Description
Die vorliegende Erfindung betrifft eine Führungsschiene für ein Linearlager. Führungswagen werden auf diesen Führungsschienen über Wälzkörper wälzgelagert und entlang der Führungsschiene geführt.The present invention relates to a guide rail for a linear bearing. Guide carriages are roller-mounted on these guide rails via rolling elements and guided along the guide rail.

Aufgabe der vorliegenden Erfindung ist es, eine Führungsschiene nach den Merkmalen des Oberbegriffs des Anspruchs 1 anzugeben, die eine einfache und zuverlässige Montage eines Abdeckbandes ermöglicht.Object of the present invention is to provide a guide rail according to the features of the preamble of claim 1, which allows a simple and reliable installation of a cover strip.
Erfindungsgemäß wird diese Aufgabe durch die Führungsschiene gemäß Anspruch 1 gelöst. Dadurch, dass das Deckband über Magnetkraft an der Führungsschiene gehalten ist müssen keine Eindrückkräfte aufgebracht werden. Das Deckband kann an die Führungsschiene angebracht und von dieser entfernt werden, ohne dass ein unerwünschter Verschleiß auftreten kann. Für die Erfindung kann ein Magnet vorgesehen sein, der in seiner Umgebung ein Magnetfeld erzeugt und ferner ein Körper, der im Magnetfeld eine Kraftwirkung erfährt.According to the invention this object is achieved by the guide rail according to claim 1. The fact that the shroud is held by magnetic force on the guide rail no indentation forces must be applied. The shroud can be attached to and removed from the guide rail without undesirable wear. For the invention, a magnet may be provided which generates a magnetic field in its environment and also a body which undergoes a force effect in the magnetic field.
Erfindungsgemäß weist das Deckband Magnetstoff auf, wobei die Führungsschiene magnetisierbar ist, also im Magnetfeld des Deckbandes eine Kraftwirkung erfährt. Derartige Deckbänder können flexibel ausgebildet sein. Erfindungsgemäß weist das Deckband eine Decklage auf und eine untere der Führungsschiene zugewandte Lage mit Magnetstoff. Diese untere Lage kann dann auf der magnetisierbaren Führungsschiene aufliegen und dabei die Durchgangsöffnungen bedecken. Die Decklage kann als Stahlband ausgebildet sein. Das Stahlband schützt die empfindliche untere Lage vor Verunreinigungen und vor direktem Kontakt mit Fremdkörpern. Die untere Lage kann beispielsweise aus Kunststoff mit beigemischtem Magnetstoff gebildet sein. Derartige Kunststoffbänder lassen sich in wirtschaftlicher Weise beispielsweise im Spritzverfahren herstellen.According to the invention, the shroud comprises magnetic material, wherein the guide rail is magnetizable, that is, experiences a force effect in the magnetic field of the shroud. Such shrouds can be designed to be flexible. According to the invention, the shroud has a cover layer and a lower guide rail facing the layer with magnetic material. This lower layer can then rest on the magnetizable guide rail and thereby cover the passage openings. The cover layer may be formed as a steel band. The steel strip protects the sensitive bottom layer from contamination and from direct contact with foreign bodies. The lower layer can be formed for example of plastic mixed with magnetic material. Such plastic bands can be produced in an economical manner, for example by injection molding.
Vorzugsweise weist die Führungsschiene eine zur Schienenoberseite offene Längsnut auf, die sich über die gesamte Länge der Führungsschiene erstrecken kann. Die Durchgangsöffnungen münden in diese Längsnut ein, wobei das Deckband in die Längsnut eingreift. Erfindungsgemäß ist das Deckband mehrlagig ausgebildet. Hierbei bietet es sich an wenn die Decklage Schultern der Führungsschiene überlappt, wobei die untere magnetische Lage in der Längsnut angeordnet ist. Die untere magnetische Lage ist somit in Umfangsrichtung vollständig geschützt.Preferably, the guide rail has an open longitudinal groove to the top of the rail, which can extend over the entire length of the guide rail. The passage openings open into this longitudinal groove, wherein the shroud engages in the longitudinal groove. According to the invention, the shroud is multi-layered. In this case, it makes sense if the top layer overlaps shoulders of the guide rail, wherein the lower magnetic layer is arranged in the longitudinal groove. The lower magnetic layer is thus completely protected in the circumferential direction.
Es ist bekannt, dass bei Linearwälzlagern Längenmesssysteme zum Einsatz kommen, bei dem die Position des Führungswagens auf der Führungsschiene bestimmt und jede gewünschte Position längs der Führungsschiene angesteuert werden kann. Oftmals werden hierzu als Maßverkörperung auf der Führungsschiene Magnetbänder eingesetzt. Das erfindungsgemäße Deckband kann codiert werden, indem Magnetstoff daran verteilt wird. Dieses codierte Deckband bildet dann zugleich eine Maßverkörperung.It is known that in linear bearings length measuring systems are used, in which the position of the guide carriage on the guide rail determined and any desired position along the guide rail can be controlled. Often, magnetic tapes are used for this purpose as a material measure on the guide rail. The shroud according to the invention can be coded by distributing magnetic material thereon. This coded shroud then also forms a material measure.
Nachstehend wird die Erfindung anhand von drei in sechs Figuren dargestellten Ausführungsbeispielen näher erläutert. Es zeigen:The invention will be explained in more detail with reference to three embodiments shown in six figures. Show it:
