摘要： An actuator pressure intensifying assembly includes a mode valve and a gear motor assembly, the mode valve arranged to receive, at an input port, a supply pressure and to provide, at an output port, a control pressure to an actuator, the mode valve further configured to move, in response to the supply pressure exceeding a predetermined activation threshold, from a first mode in which the supply pressure flows directly from the input port to the output port in a first fluid flow path, and a second mode in which the supply pressure flows from the input port to the output port in a second fluid flow path which includes the gear motor assembly between the input port and the output port which intensifies the supply pressure such that the control pressure is higher than the supply pressure.

摘要： A twin-disc tribometer assembly includes a first sample drive shaft arranged to receive a first sample disc and a second sample drive shaft arranged to receive a second sample disc; a first drive motor configured to rotate the first drive shaft and a second motor arranged to rotate the second drive shaft. The first and second drive shafts are configured to be positioned relative to each other such that a sample disc mounted on the first drive shaft will make a point contact with a sample disc on the second drive shaft as the drive shafts rotate. The assembly is configured to allow the shafts to rotate relative to each other in a non-continuous reciprocating motion or a non-collinear motion where one sample disc is tilted with respect to the other.

摘要： An actuation system for a control surface for an aircraft includes a first, second, third and fourth actuator, a first and second bell crank, and at least one push pull rod system. Each of the first and second bell cranks comprises a first and a second crank arm, the first and second crank arms intersect with and are joined to each other at an intersection, the first and second crank arms extend from the intersection at an angle to each other, the first bell crank is pivotally connected to the sub-structure by a first pivot extending through the first bell crank's intersection, and the second bell crank is pivotally connected to the sub-structure by a second pivot extending through the second bell crank's intersection.

摘要： A strain wave gear mechanism includes: a casing; an elliptical drive shaft; an outer ring arranged coaxially around the elliptical drive shaft and rotationally fixed to the casing, the outer ring having a toothed inner circumference; a flexible ring mounted around the elliptical drive shaft radially inwards of the outer ring, the flexible ring having a toothed outer circumference. Rotation of the elliptical drive shaft causes elliptical rotation of the flexible ring relative to the outer ring such that teeth of the flexible ring engage with teeth of the outer ring at points corresponding to the major axis of the ellipse of the drive shaft to cause movement of the flexible ring in a direction opposite to rotation of the drive shaft. The outer ring is rotationally fixed to the casing via a solenoid operated disconnect gear configured to selectively disconnect the outer ring from the casing.

摘要： An actuator system includes a motor and an actuator positioning member to be driven by the motor from a start position to an actuated position. The system also includes a harmonic drive assembly between the motor and the actuator positioning member arranged to transfer torque from the motor to the actuator positioning member at a gear ratio of greater than 1:1. The system further includes means for disconnecting the harmonic drive assembly in response to failure of the motor and/or torque transfer such as to allow the positioning member to return to the start position.
