Abstract
An actuator includes a housing assembly, an actuator shaft, an actuation member, and an anti-rotation rod. The actuator shaft is rotationally mounted in the housing assembly, is adapted to receive a drive torque, and is configured, upon receipt of the drive torque, to rotate. The actuation member is mounted on the actuator shaft, and is configured to translate in response to rotation of the actuator shaft. The anti-rotation rod is coupled to the actuator housing and extends therefrom. The anti-rotation is rod configured to at least selectively engage, and thereby prevent rotation of, the actuation member.
Claims20
An actuator, comprising:
- a housing assembly;
- an actuator shaft rotationally mounted in the housing assembly, the actuator shaft adapted to receive a drive torque and configured, upon receipt thereof, to rotate;
- an actuation member mounted on the actuator shaft, the actuation member configured to translate in response to rotation of the actuator shaft;
- and
- an anti-rotation rod coupled to the actuator housing and extending therefrom, the anti-rotation rod configured to at least selectively engage, and thereby prevent rotation of, the actuation member.
An actuator, comprising:
- a housing assembly;
- an actuator shaft rotationally mounted in the housing assembly, the actuator shaft adapted to receive a drive torque and configured, upon receipt thereof, to rotate;
- an actuation member mounted on the actuator shaft, the actuation member configured to translate in response to rotation of the actuator shaft;
- a rod engagement structure extending from the actuation member and translatable therewith, the rod engagement structure including a first arm and a second arm, the first arm and the second arm spaced apart from each other to define a rod passageway;
- and
- an anti-rotation rod coupled to the actuator housing and extending therefrom through the rod passageway, the anti-rotation rod configured to at least selectively engage the rod engagement structure, to thereby prevent rotation of the actuation member.
An actuator, comprising:
- a housing assembly;
- a ball screw rotationally mounted in the housing assembly, the ball screw adapted to receive a drive torque and configured, upon receipt thereof, to rotate;
- a ball nut mounted on the actuator shaft, the ball nut configured to translate in response to rotation of the actuator shaft;
- a rod engagement structure extending from the ball nut and translatable therewith;
- and
- an anti-rotation rod coupled to the actuator housing and extending therefrom, the anti-rotation rod configured to at least selectively engage the rod engagement structure, and thereby prevent rotation of the ball nut.
