinal axis. A brake system includes a brake shaft with a first end operatively connected to the generator shaft for selectively rotating with the generator shaft or braking to slow the generator shaft. A shear shaft is operatively connected to a second end of the brake shaft axially opposite the first end along the longitudinal axis. The brake system includes a wedge with a first position radially withdrawn from the brake shaft, and a second position radially pressed against the brake shaft for applying braking forces to the brake shaft and to the generator shaft.

Abstract: A torsion shaft assembly includes a torque carrying shaft including a driven end configured for receiving torque input to the torque carrying shaft and a driving end configured for outputting torque output from the toque carrying shaft. The torque carrying shaft includes an axial facing damping interface surface axially between the driven end and the driving end. A friction tube is disposed outboard of the torque carrying shaft. The friction tube is connected at a first axial location to be driven by the torque carrying shaft. The friction tube includes an axial facing damping interface surface that abuts the axial facing damping interface surface of the torque carrying shaft, forming a damping interface to provide frictional dampening against angular vibrations occurring as differential angular displacement between the driven end and the driving end of the torque carrying shaft.

Abstract: A generator shaft assembly including a primary shaft, a disconnect shaft housed within the primary shaft, where a first end of the disconnect shaft is configured to couple with the primary mover and a second end of the disconnect shaft is configured to mate with the generator. A retainer ring housed within the primary shaft having at least a landing and a groove on an inner surface thereof and a retainer member positioned between the landing of the retainer ring and an outer surface of the disconnect shaft configured to limit axial motion of the disconnect shaft relative to the primary shaft.

Abstract: A shaft system includes an outer shaft including an inner surface defining a conduit and an inner shaft extending within the conduit. The inner shaft includes a radially extending passage having a first end and a second end. A centrifugal force activated damper extends between the outer shaft and the inner shaft. The centrifugal force activated damper includes a first member arranged between the inner shaft and the inner surface at the first end of the radially extending passage, a second member arranged between the inner shaft and the inner surface at the second end of the radially extending passage, and a connecting member extending through the radially extending passage. Rotation of the shaft system causes the first member and the connecting member to shift away from the second member into the inner surface of the outer shaft.

Abstract: A clutch assembly includes a clutch pack, and a rotating control piston selectably engageable with the clutch pack via movement of the clutch piston along an axis of rotation of the control piston. The clutch piston includes a piston member engageable with the clutch pack, a cover plate installed into the piston member to define an enclosed volume, and an axially fixed chamber divider positioned in the enclosed volume to divide the enclosed volume into a control pressure chamber and a pressure balancing chamber. Both the control pressure chamber and the pressure balancing chamber are filled with hydraulic fluid, and the control piston is moved between a disengaged position and an engaged position via modulation of hydraulic pressure in the control pressure chamber.
