Description

Anordnung zur Einstellung des Radialspieles eines Wälzlagers Neuerung Der mxg liegt die Aufgabe zugrunde, eine Anordnung zu schaffen, welche eine Einstellung des Radialspieles eines Wälzlagers entsprechend den jeweils erforderlichen Betriebe ! bedingungen ermöglicht. Die Einstellung des Radialspieles auf einen bestimmten Wert ist in vielen Fällen erwünscht, und zwar insbesondere dann, wenn ein besonders ruhiger Lauf von sich drehenden Teilen gefordert wird. Dies ist beispielsweise bei Kommutatoren elektrischer Maschinen, insbesondere von Bahnmotoren, der Fall, da hierbei Unregelmäßigkeiten im Lauf des Kommutators leicht zu einem Flattern der Bürsten und damit Anlaß zu Störungen geben können. Diese Schwierigkeiten können durch eine Anordnung vermieden werden, welche es gestattet, das Radialspiel des verwendeten Wälzlagers auf einen bestimmten Kleinstwert einzustellen. Neuerung Gemäß der B : Ewg wird die Einstellung des Radialspieles eines Wälzlagers dadurch erreicht, daß der Außenring des im' Lagergehäuse eingebauten Wälzlagers unter dem radial einwir- kenden, in seiner Größe einstellbaren Druck einer Flüssigkeit elastisch verfprmb-r ist. Als Druckflusigkcit kann vor- hehmlich Öl verweMet Werden. Weitere Einzelheiten der Erfindungsind dem in der Figur dargestellten ausführungsbeispiel zu entnehmen. In dem ringförmigen Teil 7 des Lagergehäuses 1 Befindet sich das als Rollenlager ausgebildete Wälzlager 2. In den ringförmigen Teil 7 ist der Ring 4 mit strammem Sitz eingeschoben, welcher an seinen beiden Stirnseiten öldicht mit dem ringförmigen Teil 7 des Lagergehäuses 1 verschweißt ist. Der Ring 4 ist nach dem Verschweißen mit der dem Wälzlager"2 entsprechender Bohrung versehen ; er liegt also unmittelbaren der Außenfläche des Außenringes 3 des-Wälzlagers 2 an. Über den im ringförmigen Teil 7 des Lagergehäuses vorgesehenen Kanal 5 wird die Druckflüssigkeit dem Spalt zwischen dem ringförmigen Teil 7 und dem Ring'4 zugeführt. Der Kanal 5 ist mittels des Rückschlagventils 6 verschlossen.Arrangement for setting the radial play of a Rolling bearing innovation The mxg is based on the task of creating an arrangement create an adjustment of the radial play of a Rolling bearing according to the operations required in each case! conditions enabled. Setting the radial play to a certain value is desirable in many cases, especially when particularly smooth running is required of rotating parts. This is the case, for example, with commutators of electrical machines, in particular rail motors, since irregularities in the course of the commutator can easily cause the brushes to flutter and thus give rise to malfunctions. These difficulties can be avoided by an arrangement which allows the radial play of the roller bearing used to be set to a certain minimum value. innovation According to the B: Ewg, the setting of the radial play is of a roller bearing achieved by the fact that the outer ring of the ' Bearing housing built-in roller bearing under the radially acting kenden, adjustable in its size pressure of a liquid elastic Verprmb-r is. As a pressure fluid kit, good oil be used. More details of the The invention can be found in the exemplary embodiment shown in the figure. In the ring-shaped part 7 of the bearing housing 1 is the roller bearing 2, which is designed as a roller bearing. After welding, the ring 4 is provided with the bore corresponding to the roller bearing "2; it is therefore in direct contact with the outer surface of the outer ring 3 of the roller bearing 2. Via the channel 5 provided in the annular part 7 of the bearing housing, the pressure fluid is fed to the gap between the annular part 7 and the ring 4. The channel 5 is closed by means of the check valve 6.

Der Querschnitt des ringförmigen Teiles 7 des Lagergehäuses ist so stark gewählt, daß dieser Teil unter dem Druck-z. B. 200 atm-der in den Spalt zwischen Teil 7 und Ring 4 hineingepreßten Flüssigkeit keine Verformung erfährt ; vielmehr wirkt sich der Flüssigkeitsdruck lediglich radial nach innen aus, so daß der Ring 4 nach innen eingeengt und damit der Wälzlageraußenring 3 elastisch verformt wird. Auf diese Weise kann, je nach Wahl des Druckes der im Spalt befindlichen Flüssigkeit, das Radialspiel des Wälzlagers 2 auf einen beliebigen Wert eingestellt werden.The cross section of the annular part 7 of the bearing housing is like this strongly chosen that this part under the pressure-z. B. 200 atm-the in the gap between Part 7 and ring 4 pressed liquid does not experience any deformation; much more the fluid pressure only acts radially inward, so that the ring 4 constricted inward and thus the roller bearing outer ring 3 is elastically deformed. In this way, depending on the choice of the pressure of the liquid in the gap, the radial play of the roller bearing 2 can be set to any value.
