Abstract

A double gear train (4,5), driven by an electric motor (11), is secured via a housing (10) to the middle profile tube (8). One worm gear (4) forms inside a threaded nut. The threaded spindle (1), non-rotary couple to outer profile tube (7), provides displacement work between the outer and middle profile tubes on the motor rotation. A second spindle (2), non-rotary fitted in second work gear (5), provides displacement work, via spindle nut (6) firmly coupled to inner profile tube (9), between outer and inner tube, on motor rotation. Drive is taken of worm gear shaft (12).

1. Verstellvorrichtung bestehend aus drei ineinander mittels Kugelführungen gelagerten Profilrohren 7/8/9 dadurch gekennzeichnet, dass ein durch einen elektrischen Motor 11 angetriebener doppelter Zahnradsatz 4/5 mittels umschliessendem Gehäuse 10 am mittleren Profilrohr 8 befestigt ist und das eine Schneckenrad 4 innen als Gewindemutter ausgebildet ist und die am äusseren Profilrohr 7 drehfest verbundene Gewindespindel 1 bei Drehung des Motors 11 zwischen dem äusseren 7 und mittleren Profilrohr 8 Verstellarbeit leistet sowie einer im zweiten Schneckenrad 5 drehfest angeordneten Spindel 2 über die fest mit dem inneren Profilrohr 9 verbundenen Spindelmutter 6 bei der gleichen Drehung Verstellarbeit zwischen dem mittleren 8 und dem inneren Profilrohr 9 leistet und sich dadurch das äussere 7 und innere Profilrohr 9 bei Drehung des Motors und Antrieb über die Schneckenwelle 12 auf die beiden Schneckenräder 4/5 und den darin angeordneten Spindeln 1/2 entgegengesetzt vom mittleren Profilrohr verstellt werden.1. Adjusting device consisting of three profiled tubes 7/8/9 mounted one inside the other by means of ball guides, characterized in that a double gear set 4/5 driven by an electric motor 11 is fastened to the central profiled tube 8 by means of an enclosing housing 10 and the one worm wheel 4 inside as a threaded nut is formed and the threaded spindle 1, which is connected in a rotationally fixed manner to the outer profile tube 7 when the motor 11 rotates, performs adjustment work between the outer 7 and the middle profile tube 8, and a spindle 2, which is arranged in the second worm wheel 5 in a rotationally fixed manner, via the spindle nut 6 which is fixedly connected to the inner profile tube 9 same rotation adjustment work between the middle 8 and the inner profile tube 9 and thereby the outer 7 and inner profile tube 9 when rotating the motor and drive via the worm shaft 12 on the two worm wheels 4/5 and the spindles arranged therein 1/2 opposite middle P profile tube can be adjusted. 2. Verstellvorrichtung nach Anspruch 1 dadurch gekennzeichnet, dass an der Schneckenwelle 12 des Elektromotors 11 vier oder mehr Schneckenräder angeordnet sind und die Schneckenräder 4/5/13/14 mit in den Schneckenräder 4/13 befindlichen Muttern und den Schneckenrädern 5/14 in die Spindeln 1/2/15/16 das sie über Kreuz angeordnet sind, so dass das Kippmoment aus dem Abstand der Spindeln sich aufheben.2. Adjusting device according to claim 1, characterized in that on the Worm shaft 12 of the electric motor 11 four or more worm wheels are arranged and the worm wheels 4/5/13/14 with those in the worm wheels 4/13 Nuts and the worm wheels 5/14 in the spindles 1/2/15/16 that they cross are arranged so that the tilting moment cancel each other out of the distance between the spindles. 3. Verstellantriebe nach Ansprüchen 1 und 2 dadurch gekennzeichnet, dass die Gewindespindel 1/2 unterschiedliche Steigungen aufweisen, so dass das inneren Profilrohres 9 zum mittleren 8 einen anderen Weg als das äussere 7 zum mittleren 8 zurücklegt.3. actuators according to claims 1 and 2, characterized in that the Threaded spindle 1/2 have different pitches, so that the inner Profile tube 9 to the middle 8 a different way than the outer 7 to the middle 8 travels.
