摘要： A radial torque limiter, for example, for a geared rotary actuator (1, 1') including input member (S, 8) coupled to an output member (3 or 3') driving a sun gear (4) and planet gears (5) through axially projecting tabs (3g). Roller elements (2) are arranged at ramp sections (3a, 3b, 3c, 3d, 8a, 8b, 8c, 8d) formed at the input member (S, 8) and output member (3 or 3') for radially outwardly displacing the beam spring portions of the output member (3 or 3') to radially apply braking force between an external surface (14) of the beam springs and an internal surface (13) of a grounded reaction member (12) so as to brake the input member (S, 8) and output member (3 or 3') upon an occurrence of an excess transmitted torque.

摘要： A ram air turbine assembly includes a spacer that controls axial movement of a bearing assembly supporting rotation of a driven shaft to limit compression of a bearing biasing member. A gearbox includes mating gears that transfer power through a strut to a generator. Bearings support rotation of the driven shaft and the biasing member generates a biasing load to maintain desired alignment between the mating gears. Axial thrust reversals generated during operation are prevented from fully compressing the biasing member by a spacer that defines a minimum compressed height and that further limits axial movement of the bearing assembly responsive to the thrust reversals of the driven shaft.
