Abstract
The invention concerns a displacement device comprising a transmission 2 driven by an electric motor 1, guide rails 5, a displacement slider 6, a transmission housing 8 and a closure cover 7, characterized in that an externally threaded nut (4) is arranged longitudinally slidably on a profile bar (3) between the transmission (2) and said externally threaded nut (4) and said externally threaded nut (4) is mounted rotatably in a displacement slider (6) in such a way that said externally threaded nut (4) is longitudinally displaced upon rotation by the transmission (2) which is driven by the drive motor (1) and the profile bar (3) in the thread profile segments of the guide rails (5) and is displaced along the guide rails (5) by way of the end run-on surfaces (9) of the displacement slider (6).
Claims5
A displacement drive comprising a transmission driven by an electric motor, guide rails having thread profile segments, a displacement slider, a transmission housing and a closure cover, wherein an externally threaded nut is arranged longitudinally slidably on a profile bar connected to the transmission and said externally threaded nut engages into said thread profile segments of said guide rail and is mounted rotatably in said displacement slider in such a way that said externally threaded nut is longitudinally displaced upon rotation by the transmission which is driven by said electric motor and the profile bar wherein said externally threaded nut rotates while engaged in the thread profile segments of the guide rails and said externally threaded nut is displaced along the guide rails wherein the nut drives the displacement slider via the end run-on surfaces on said displacement slider.
