Abstract
Linearführung, mit an einem Gehäuse (2) parallel zueinander angeordneten Führungsschienen (1) und mit einem Schlitten (3), der an den Führungsschienen (1) mittels Linearwälzlager (4) linearbeweglich gelagert ist, und mit einem zwischen den Führungsschienen (1) angeordneten Linearmotor (5), der ein Primärteil (6) und ein Sekundärteil (7) aufweist, wobei das Primärteil (6) mit zwei an gegenüberliegenden Seiten des Primärteiles (6) angeordneten Sekundärteilen (7) zusammenwirkt.Linear guide, with guide rails (1) arranged parallel to each other on a housing (2) and with a slide (3) which is mounted on the guide rails (1) by means of linear roller bearings (4) and with one arranged between the guide rails (1) Linear motor (5) which has a primary part (6) and a secondary part (7), the primary part (6) cooperating with two secondary parts (7) arranged on opposite sides of the primary part (6).
Description
Die vorliegende Erfindung betrifft eine Linearführung, die mit einem Linearmotor versehen ist. Derartige Linearführungen, die auch als Linearantriebseinheiten oder Lineartische bezeichnet werden können, finden zunehmend Anwendung beispielsweise im Werkzeugmaschinenbau und in der Handhabungstechnik.The The present invention relates to a linear guide using a linear motor is provided. Such linear guides, which are also referred to as linear drive units or linear tables can be are increasingly used, for example, in machine tool construction and in handling technology.
Aus
Aufgabe der vorliegenden Erfindung ist es, eine Linearführung nach den Merkmalen des Oberbegriffs Anspruchs 1 anzugeben, bei der dieser Nachteil behoben ist. Erfindungsgemäß wird diese Aufgabe dadurch gelöst, das das Primärteil mit zwei an gegenüberliegenden Seiten des Primärteiles angeordneten Sekundärteilen zusammenwirkt. Durch diese symmetrische Anordnung der Sekundärteile zu bei den Seiten des Primärteiles heben sich die Querkraftkomponenten weitgehend auf. Eine besondere Dimensionierung die Linearwälzlager mit Rücksicht auf diese Querkraftkomponente kann daher entfallen.task the present invention is a linear guide according to the features of Specify the preamble of claim 1, in which this disadvantage is eliminated is. According to the invention, this task solved by that's the primary part with two on opposite Sides of the primary part arranged secondary parts interacts. Due to this symmetrical arrangement of the secondary parts Sides of the primary part the lateral force components largely cancel each other out. A special dimensioning the linear roller bearings with regard to this shear force component can therefore be omitted.
Eine erfindungsgemäße Weiterbildung sieht vor, daß die zwischen dem Primärteil und dem jeweiligen Sekundärteil wirksame Kraft in einer Ebene wirksam ist, die parallel zu einer Ebene angeordnet ist, in der die Führungsschiene liegen. In diesem Fall sind vorzugsweise die beiden quer zur Bewegungsrichtung wirksamen Querkraftkomponenten entgegengerichtet und gleich groß.A Training according to the invention stipulates that the between the primary part and the respective secondary part effective force is effective in a plane that is parallel to one Level is arranged in which the guide rail lie. In this Case are preferably the two effective across the direction of movement Shear force components opposed and of the same size.
Vorzugsweise ist das Primärteil dem Schlitten zugeordnet, wobei zwischen der einen Führungsschiene und dem Primärteil das eine Sekundärteil und zwischen der anderen Führungsschiene und dem Primärteil das andere Sekundärteil angeordnet ist, wobei beide Sekundärteile dem Gehäuse zugeordnet sind.Preferably is the primary part assigned to the slide, between the one guide rail and the primary part the one secondary part and between the other guide rail and the primary part the other secondary part is arranged, with both secondary parts assigned to the housing are.
Das Sekundärteil ist vorzugsweise durch eine Vielzahl hintereinander und parallel zu den Führungsschienen angeordneter Permanentmagnete gebildet.The secondary part is preferably by a large number in a row and in parallel to the guide rails arranged permanent magnets formed.
Nachstehend wird die Erfindung anhand eines in zwei Figuren dargestellten Ausführungsbeispieles näher erläutert. Es zeigen:below The invention is based on an embodiment shown in two figures explained in more detail. It demonstrate:
