Title:
POSITION SENSING ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2010/008849
Kind Code:
A3
Abstract:
A position sensing assembly (22) includes a bearing element (62) and a helically shaped rotational member (64) used to drive a portion of a sensor assembly (60), such as a Digital Rotary Magnetic Encoder. Interaction between the bearing element and a helically shaped rotational member minimizes the presence of backlash in the position sensing assembly. Accordingly, as an actuator assembly (20) drives both a control element, such as a flight control surface (24), and the position sensing assembly, the sensor assembly generates an output signal that accurately reflects the position of the control element.
