Description
Wälzkörperkäfig für Längsführungen mit winklig zueinander stehenden.Wälzkörperlaufbahnen Für die Lagerung von hin und her bewegten Schlitten im Maschinen- und Apparatebau wird in zunehinendem Maße die gleitende Reibung durch die Verwendung zylindrischer Wälzkörper vermindert. Die Wälzkörper sind dabei in flachen Käfigen gehalten und geführt. Käfige für die Führung der Rollen auf geraden Wälzkörperlaufbahnen sind seit längerer Zeit bekannt und bieten keine Schwierigkeiten mehr. Dies ist jedoch bei Führungsbahnen, die unter einem bestimmten Winkel zueinander stehen, nicht der Fall. Es müssen entweder besondere Wälzkörperlaufbahnen vorgesehen werden, oder man ist gezwungen, einen Winkelflachkäfig mit konstantem Winkel einzubauen. Führungsbahnen, die unter einem Winkel zueinander stehen, kommen für die verschiedensten Anwendungsgebiete in Frage, wobei der Winkel zwischen den Führungsbahnen bei den verschiedenen Längsführungen in weiten Grenzen geändert wird. Das macht es erforderlich, daß für jeden Winkel ein besonderer Käfig hergestellt werden muß, was zu einer Vielzahl von Ausführungen mit der damit bedingten entsprechend großen Lagerhaltung führt.Rolling element cage for longitudinal guides with angled rolling element raceways For the storage of back and forth moving carriages in machine and apparatus construction the sliding friction becomes to an increasing extent through the use of cylindrical Rolling elements reduced. The rolling elements are held in flat cages and guided. Cages for guiding the rollers on straight rolling element raceways are known for a long time and no longer offer any difficulties. However, this is for guideways that are at a certain angle to each other, not the Case. Either special rolling element raceways must be provided, or one is forced to install an angled flat cage with a constant angle. Guideways, which are at an angle to each other, come for a wide variety of applications in question, the angle between the guideways in the various longitudinal guides is changed within wide limits. That makes it necessary for every angle a special cage must be made, resulting in a variety of designs with the resulting correspondingly large storage leads.
Es sind winkelig geformte Kugelkäfige für umlaufende Lagerungen zur Aufnahme von radialen und axialen Belastungen bekannt, bei denen ein Schenkel aus einem konischen Ring besteht und damit den dazugehörigen Laufbahnen angepaßt ist, während der andere Schenkel aus radial gerichteten einzelnen Lappen gebildet wird, die mit dem konischen Teil scharnierartig verbunden sind. Die Winkelbeweglichkeit der Lappen gegenüber dem konischen Ring ist durch das Spiel der Kugeln an den Taschen begrenzt und erforderlich, um die Lagerung ein- bzw. nachzustellen. Größere Winkelveränderungen führen zur Bildung eines Vielecks und verhindern damit eine umlaufende Bewegung. I Weiter sind Käfige für Längsführungen mit Wälzkörperlaufbahnen, die unter einem Winkel zueinander stehen, bekanntgeworden, bei denen die Käfigplatten jedoch unter einem festen Winkel zueinander stehen. Diesen Käfigen haftet aber der Nachteil an, daß sie nur für Wälzkörperlaufbahnen verwendet werden können, die unter dem gleichen Winkel zueinander stehen. Es ist nicht möglich, bei solchen Käfigen den Winkel zwischen den Käfigplatten nachträglich zu ändern.There are angularly shaped ball cages for circumferential bearings Acceptance of radial and axial loads known in which one leg is made consists of a conical ring and is therefore adapted to the associated raceways, while the other leg is formed from radially directed individual lobes, which are connected to the conical part in a hinge-like manner. The angular mobility the lobe opposite the conical ring is due to the play of the balls on the pockets limited and required to adjust or adjust the storage. Larger angle changes lead to the formation of a polygon and thus prevent circumferential movement. I Next are cages for longitudinal guides with rolling element raceways that are under a Angle to each other, became known, in which the cage plates, however, under stand at a fixed angle to each other. However, these cages have the disadvantage that they can only be used for rolling element raceways that are under the same At an angle to each other. It is not possible to change the angle between these cages to change the cage plates later.
Aufgabe der Erfindung ist es nun, einen Käfig für Längsführungen mit winklig zueinander stehenden Wälzkörperlaufbahnen zu schaffen, der nahezu zwanglos Führungen mit verschieden großem Winkel zwischen den Wälzkörperlaufbahnen anpaßbar ist. Erfindungsgemäß geschieht dies dadurch, daß der Wälzkörperkäfig, der aus zwei miteinander verbundenen verhältnismäßig biegesteifen Käfigplatten mit je einer Reihe von auf den Wälzkörperlaufbahnen sich abwälzenden Rollen besteht, so ausgebildet ist, daß die Käfigplatten gegeneinander schwenkbar miteinander verbunden sind.The object of the invention is now to create a cage for longitudinal guides with rolling element raceways at an angle to one another, which can be adapted almost freely to guides with different angles between the rolling element raceways. According to the invention, this is done in that the rolling element cage, which consists of two relatively rigid cage plates connected to one another, each with a row of rollers rolling on the rolling element raceways, is designed so that the cage plates are mutually pivotably connected to one another.
Die Erfindung schlägt vor, die Käfigplatten beispielsweise durch ein Scharnier miteinander zu verbinden.The invention proposes the cage plates for example by a Connect hinge together.
Es ist aber auch möglich, den Wälzkörperkäfig einstückig aus Kunststoff herzustellen und die gegenseitige Beweglichkeit der Käfigplatten durch eine plastische oder federnde Verformung des zwischen ihnen befindlichen geschwächten Werkstoffes herbeizuführen.But it is also possible to make the roller body cage in one piece from plastic produce and the mutual mobility of the cage plates by a plastic or resilient deformation of the weakened material located between them bring about.
