Abstract
(DE)
Linearführung, mit einem auf einer Führungsschiene (2) längsverschieblich angeordneten Führungswagen (1), und mit einer zur Bestimmung einer Position des Führungswagens (1) auf der Führungsschiene (2) vorgesehenen Längenmesseinrichtung (5), die zwei Messköpfe (6) sowie zwei an der Führungsschiene (2) nebeneinander angeordnete Spuren (7, 8) aufweist, die jeweils einem der Messköpfe (6) zugeordnet sind, welche Spuren (7, 8) jeweils eine Vielzahl von entlang der Spur (7, 8) hintereinander angeordneten Maßverkörperungen (9, 14) aufweist, wobei die Maßverkörperungen (9, 14) beider Spuren (7, 8) in einem Überlappungsbereich (x1, yn, z1) einander überlappen.
(EN)
The invention relates to a linear guide, comprising a guide carriage (1) arranged on a guide rail (2) so as to be longitudinally displaceable, and comprising a length measuring device (5) provided on the guide rail (2) for determining a position of the guide carriage (1), which length measuring device has two measuring heads (6) and two tracks (7, 8) arranged side-by-side on the guide rail (2), each of which tracks is assigned to one of the measuring heads (6). Each of said tracks (7, 8) has a plurality of dimensional measures (9, 14) arranged one behind the other along the track (7, 8), wherein in an overlapping region (x1, yn, z1), the dimensional measures (9, 14) of both tracks (7, 8) overlap each other.

L'invention concerne un guidage linéaire, comprenant un chariot de guidage (1) disposé de manière à pouvoir coulisser longitudinalement sur un rail de guidage (2), et comprenant un dispositif de mesure de longueur (5) conçu pour déterminer une position du chariot de guidage (1) sur le rail de guidage (2), lequel comporte deux têtes de mesure (6) ainsi que deux pistes (7, 8) disposées l'une à côté de l'autre sur le rail de guidage (2), qui sont respectivement associées à l'une des têtes de mesure (6). Lesdites pistes (7, 8) possèdent chacune une pluralité d'étalons (9, 14) disposés les uns derrière les autres le long de la piste (7, 8), les étalons (9, 14) des deux pistes (7, 8) se chevauchant mutuellement dans une zone de chevauchement (x1, yn, z1).
