FLEXIBLE COUPLING/LINKAGE FOR AN ACTUATOR

WIPO Patent Application WO/2013/032837

A3

A flexible coupling linkage (14) anchors a housing (16) that at least partially encloses a rotor (18) of an actuator (22) against rotation, while allowing free movement of the housing (16) in two other planes relative to the rotor (18) to match an angular rotational plane orientation of the rotor (18) to prevent binding between the housing (16) and the rotor (18) due to misalignment. The flexible coupling linkage (14) can be selected from a group of pivot joints (24a, 24b) including at least one of a pivot pin joint (30, 34), a ball-and-socket joint (32), and any combination thereof. The pivot joint (24) defines a restrained point (26a, 26b) associated with the housing (16) radially spaced from an axis of rotation of the rotor (18) preventing rotation of the housing (16) about the axis of rotation of the rotor (18), while allowing angular displacement of the housing (16) about the restrained point (26a, 26b) permitting the housing (16) to match an angle of the rotor (18) to prevent binding between the housing (16) and the rotor (18).
