Description
Ein großer Teil der Geräusche von kleinen Maschinen, z. B. Haushaltungsmaschinen, wie Staubsauger u. dgl., wird durch die bei diesen Maschinen vielfach zur Anwendung kommenden Rollkörperlager, insbesondere von den Kugellagern, verursacht, die dadurch entstehen, daß die Kugeln einerseits zwischen der von ihnen geführten Welle und anderseits von dem Laufring, von dem sie geführt ίο werden, ein gewisses Spiel haben, dessen Größe durch Ungleichmäßigkeiten in der Fabrikation und Ausdehnung durch die im Betrieb auftretende Erwärmung und ähnliche Gründe bedingt ist. Außerdem müssen die Kugeln auch stets ein gewisses Spiel innerhalb des Käfigs haben. Beim Laufen, springen die Kugeln leicht hin und her, wobei sie entweder etwas stärker an die Welle oder an den Laufring oder auch an den Käfig anschlagen und hierdurch das störende Geräusch verursachen.Much of the noise from small machines, e.g. B. Household machines, such as Vacuum cleaners and the like are widely used by these machines Rolling body bearings, in particular from the ball bearings, which arise as a result, that the balls on the one hand between the shaft guided by them and on the other hand by the race from which they are guided ίο will have a certain amount of play, the size of which is due to irregularities in the fabrication and expansion due to the heating occurring during operation and the like Reasons is conditional. In addition, the balls must always have a certain amount of play within of the cage. When running, the balls bounce slightly back and forth, taking them either hit the shaft a little harder, the race ring or the cage and thereby cause the disturbing noise.
Es ist versucht, diese durch die Rollkörperlager hervorgerufenen Geräusche durch Federung zu dämpfen. Beim Erfindungsgegenstand wird dies dadurch erreicht, daß die Kugeln durch Verwendung federnder, genügend gedämpfter Elemente an dem Ausschlagen und der Hinundherbewegung verhindert werden, wobei zweckmäßig jede Kugel für sich auf einer parallel zu der Welle verlaufenden, in radialer Richtung federnden Achse sitzt, an deren Enden sich ebenfalls Kugeln befinden. Eine Reihe derartiger Achsen sind um die Welle herum angeordnet, so daß sie annähernd einen Zylindermantel bilden.An attempt is made to reduce these noises caused by the rolling element bearings by means of suspension to dampen. In the subject matter of the invention, this is achieved in that the balls by using resilient, sufficient damped elements are prevented from deflecting and reciprocating, each ball being expedient for itself on a parallel to the shaft, resilient in the radial direction Axis sits, at the ends of which there are also balls. A number of those Axes are arranged around the shaft, so that they are approximately a cylinder jacket form.
In der Abbildung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. Die Welle 11 ist mit einem Laufring 12 für die Kugeln 13 versehen, deren jede auf einer federnden Achse 14 angeordnet ist. Die Enden der federnden Achsen 14 sind mit je einer Kugel 15 versehen, die in mit dem Maschinengehäuse befestigten Lauf ringen 16 gelagert sind. Die federnden Achsen 14 umgeben die Welle 11 nach Art eines Zylindermantels. Die Kugeln 13 dienen zur Führung der Welle, während die federnde Achse 14 selbst durch die Lauf ringe 16 geführt wird.In the figure, an embodiment of the invention is shown schematically. The shaft 11 is provided with a race 12 for the balls 13 are provided, each of which is arranged on a resilient axle 14. The ends the resilient axes 14 are each provided with a ball 15 that is connected to the machine housing attached barrel rings 16 are mounted. The resilient axes 14 surround the Shaft 11 in the manner of a cylinder jacket. The balls 13 are used to guide the shaft, while the resilient axle 14 itself through the running rings 16 is guided.
Es ist zweckmäßig, den federnden Achsen eine gewisse Vorspannung zu geben, so daß sie keinen geraden Zylindermantel, sondern, wie in der Abbildung dargestellt, eine tonnenförmige Fläche bilden, wodurch erreicht wird, daß die äußeren Kugeln 15 ohne Spiel an ihren Führungsringen 16 aufliegen. Infolgedessen ist es den Kugeln nicht mehr möglich, innerhalb ihrer Führungsringe hin und her zu springen, so daß die störenden Geräusche vermieden werden.It is useful to give the resilient axes a certain preload so that it is not a straight cylinder jacket, but rather a barrel-shaped one, as shown in the figure Form surface, whereby it is achieved that the outer balls 15 without play their guide rings 16 rest. Consequently it is no longer possible for the balls to go back and forth within their guide rings jump forward so that the annoying noises are avoided.
