Description

Lager für umlaufende Teile an Elektromotoren Bei Kugellagern tritt in vielen Fällen, insbesondere in bestimmten Geschwindigkeitsbereichen, eine Geräuschbildung auf, die wahrscheinlich auf das Springen der Kugeln zurückzufiiliren ist. Urn eine derartige Geräuschbildung zu unterdrücken, ist bereits vorgeschlagen worden, den äußeren Laufring des Kugellagers durch eine Gummischicht abzustützen.Bearings for rotating parts on electric motors in many cases, especially in certain speed ranges, a noise which is probably due to the jumping of the balls. Urn one to suppress such noise has already been proposed to the Support the outer race of the ball bearing with a rubber layer.

Derartige Anordnungen setzen jedoch infolge der 2,Tacligiel)iglteit der Gummischicht ein verhältnismäßig großes Spiel voraus und können daher in vielen Fällen, in denen ein derartiges Spiel nicht zulässig ist, nicht angewendet werden. \acli der Erfindung kann eine Geräuschdämpfung auch bei Anordnungen rnit sehr geringem Spiel, wie beispielsweise bei Motoren mit sehr kleinem Luftspalt, angewendet «-erden, indem gleichfalls eine C@unnni.cliiclit zur Absti.itzun- der Laufringe des Iiugc°Ilager., und zwar im Bedarfsfalle so-%volil des inneren wie des äußeren Laufringes oder auf beiden angewendet v,ird, die aber durch eine Einspannung an einem Ausweichen #erilcreclit zur liclastun-sriclitung verhindert wird. Es ist litierbei die Erkenntnis zugrunde gelegt, daß die Elastizität des Gummis zum größten Teil auf seitlicher Verdrängung beruht, während die Kompressibilität des Materials an und für sich sehr gering ist. Die Gegenwart von Öl oder Fett setzt die Verwendung eines ölfreien Gumniirnaterials, besonders synthetischen Gummis voraus.However, such arrangements set due to the 2, Tacligiel) iglteit the rubber layer is a relatively large game ahead and can therefore be used in many Cases where such play is not allowed will not be used. According to the invention, noise attenuation can also be achieved in arrangements with very little Backlash, such as in motors with a very small air gap, applied «-earth, by also adding a C@unnni.cliiclit for the support of the races of the Iiugc ° Ilager., and in case of need so-% volil of the inner as well as the outer race or on both applied v, ird, but by a restraint on an evasion #erilcreclit to the liclastun-guideline is prevented. It is based on knowledge placed that the elasticity of the rubber is largely due to lateral displacement based, while the compressibility of the material in and of itself is very low. The presence of oil or fat implies the use of an oil-free rubber material, especially synthetic rubbers.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Mit i ist der Laufring eines Kugellagers bezeichnet, mit der äußere Konstruktionsteil, an dem dieser Laufring abgestützt ist. 3 stellt eine dazwischengeschaltete Gummischicht dar, die durch zwei in axialer Richtung gegeneinander abgestützte Wände 4. und an einem seitlichen Ausweichen verhindert wird. In den Konstruktionsteil 2 ist eine Rille eingedreht oder ausgeriornmeri, die annähernd dein Profil der Gummischicht entspricht, so daß die seitliche Abstützung in einer Richtung durch die Begrenzungen dieser Rille erfolgt. In der anderen I',ichtung ist die Abstützung durch einen Ring erreicht, der unter Vorspannung in eine .mit nach Art eines Sprengringes eingeführt ist. Eine andere -Ausführungsform, besonders für gr@)liere Lager. ist in _11)11. 2 dargestellt. i Hierbei ist die Guinniischicht aus drei einzelnen Gulnnlirillgell;. 8 und 9 gebildet, die, ' versetzt gegeneinander angeordnet, iiiit Metall- l ringen in I I.

With i the race of a ball bearing is referred to, with the outer structural part on which this race is supported. 3 shows an interposed rubber layer which is prevented by two walls 4. In the structural part 2, a groove is screwed or aligned, which approximately corresponds to the profile of the rubber layer, so that the lateral support takes place in one direction through the boundaries of this groove. In the other I 'direction, the support is achieved by a ring which is inserted under pretension into a .mit in the manner of a snap ring. Another embodiment, especially for larger bearings. is in _11) 11. 2 shown. i The Guinnia layer is made up of three individual Gulnnlirillgell ;. 8 and 9, which are arranged offset from one another with metal rings i n I I.
