摘要： Damping and sealing of the quill shaft (30) that transmits torque from one rotating component to another as for example in a pitch change actuator system for aeronautical propellers is provided by an O-ring (40) mounted in the space between the end of ball screw (20) and the flange (41) radially extending from quill shaft (30) and the preload of the O-ring (40) provided by the shims (46) bearing against flange (41) and O-ring (40) which serves to enhance the wearability of splines (26, 28 and 50).
