Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf doppeltwirkende Stützkugellager mit je einem oder mehreren Kugelsystemen für jede Druckrichtung. Diese Lager haben den Nachteil, daß bei Aufnahme eines Achsialdruckes in einer Richtung das eine Kugelsystem entlastet wird und in achsialer Richtung Spiel erhält, wodurch eine Verlagerung der Kugeln und ein Warmlaufen der Welle verursacht wird.The invention relates to double-acting support ball bearings, each with one or more Ball systems for every pressure direction. These bearings have the disadvantage that when receiving an axial pressure in one direction the one ball system is relieved and receives play in the axial direction, whereby causing the balls to shift and the shaft to warm up.
Um diesen Nachteil zu beseitigen, hat man bereits Federn oder hydraulische Druckausgleicher angeordnet, die das Auftreten des achsialen Spiels verhindern sollen.In order to overcome this disadvantage, springs or hydraulic pressure equalizers are already available arranged to prevent the occurrence of axial play.
Gemäß der Erfindung wird dieser Zweck auf viel einfachere Weise dadurch erreicht, daß die Kugelsysteme in achsialer Richtung etwas größer als der sie aufnehmende Raum des Gehäuses gemacht und vor dem Einsetzen in das Gehäuse achsial zusammengespannt und in diesem gespannten Zustande in das Gehäuse eingesetzt werden. Ein auf diese Weise hergestelltes Lager besitzt infolgedessen stets eine überschüssige . Spannung in achsialer Richtung, die wirksam verhindert, daß bei achsialer Belastung des Lagers in einer Richtung achsiales Spiel im unbelasteten Lagersystem auftritt. According to the invention, this purpose is achieved in a much simpler way by that the spherical systems are somewhat larger in the axial direction than the space they hold made of the housing and axially clamped together and before being inserted into the housing be used in this tensioned state in the housing. One made this way As a result, stock always has an excess. Tension in axial direction, which effectively prevents axial loading of the bearing in one direction Play occurs in the unloaded storage system.
Die Erfindung ist in der Zeichnung an einem Ausführungsbeispiel veranschaulicht, und zwar zeigt Fig. ι einen Achsenschnitt durch das fertige Lager, Fig. 2 einen Teil des Gehäuses im Längsschnitt und Fig. 3 einen Teil der Kugelsysteme im Längsschnitt.The invention is illustrated in the drawing using an exemplary embodiment, namely FIG. 1 shows an axial section through the finished bearing, FIG. 2 shows a part of the housing in longitudinal section and FIG. 3 a part of the ball systems in longitudinal section.
Die aus dem gemeinsamen mittleren Laufring c, den Kugelreihen h, den Außenlaufringen d und den Widerlagerringen e bestehenden beiden Laufrings}rsteme (Fig. 3) besitzen eine Länge b, die im normalen Zustande etwas größer ist als die Länge α der in dem Gehäuse / (Fig. 2) hierfür vorgesehenen Aussparung i. Sie werden vor dem Einsetzen in das Gehäuse f so zusammengepreßt, daß sie in die Aussparung* hineinpassen, so daß sie ständig unter der durch die Elastizität des Materials bedingten Spannung stehen.The two running rings} r systems (FIG. 3) consisting of the common middle race c, the rows of balls h, the outer races d and the abutment rings e have a length b, which in the normal state is slightly greater than the length α of the in the housing / (Fig. 2) provided recess i. Before being inserted into the housing f , they are pressed together so that they fit into the recess * so that they are constantly under the tension caused by the elasticity of the material.
Bei dem dargestellten Beispiel ist das Gehäuse / mit seitlichen Hohlräumen k versehen, die zur Aufnahme der Traglager g für die Welle I dienen.In the example shown, the housing / is provided with lateral cavities k which serve to accommodate the support bearings g for the shaft I.
