A drive system for an actuator comprises first and second motors, and first and second input shafts connected to be driven by the respective first and second motors. Each of the first and second input shafts comprises a first overrunning clutch configured to rotate with the input shaft in a first direction, and a second overrunning clutch configured to rotate with the input shaft in a second direction. A first drive gear is configured to be driven by either one of the first overrunning clutches, and a second drive gear is configured to be driven by either one of the second overrunning clutches, and an output clutch and an output shaft are arranged to be driven by the first drive gear in a first mode of operation of the drive system and be driven by the second drive gear in a second mode of operation of the drive system.

Dual motor drive system for actuator

A splined coupling comprises a radially inner shaft and a radially outer shaft having a cavity for receiving the inner shaft. First splines are provided on a radially outwardly facing surface of the inner shaft. Second splines are provided on a radially inwardly facing surface of the cavity of the outer shaft. The first splines are slidably engaged with the second splines. At least one biasing element, for example a diaphragm is arranged to act between the radially inner and radially outer shafts for locating the first splines in a desired axial position relative to the second splines and to provide a biasing force resisting the axial movement of the first splines relative to the second splines upon relative axial movement of the inner and outer shafts.

Splined couplings

A lock arrangement comprises a first jaw component () pivotally moveable about a pivot axis (), a second jaw component () releasably securable to the first jaw component () to form a pivotable jaw assembly (), and an actuator arrangement operable to drive the jaw assembly from a locked position to a released position.
