Description
Einstellbares Wälzlager nie Erfindung betrifft ein einstellbares Wälzlager mit einem balligen Außenring, der in einer entsprechenden hohikugeligen Ausnehmung eines Lagerträgers aufgenommen i3t.Adjustable roller bearing The invention never relates to an adjustable roller bearing with a spherical outer ring which is in a corresponding hollow spherical recess of a bearing bracket added i3t.
Derartige einstellbare Wälzlager werden verwendet, um kleine Schwenkbewegungen des Lagers im Lagerträger zu ermöglichen, beispielsweise bei Durchbiegungen der Welle. Bei Einbaufällen, bei denen ein großes Wärmegefälle zwischen Wälzlager und Lagertragerentsteht, besteht die Gefahr, daß sich das Lager im Lagerträger verklemmt, Dieses Problem tritt insbesondere bei Trocknern für Papiere, Kunststoffe oder Textilien auf.Such adjustable roller bearings are used to make small pivoting movements to enable the bearing in the bearing bracket, for example when the Wave. For installation cases where there is a large heat gradient between the roller bearing and Bearing bracket arises, there is a risk that the bearing will jam in the bearing bracket, This problem occurs in particular with dryers for paper, plastics or textiles on.
Die Walzen derartiger Trockner sind in Wälzlagern gelagert, deren lagerträger außerhalb des Gehäuses angebracht sind. Die Wälzlager wzrden dabe' iber t heißen Wellen stärker aufgeheizt als ihre Lagerträger.The rollers of such dryers are mounted in roller bearings, their bearing supports are attached outside of the housing. The rolling bearings would also be included t hot shafts are more heated than their bearing brackets.
Die daraus entstehende größere thermische Ausdehnung des Wälzlagers kann zu einer Verklemmung im Lagerträger führen, so daß sich das Lager nicht mehr eir stellen kann. Um dies zu vermeiden, mußte meil das Spiel zwischen Lager und Lagerträger im kalten Zustand so groß wählen, daß im Betrieb die Einstellbarkeit des Lagers noch möglich war. Da jedoch die bei den einzelnen Betriebszuständen auftretenden Temperaturen sehr unterschiedlich sind, konnte auf diesem Wege keine Lösung gefunden werden, die bei allen auftretenden Temperaturunterschieden zufriedenstellend war.The resulting greater thermal expansion of the rolling bearing can lead to a jam in the bearing bracket, so that the bearing is no longer eir can provide. In order to avoid this, there had to be a clearance between bearings and Select the bearing bracket in the cold state so large that it can be adjusted during operation of the camp was still possible. Since, however, the occurring in the individual operating states Temperatures are very different, no solution could be found in this way which was satisfactory for all temperature differences that occurred.
Die Erfindung hat sich die Aufgabe gestellt, hier Abhilfe zu schaffen und es wird erfindungsgemäß vorgeschlagen, daß zur Aufnahme unterschiedlicher thermischer Ausdehnungen des lagers und des Lagerträgers zwischen dem Außenring des Lagers und der Ausnehmung des Lagerträgers eine gleitfähige Gewebeschicht angeordnet ist.The invention has set itself the task of remedying this and it is proposed according to the invention that to accommodate different thermal Expansions of the bearing and the bearing bracket between the outer ring of the bearing and a slidable fabric layer is arranged in the recess of the bearing carrier.
Diese Gewebeschicht weist zweckmäßigerweise eine Dicke zwischen 0,4 und 0,5 mm auf. Sie nimmt die unterschiedliche thermische Ausdehnung von Lager und Lagerträger auf und gewährleistet bei allen im Betrieb auftretenden Temperaturunterschieden die einwandfreie Einsteilbarkeit des Wälzlagers.This fabric layer expediently has a thickness between 0.4 and 0.5 mm. It takes the different thermal expansion of bearings and Bearing carrier on and guaranteed for all temperature differences occurring during operation the flawless adjustability of the rolling bearing.
Nacn einer vorteilhaften Ausführungsform der Erfindung kann die Gewebeschicht aus einem Polytetrafluoräthylen-Kunststoff bestehen. Die Gewebeschicht kann auf den Außenring des Wälzlagers oder in die Ausnehmung des Jagertragers geklebt sein.According to an advantageous embodiment of the invention, the fabric layer consist of a polytetrafluoroethylene plastic. The fabric layer can be on the outer ring of the roller bearing or glued into the recess of the hunter carrier.
Die beigefügte Zeichnung zeigt als Ausführungsbeispiel einen Längsschnitt durch ein einstellbares Kugellager, das in einem Lagerträger aufgenommen ist.The accompanying drawing shows a longitudinal section as an exemplary embodiment by an adjustable ball bearing, which is received in a bearing bracket.
Das drgesteilte Kugellager besteht aus einem Innenring 1, der auf die Welle 2 aufgeschoben und mit dem Spannring 3 gesichert ist. Der Außenring 4 des Kugellagers weist eine ballige Mantelfläche auf und ist in einer hohlkugeligen Ausnehmung des Lagertragers 5 aufgenommen. Zwischen deni Außenring 4 und der Ausnehmung des Lagerträgers ist die Gewebeschicht 6 angeordnet, die die thermische Ausdehnung des Außenrings aufnimmt.The three-part ball bearing consists of an inner ring 1, which is on the shaft 2 is pushed on and secured with the clamping ring 3. The outer ring 4 of the ball bearing has a spherical outer surface and is in a hollow spherical Recess of the bearing carrier 5 was added. Between the outer ring 4 and the recess of the bearing carrier is the fabric layer 6, which allows the thermal expansion of the outer ring.
