Abstract
Die Erfindung betrifft eine Linearschiene mit einer Schmierstruktur, die umfasst: eine Schiene (10), die Laufrillen (11) aufweist; einen Schieber (2), der um die Schiene (1) gelegt ist und entsprechend den Laufrillen (11) Laufnuten (21), die mit den Laufnuten (21) Laufkanäle (90) bilden, und Rückführbohrungen (22) aufweist; zwei Deckel (3), die an den beiden Seiten in der Achsrichtung (X) des Schiebers (2) angeordnet sind und Rücklaufkanäle aufweisen, die eine U-Form haben und an den beiden Enden mit den Laufkanälen (90) und den Rückführbohrungen (22) verbunden sind, wobei zwei Rückführkanäle, ein Laufkanal (90) und eine Rückführbohrung (22) einen Kreislaufkanal bilden; und eine Vielzahl von Rollkörpern (7), die in den Kreislaufkanälen angeordnet sind, wobei im Deckel (3) ein Ölkanal (33) vorgesehen ist, der mit einer externen Ölquelle verbunden ist, wobei sich die andere Öffnung (331) des Ölkanals (33) nahe an dem Laufkanal (90) befindet und in der Achsrichtung (X) erstreckt.The invention relates to a linear rail with a lubricating structure comprising: a rail (10) having running grooves (11); a slide (2) which is placed around the rail (1) and has, corresponding to the running grooves (11) running grooves (21) which form running channels (90) with the running grooves (21), and return bores (22); two covers (3), which are arranged on the two sides in the axial direction (X) of the slide (2) and have return channels that have a U-shape and at the two ends with the run channels (90) and the return bores (22 ) are connected, two return channels, a run channel (90) and a return bore (22) forming a circulation channel; and a plurality of rolling bodies (7) which are arranged in the circulation channels, wherein an oil channel (33) is provided in the cover (3), which is connected to an external oil source, the other opening (331) of the oil channel (33 ) is located close to the runner channel (90) and extends in the axial direction (X).
Description
Die Erfindung betrifft eine Linearschiene, insbesondere eine Linearschiene mit einer Schmierstruktur.The invention relates to a linear rail, in particular a linear rail with a lubricating structure.
Die herkömmliche Schmierstruktur einer Linearschiene, wie aus dem taiwanesischen Patent
Wenn die Rollkörper durch den Rückführkanal fließen, werden sie geschmiert, wodurch die Rollkörper reibungslos zwischen dem Schieber und der Schiene rollen können, so dass die Lebensdauer der Linearschiene verlängert wird.As the rollers flow through the return passage, they are lubricated, allowing the rollers to smoothly roll between the slider and the rail, thus extending the life of the linear rail.
Diese Linearschiene ist jedoch nicht für eine Anlage mit einer kurzen Bewegungsstrecke geeignet, bei der eine kleine Hin- und Herbewegung durchgeführt wird. D. h. der Schieber wird um eine kleine Strecke gegenüber der Schiene hin und her bewegt. Die Bewegungsstrecke ist von der Abmessung der Linearschiene abhängig und liegt üblicherweise im Bereich von 5 mm bis 20 mm. Dadurch können die Rollkörper zwischen dem Schieber und der Schiene nicht in den Rückführkanal rollen und werden somit nicht geschmiert, so dass die Rollkörper mit dem Schieber und der Schiene eine Reibung erzeugen. Daher wird ein Geräusch erzeugt und die Bewegung beeinträchtigt.However, this linear rail is not suitable for a system with a short moving distance, in which a small reciprocating motion is performed. Ie. the slider is moved back and forth a short distance from the rail. The travel distance is dependent on the dimension of the linear rail and is usually in the range of 5 mm to 20 mm. As a result, the rolling elements between the slider and the rail can not roll in the return channel and are thus not lubricated, so that the rolling elements generate friction with the slider and the rail. Therefore, a noise is generated and the movement is impaired.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Linearschiene mit einer Schmierstruktur zu schaffen, die eine gleichmäßige Schmierung erreichen kann und für unterschiedliche Linearschienen geeignet ist.The invention has for its object to provide a linear rail with a lubricating structure, which can achieve a uniform lubrication and is suitable for different linear rails.
Erfindungsgemäß wird eine Linearschine gemäß Anspruch 1 vorgeschlagen. Einge beispielhafte Weiterbildungen einer solchen Laufschiene sind in den Unteransprüchen genannt.According to the invention, a linear machine according to
Vorzugsweise weist der Schieber einen Halter auf, der eine Führungsfläche besitzt, die von der Planfläche einen Abstand hat, der eine Schmierölführung definiert, wobei die Schmierölführung mit der Öffnung des Ölkanals verbunden ist.Preferably, the slider has a holder having a guide surface spaced from the face surface defining a lubricating oil guide, the lubricating oil guide being connected to the opening of the oil passage.
Vorzugsweise weist der Schieber einen Halter auf, der eine Führungsfläche besitzt, die an der Planfläche anliegt, wobei die Führungsfläche des Halters eine Längsnut in der Achsrichtung, die mit der Öffnung verbunden ist, und eine Vielzahl von Quernuten besitzt, die mit der Längsnut verbunden sind, wobei die Längsnut und die Quernuten mit der Planfläche eine Schmierölführung bilden.Preferably, the slider has a holder having a guide surface abutting the planar surface, the guide surface of the holder having a longitudinal groove in the axial direction which is connected to the opening, and a plurality of transverse grooves which are connected to the longitudinal groove wherein the longitudinal groove and the transverse grooves with the flat surface form a lubricating oil guide.
Dadurch, dass der Schieber einen Halter aufweist, der eine Führungsfläche besitzt, die von der Planfläche einen Abstand hat, der nicht gleichbleibend ist und eine Schmierölführung definiert, die mit der Öffnung des Ölkanals verbunden ist kann das Schmieröl direkt die Rollkörper in den Laufkanälen schmieren.Characterized in that the slide has a holder which has a guide surface which has a distance from the flat surface, which is not consistent and defines a lubricating oil guide, which is connected to the opening of the oil passage, the lubricating oil directly lubricate the rolling bodies in the flow channels.
