Linear Actuator |
摘要 |
A linear actuator with an electric drive device includes a stator and a rotor, wherein the stator is arranged in a fixed location in a drive housing and the rotor is mounted for rotary motion relative to the stator and with a transmission arrangement which is arranged coaxial with an axis of rotation of the drive device to convert the rotary movement of the rotor into a linear movement, wherein a threaded spindle of the transmission arrangement is non-rotatably connected to the rotor and positively coupled to a spindle nut slidably accommodated in the drive housing and connected to a torque tube, which extends along the axis of rotation, and wherein a brake device is assigned to the rotor and/or to the threaded spindle. |

1. A linear actuator with an electric drive device comprising a stator and a rotor, wherein the stator is arranged in a fixed location in a drive housing and the rotor is mounted for rotary motion relative to the stator and designed for providing a rotary movement, and with a transmission arrangement which is arranged coaxial with an axis of rotation of the drive device and which is designed for converting the rotary movement of the rotor into a linear movement, wherein a threaded spindle of the transmission arrangement is non-rotatably connected to the rotor and positively coupled in the axial direction to a spindle nut slidably accommodated in the drive housing and connected to a torque tube, wherein the torque tube is mounted rotatably and slidably relative to the threaded spindle and extends along the axis of rotation, and wherein the rotor has a recess which is designed for accommodating the threaded spindle, the spindle nut and the torque tube, and wherein a brake device is assigned to the rotor and/or to the threaded spindle. |
