    Abstract: A load limiter has a first disk for translating a first torque from an input and a second disk for translating a second torque from an output. Each of the first disk and the second disk has a ramp in which a torque transmitter, such as a ball is disposed. A first conical brake surface and a second conical brake surface disposed on the first disk or the second disk interact if the first torque and/or the second torque cause relative rotation between the first disk and the second disk.

    Abstract: A feedback torque limiter device for an actuator having an input shaft, output shaft and gear reduction for transmitting torque from the input shaft to the output shaft comprises an output torque sensor, and input torque limiter and a feedback mechanism. The output torque sensor senses actuator output torque downstream from an actuator gear reduction. The input torque limiter grounds additional torque from the input shaft when engaged. The feedback mechanism engages the input torque limiter when the output torque sensed by the output torque sensor reaches a predetermined value.

    Abstract: Volume, weight and complexity difficulties in the fabrication of torque limiters are avoided in a construction including a housing (10), a shaft (20) journalled in the housing (10) and adapted to be connected to a source (22) of rotary power, and a rotary output (28) journalled in the housing (10). A ball ramp coupling (44) is disposed within the housing (10) and includes an axially movable drive element (46) coupled to the shaft (20), a driven element (42) coupled to the output (28), a spring (52) biasing the elements (42,46) towards each other, facing ramps (61,62) in the elements (42,46) at the interface of the elements and balls (64) in the ramps. A first set of teeth (72) is carried by the drive element (46) while a second set of teeth (82) is carried by the housing (10) and aligned with the first set of teeth (72). When resistance to rotation of the output ( 28) is encountered relative movement between the elements (42,46) will occur which in turn will cause the ball (64) to move the drive element (46) axially relative to the driven element (42) causing the teeth (72,82) to engage to halt further torque transmission between the input shaft (20) and the output (28).

    Abstract: Reliability problems in a torque monitor are reduced in a simplified construction including a housing (30) journalling first and second coaxial shafts (34), (42). The second shaft (42) is mounted for axial movement within the housing (30), and a sleeve (58) has a threaded connection (56), (60) to the second shaft (42), and a spline connection (36), (62) to the first shaft (34). A switch (82), (84), is mounted in the housing (30) and a switch actuator (80) is mounted for movement towards and away from the switch (82), (84) to change the condition of the same. A shoulder (68) on the second shaft (42) may engage and drive the switch actuator (80) upon axial movement of the second shaft (42) in one direction, while a shoulder (96), (102) on the sleeve (58) may engage and drive the switch actuator (80) upon axial movement of the sleeve (58) in the one direction and relative to the other shaft (34) to provide an indication of relative movement between the shafts (34) and (42).

    Abstract: The present invention is a multipath power transmission for use in an aircraft nosewheel steering system. Two planetary gear sets, together providing the power to steer the nosewheel, have their ring gears externally meshed to balance the power delivered by each of the planetary gear sets. As a result, each planetary gear set must only be sized for fifty percent of the rated load, thereby minimizing weight and size, both of which are critical in an aircraft.
