Abstract

The guide has two pairs of flat spring elements (1), whereby the fixed ends of the elements are arranged opposite each other and their free ends are joined by link rods (2) with central flexible cross spring joints (3) as bearings for the linearly movable guide element (4).

Description

Die Erfindung betrifft ein reibungsfreies mechanisches Linearführungssystem.The invention relates to a frictionless mechanical linear guide system.

Hochgenaue Positioniersysteme benötigen reibungsarme, nahezu spielfreie und wartungsfreie Linearführungen bei geringen Winkelfehlern und Parallelitätsfehlern.High-precision positioning systems require low-friction, almost backlash-free and maintenance-free linear guides with low angular errors and parallelism errors.

Der dem Erfindungsgegenstand nächstkommende Stand der Technik ist beschrieben in: HOFFROGGE, Chr.; RADEMACHER, H.-J.: Eine Doppelparallelfeder als Präzisi­ onsführung. - In: PTB-Mitteilungen 2/73, S. 79-82. Bei dieser bekannten Vorrich­ tung werden Paare von Blattfedern verwendet.The closest prior art to the subject of the invention is described in: HOFFROGGE, Chr .; RADEMACHER, H.-J .: A double parallel spring as a precision guide. - In: PTB-Mitteilungen 2/73, pp 79-82. In this known Vorrich device pairs of leaf springs are used.

Aufgabe der Erfindung ist es, eine Präzisions-Linearführung mit folgenden Merk­ malen zu schaffen:
The object of the invention is to provide a precision linear guide with the following characteristics:

  • - reibungsfrei- smoothly
  • - spielfrei- free of play
  • - Wege (je nach Auslegung) ca. 50 mm- Paths (depending on the design) approx. 50 mm
  • - kleine Parallelitätsfehler und Winkelfehler (ca. 80 µm Parallelitätsfehler über Hub, ca. 20 arcsec Winkelfehler).- small parallelism errors and angular errors (approx. 80 µm parallelism errors over stroke, approx. 20 arcsec angle errors).

Diese Aufgabe wird erfindungsgemäss gelöst durch eine Linearführung mit zwei Paaren ebener Blattfederelemente, wobei die ortsfesten Enden der Blattfeder­ elemente sich jeweils gegenüberliegend angeordnet sind und die freien Enden jedes Blattfederpaares mittels jeweils eines Lenkers miteinander verbunden sind und wobei in der Mitte jedes Lenkers jeweils ein flexibles Kreuzfedergelenk als Lagerung für das linear bewegliche Führungselement vorhanden ist. According to the invention, this object is achieved by a linear guide with two Pairs of flat leaf spring elements, the fixed ends of the leaf spring elements are arranged opposite each other and the free ends of each Leaf spring pair are connected to each other by means of a handlebar and with a flexible cross spring joint in the middle of each handlebar as storage is available for the linearly movable guide element.  

Die Erfindung wird nachfolgend anhand einer Figur näher erläutert, die das Linear­ führungssystem in seitlicher Ansicht zeigt.The invention is explained in more detail below with reference to a figure which shows the linear guidance system shows in a side view.

Die Linearführung der einzigen Figur ist aus zwei Paaren ebener Blattfederelemente 1 aufgebaut, wobei die ortsfesten Enden der Blattfederelemente jeweils gegenüber­ liegend angeordnet sind. Jeweils ein Ende jeder Blattfeder ist an der Struktur befestigt. Die freien Enden jedes Blattfederpaares sind über jeweils einen Lenker 2 miteinander verbunden, wobei in deren Mitte je ein flexibles Kreuzfedergelenk 3 als Lagerung für das linear bewegliche Führungselement 4 angebracht ist.The linear guide of the single figure is made up of two pairs of flat leaf spring elements 1 , the fixed ends of the leaf spring elements being arranged opposite each other. One end of each leaf spring is attached to the structure. The free ends of each pair of leaf springs are connected to each other via a link 2 , a flexible cross spring joint 3 being mounted in the middle of each as a bearing for the linearly movable guide element 4 .

Bei Bewegung des linear beweglichen Führungselements 4 in axialer Richtung werden die Blattfederelemente so ausgelenkt, dass sich sowohl Lateralfehler als auch Winkelfehler weitgehend kompensieren und somit eine präzise Längsführung möglich ist. Laterale Kräfte werden mittels der Blattfederelemente aufgenommen. Das Führungselement 4 kann lediglich axial bewegt werden.When the linearly movable guide element 4 is moved in the axial direction, the leaf spring elements are deflected in such a way that both lateral errors and angular errors largely compensate for one another and thus a precise longitudinal guidance is possible. Lateral forces are absorbed by the leaf spring elements. The guide element 4 can only be moved axially.
