Patent number: 11906331Abstract: An apparatus configured to measure the output of a rotary actuator unit includes a rotary actuator unit. The unit includes a stationary portion, a rotating portion, and a main rotational axis (L) that runs in an axial direction from a first end of the rotary actuator unit to a second end of the rotary actuator unit. The first end is opposite the second end. The apparatus also includes a linear position sensor comprising a follower, a sensor, and a sensor arm, wherein the follower is attached to the sensor by sensor arm; and wherein the sensor is attached to the stationary portion. The apparatus also includes a follower track attached or formed in, or on, to the rotating portion.

Publication number: 20230133770Abstract: A rotary actuator mounting system configured to attach a rotary actuator to and between two relatively moveable parts, the rotary actuator being attached to a first of the two relatively moveable parts and to a second of the relatively moveable parts such that operation of the actuator causes one of the first and second relatively movable parts to rotate relative to the other of the first and second relatively movable parts about an axis of the rotary actuator. The system includes a compliant attachment component connecting the actuator to the first relatively moveable part, the compliant attachment component having a first end attached to the first movable part and a second end attached to the actuator, and wherein at least one of the first and the second end is in the form of a ball bearing arranged to be received in a complementary socket on the actuator and/or the first movable part.Type: ApplicationFiled: November 3, 2022Publication date: May 4, 2023Inventor: Jonathan DARBY

Publication number: 20220402464Abstract: A brake device for braking rotation of an input shaft includes a selectively operable trigger brake that includes: a static element; a trigger brake shaft mounted for rotational and axial movement relative to the static element and the input shaft; a preloaded torsion spring rotationally coupled to the input shaft but permitting a limited rotational movement between the trigger brake shaft and the input shaft; a roller jamming mechanism operable upon the relative rotation between the trigger brake shaft and the input shaft exceeding a predetermined amount to stop rotation of the input shaft upon operation of the trigger brake; and a brake actuator for selectively moving the trigger brake shaft into and out of engagement with a contact surface of the static element. Engagement of the contact surface of the static element and the trigger brake shaft overcomes the preload of the torsion spring.Type: ApplicationFiled: June 9, 2022Publication date: December 22, 2022Inventors: Jonathan A. DARBY, Colin R. HARRISON

Publication number: 20220228647Abstract: A rotary geared actuator RGA includes an actuator body that has a gear or gears and means configured to rotate said gear or gears about a first central longitudinal axis X?. The RGA also includes a drive transmission shaft extending along a second central longitudinal axis X?, means for rotating said drive transmission shaft about said central longitudinal axis X?, and means for translating said rotation of said drive transmission shaft to said gears so as to cause rotation of said gears about said first central longitudinal axis X?. The second central longitudinal axis X? of said drive transmission shaft is laterally offset from said first central longitudinal axis X?.Type: ApplicationFiled: January 12, 2022Publication date: July 21, 2022Inventors: Colin R. HARRISON, Jonathan A. DARBY
