ELECTRIC ACTUATORS HAVING INTERNAL LOAD APPARATUS. |
摘要 |
<p>Electric actuators ( 102 ) having internal load apparatus are described herein. An example electric actuator having an internal load apparatus described herein includes a housing ( 136, 138 ) defining a cavity to receive a drive system ( 144 ) and a drive shaft ( 148 ) operatively coupled to the drive system. Rotation of the drive system in a first rotational direction causes the drive shaft to move in a first rectilinear direction and rotation of the drive system in a second rotational direction causes the drive shaft to move in a second rectilinear direction opposite the first rectilinear direction. A biasing element ( 186 ) is operatively coupled to the drive system ( 144 ) such that least a portion of the drive system moves axially toward the biasing element to deflect the biasing element when the drive shaft ( 148 ) reaches an end of stroke position to provide a load to the drive shaft when electric power to the electric actuator ( 102 ) is removed.</p> |
