Description
Die Erfindung betrifft eine Wälzlageranordnung und ein Druckwerk einer Druckmaschine mit der Wälzlageranordnung.The The invention relates to a roller bearing assembly and a printing unit of a printing machine with the rolling bearing assembly.

Eine Aufgabe der Erfindung ist es, eine Wälzlageranordnung zu schaffen, mit der insbesondere beim Einbau von Druckzylindern von Druckmaschinen höchste Genauigkeitsanforderungen hinsichtlich eines einzustellenden Lagerspiels und einer Rundheit der Lagerringe einfach und kostengünstig erfüllt werden können.A The object of the invention is to provide a roller bearing assembly, with the particular in the installation of printing cylinders of printing machines highest Precision requirements with regard to a bearing clearance to be set and a roundness of the bearing rings are easily and inexpensively met can.
Die Aufgabe wird durch den Gegenstand der Patentansprüche 1 und 6 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.The The object is achieved by the subject matter of patent claims 1 and 6 solved. Advantageous embodiments are described in the subclaims.
Gemäß Anspruch 1 beinhaltet eine Wälzlageranordnung folgende Merkmale:
- – Ein Innenring, ein Mittenring und ein Außenring, dessen Außenmantel einen kegelstumpfmantelartigen Bereich aufweist,
- – zwischen dem Innenring und dem Mittenring angeordnete erste Wälzkörper und zwischen dem Mittenring und dem Außenring angeordnete zweite Wälzkörper,
- – eine im wesentlichen um den Außenring herum angeordnete Hülse, deren Innenmantel passend zu dem kegelstumpfmantelartigen Bereich des Außenrings einen kegelstumpfmantelartigen Bereich aufweist, und
- – zwischen der Hülse und dem Außenring wirkende Mittel für ein gegeneinander gerichtetes Verschieben von Hülse und Außenring.
- An inner ring, a center ring and an outer ring, the outer shell of which has a frustoconical area,
- - arranged between the inner ring and the center ring first rolling elements and arranged between the middle ring and the outer ring second rolling elements,
- A sleeve arranged substantially around the outer ring, the inner jacket of which has a truncated cone-shaped area matching the frustoconical area of the outer ring, and
- - acting between the sleeve and the outer ring means for a mutually directed displacement of sleeve and outer ring.
Dadurch, dass über die zueinander passenden kegelstumpfmantelartigen Bereiche die Hülse und der Außenring beim Einbau der Wälzlageranordnung in ein entsprechendes Lagergehäuse gegeneinander verschiebbar sind, ist dadurch eine Außendurchmesser der Wälzlageranordnung im Mikrometerbereich elastisch verformbar und damit eine mikrometergenaue Passung der Wälzlageranordnung im Lagergehäuse kontrollierbar, worüber eine radiale Lagerluft bzw. Vorspannung der Wälzlagerung gezielt einstellbar ist. Damit entfällt beispielsweise bei Druckmaschinen ein bislang nötiges mikrometergenaues Zusortieren von Wälzlageranordnungen für Druckzylinder zu den die Wälzlageranordnungen aufnehmenden Seitenwänden, um im Einbaufalle eine Überdeckung oder ein Spiel in der Größenordnung von beispielsweise 10 μm zu haben. Gemäß der Erfindung ist dies nun durch ein Verschieben von Hülse zu Außenring einstellbar. Weiterhin ist damit eine Montage- und Austauschfreundlichkeit deutlich erhöht.Thereby, that over the mating frusto-conical regions of the sleeve and the outer ring when installing the rolling bearing assembly in a corresponding bearing housing are mutually displaceable, thereby an outer diameter the rolling bearing assembly In the micrometer range elastically deformable and thus a micrometer accurate Fit the rolling bearing assembly in the bearing housing controllable, over what a radial clearance or preload the rolling bearing selectively adjustable is. This is eliminated For example, in printing presses a hitherto necessary micrometer accurate Zusortieren of rolling bearing arrangements for printing cylinders to the rolling bearing arrangements receiving side walls, to overlap in the installation hall or a game of the order of for example, 10 microns to have. According to the invention this is now adjustable by moving from sleeve to outer ring. Farther Thus, a mounting and exchange friendliness is significantly increased.
Dadurch, dass die Hülse in Umfangsrichtung mit einer definierten Unrundheit ausgebildet ist, können insbesondere beim Einbau von Wälzlageranordnungen für Druckzylindern in die Wälzlageranordnungen aufnehmenden Seitenwände Koaxialfehler sowie niedrige Formfehler ausgeglichen werden, wodurch ein dafür bisher notwendiges, aufwendiges Schaben der Aufnahmeöffnungen für die Wälzlageranordnungen in den Seitenwände entfällt. Dies ist insbesondere bei zwei, drei oder mehr übereinander gestapelten Druckzylindern von besonderem Vorteil, da insbesondere die unteren Seitenwandaufnahmeöffnungen durch den Druck der darüber liegenden Druckzylinder oval verformt werden. Insbesondere bei einem mittels eines Dreiringlagers gelagerten Druckzylinders, bei dem das innere Wälzlager als ein im Vorspannbereich betriebenes Zylinderrollenlager ausgebildet ist, ist damit eine Zylinderrollenlaufbahn absolut korrekt und präzise rund einstellbar, so dass sich ein gutes Druckbild ergibt, jede Formerregung reduziert und die Lebensdauer optimiert wird. Dabei können bei Dreiringlagern alternativ oder ergänzend zu der in Umfangsrichtung unrunden Hülse zum Ausgleichen der Koaxialitäts- und niedrigen Formfehlern die Wälzkörper des zweiten, beispielsweise als Nadel lager ausgebildeten Wälzlagers, insbesondere hinsichtlich ihrer Durchmesser unterschiedlich sortierte Nadeln beinhalten.Thereby, that the sleeve formed in the circumferential direction with a defined out-of-roundness is, can especially when installing rolling bearing assemblies for printing cylinders in the rolling bearing arrangements receiving side walls Coaxial errors as well as low form errors are compensated, thereby one for that previously necessary, consuming scraping the receiving openings for the Rolling arrangements in the sidewalls eliminated. This is especially true for two, three or more stacked printing cylinders particularly advantageous, since in particular the lower side wall receiving openings by the pressure of it lying printing cylinder are deformed oval. Especially with a By means of a three-ring bearing mounted pressure cylinder in which the inner rolling bearing designed as a operated in the biasing cylindrical roller bearing is, so that a cylindrical roller bearing is absolutely correct and precise round adjustable, resulting in a good print image, reduces any form of excitation and the lifetime is optimized. It can be used in three-ring bearings alternatively or in addition to the circumferentially non-round sleeve for balancing the coaxial and low form errors the rolling elements of the second, for example, designed as a needle bearing bearing, sorted differently in particular with regard to their diameters Needles include.
