Description
Anordnung für Meßeinrichtungen mit einem aus Zahnstange und Zahnrad bestehenden Getriebe zur Umformung eines Hubes in eine Drehbewegung Die Erfindung betrifft eine Anordnung für Meßeinrichtungen mit einem aus Zahnstange und Zahnrad bestehenden Getriebe zur Umformung eines Hubes in eine Drehbewegung. Gemäß der Erfindung weist zur stufenlosen Veränderung des Übersetzungsverhältnisses der Zahnkörper eine in der Abwicklung fächerförmig verlaufende Zahnung auf, so daß durch Relativverstellung von Zahnrad und Zahnkörper zueinander die Änderung der Übersetzung innerhalb enger Grenzen einstellbar ist.Arrangement for measuring devices with a rack and gear wheel existing gear for converting a stroke into a rotary motion The invention relates to an arrangement for measuring devices with a rack and gear wheel existing gears for converting a stroke into a rotary movement. According to the invention has a stepless change of the gear ratio of the tooth body in the development fan-shaped teeth, so that by relative adjustment of gear and tooth body to each other the change in translation within close Limits is adjustable.
Eine derartige Anordnung kann bei zahlreichen Meßeinrichtungen Verwendung finden, die sich hinsichtlich der auszuführenden Meßvorgänge voneinander unterscheiden, jedoch stets insoweit übereinstimmen, als sie ein aus Zahnstange und Zahnrad bestehendes Umformungsgetriebe aufweisen.Such an arrangement can be used in numerous measuring devices find that differ from one another with regard to the measurement processes to be carried out, but always match insofar as they consist of a rack and gear Have conversion gear.
Die Erfindung ist an Hand der Zeichnungen an einer Differenzmeßeinrichtung mit Fluidumsübertragung als Ausführungsbeispiel erläutert. In den Zeichnungen stellt dar Fig. 1 schematisch-perspektivisch ein Ausführungsbeispiel, wobei nur das dargestellt ist, was zum Verständnis der Erfindung notwendig ist, Fig. 2 eine stark vergrößerte Abwicklung der Zahnung des Zahnkörpers, bei der die naturgemäße Feinheit der Übersetzungsänderung bei einer solchen Meßeinrichtung außer Acht gelassen ist, Fig. 3 ein Detail zu Fig. 1 und Fig.4 ein zweites Ausführungsbeispiel in schematisch-perspektivischer Form.The invention is based on the drawings on a differential measuring device explained with fluid transfer as an exemplary embodiment. In the drawings represents FIG. 1 shows a schematic perspective view of an exemplary embodiment, only that being shown is what is necessary for understanding the invention, Fig. 2 is a greatly enlarged Processing of the toothing of the tooth body, in which the natural fineness of the translation change is disregarded in such a measuring device, Fig. 3 shows a detail of Fig. 1 and 4 a second exemplary embodiment in a schematic perspective form.
In der vorliegenden Anordnung mit Fluidumsübertragung sind Faltenrohre 1 vorhanden, die unter denn Einfluß von ihrer Ausdehnung entgegenwirkenden Federn 2 stehen und je ein Schubglied 3 steuern. Der über der Skala 25 spielende Zeiger 24 der Meßeinrichtung sitzt auf der Planetenradachse 23 eines Sonnenräder 20, 21 aufweisenden Differentialgetriebes.In the present fluid transfer arrangement, there are corrugated tubes 1 present, the springs counteracting under the influence of their expansion 2 stand and each control a thrust link 3. The pointer playing above the scale 25 24 of the measuring device is seated on the planetary gear axle 23 of a sun gear 20, 21 having differential gear.
Im Zuge der Bewegungsübertragung der Schubglieder 3 auf das zugehörige Sonnenrad 20. 21 ist koaxial an dem Schubglied die Welle 27 eines zylindrischen Körpers 28 angebracht, dessen Mantelfläche eine etwa über seinen halben Umfang reichende Zah nung 29 enthält. In der Abwicklung des Körpers 28 verläuft die Zahnung 29, wie aus Fig. 2 ersichtlich ist, fächerförmig. Das darin eingreifende Zahnrad 30 sitzt auf einer Welle 31, die durch ein Zahnrad 32 mit dem Sonnenrad 20, 21 im Eingriff steht. Rückzugfedern 17 gewährleisten das dauernde Anliegen der Welle 27 am Schubglied 3 und beseitigen jedes Spiel im Bewegungsübertragungsweg.In the course of the transfer of movement of the thrust members 3 to the associated Sun gear 20. 21 is coaxial on the thrust member, the shaft 27 of a cylindrical Body 28 attached, the lateral surface of which extends approximately over half its circumference Contains tooth 29. In the development of the body 28, the toothing 29 runs, as can be seen from Fig. 2, fan-shaped. The gear 30 engaging therein is seated on a shaft 31 which meshes with the sun gear 20, 21 through a gear 32 stands. Retraction springs 17 ensure that the shaft 27 is in permanent contact with the thrust member 3 and eliminate any play in the motion transmission path.
Die Welle 27 des Zahnkörpers 28 ist in einem ortsfesten Bügel 33 drehbar und verschiebbar gelagert. Eine auf der Welle 27 befestigte Lasche 34 ist verschiebbar an einem in eine Scheibe 36 eingesetzten Durch die Winkelverdrehung des Zahnkörpers 28 kann also eine lineare und stufenlose, dabei in der Übersetzungsänderung zwangläufge ausgleichende Einstellung erfolgen.The shaft 27 of the tooth body 28 is rotatably and displaceably mounted in a stationary bracket 33. A bracket 34 fastened on the shaft 27 is displaceable on an inserted into a disk 36. The angular rotation of the toothed body 28 thus enables a linear and stepless adjustment which inevitably compensates for the change in transmission ratio.
Der Zahnkörper könnte auch statt aus einem zylindrischen aus einem Plänstück 39 (Fig. 4) gebildet sein, das die dann plane Zahnung 29 aufweist. Das Planstück 39 ist im Bügel 33 unverdrehbar geführt, und zum Eingriff des Rades 30 in eine beliebige Zone der Zahnung 29 ist die Welle 31 mittels eines Exzenters 40 heb- und senkbar. Die Auflage der Welle 31 auf dem Exzenter 40 kann durch Federzug gesichert sein.The tooth body could also instead of a cylindrical from a Plan piece 39 (FIG. 4) can be formed, which then has the planar teeth 29. That The face piece 39 is guided non-rotatably in the bracket 33, and for the engagement of the wheel 30 The shaft 31 is in any zone of the teeth 29 by means of an eccentric 40 can be raised and lowered. The support of the shaft 31 on the eccentric 40 can be done by means of a spring tensioner be secured.
Die neue Anordnung hat die Vorteile großer Einfachheit und weitgehender Zwangläufigkeit in der Übertragung.The new arrangement has the advantages of great simplicity and extensive Inevitability in the transfer.
