Description
Blegungsarme Walze Die Erfindung betrifft Walzen, wie sie an Maschi nen der Textil-, Kunststoff- und Druckerei-Industrie als Press-, Druck-Stützwalzen und ähnlichen verwen det werden, und die auch bei hoher Belastung nur eine sehr geringe Durchbiegung aufweisen dürfen.
Bei einer schon bekannten Ausführung einer ble- gungsarmen Walze wird der gewünschte Effekt da durch erreicht, dass die auf die Walze ausgeübte Belastung auf ein hydraulisches Polster übertragen wird, welches seinerseits diese Belastung wieder auf einen Träger, dessen Durchbiegung dann auf die Funk tion der Walze keinen Einfluss mehr ausübt, weiterlei tet. Diese Anordnung stellt entsprechend ihrer kon struktiven Ausbildung hohe Anforderungen an die Ge nauigkeit der Herstellung und erfordert ein hydrau lisches System, was vielfach nicht erwünscht ist.
Diese Nachteile sind durch die erfindungsgemässe biegungsarme Walze dadurch behoben, dass der zylin drische Walzenmantel an mindestens zwei Stellen durch um eine Achse oder Welle angeordnete, wip- penartige Organe abgestützt ist.
In der Zeichnung sind zwei beispielsweise Aus führungsformen von biegungsarmen Walzen nach der Erfindung im unbelasteten Zustand dargestellt. Es zeigen: Fig. <B>1</B> im Schnitt nach der Linie<B>1-1</B> der Fig. 2 und Fig. 2 im Schnitt nach der Linie II-II der Fig. <B>1</B> eine biegungsanne Walze, welche an vier Stellen abge stützt ist,
Fig. <B>3</B> im Schnitt nach der Linie III-III der Fig. 4 und Fig. 4 im Schnitt nach der Linie IV-IV der Fig. <B>3</B> eine biegungsarme Walze, welche an acht Stellen ab gestützt ist.
Gemäss Fig. <B>1</B> sind auf einer Achse oder Welle<B>1</B> mit beliebig ausgebildetem Querschnitt, aus Lager- innenkörpern. 2 und aus Montagegründen zweiteilig ausgeführten Lageraussenkörpern <B>3</B> bestehende sphä rische Lager angeordnet. Die Lagerinnenkörper 2 sind mit der Achse<B>1</B> und eine Hälfte der Lageraussen- körper <B>3</B> sind mit eine Wippe bildenden Rohren 4 fest verbunden. An den beiden Enden sind die Rohre 4 durch Ringe<B>5</B> verstärkt, welche die Stützstellen für den Walzenmantel<B>6</B> bilden.
Wird nun der Walzenmantel<B>6</B> durch äussere Kraftwirkung entlang einer Tangente belastet, über trägt sich diese Belastung zunächst auf die als Stütz stellen dienenden Ringe<B>5</B> der Rohre 4, welche diese dann über die aus den Lagerkörpern 2 und<B>3</B> bestehenden sphärischen Lager auf die Walzenachse<B>1</B> ableitet. Die dabei entstehende Durchbiegung der als Wippen die nenden Rohre 4 sowie der Achse<B>1</B> selbst hat keinen Einfluss auf den Walzenmantel<B>6,</B> der infolge seiner 4fachen Abstützung nur eine sehr geringfügige Durch- biegung erfährt.
Bei Maschinen, welche an die Wal zenstabilität besonders hohe Anforderungen stellen, oder bei Walzen von ungewöhnlich grosser Arbeits länge kann die Stabilität durch Anordnung weiterer Stützstellen, wie in den Fig. <B>3</B> und 4 dargestellt, noch erhöht werden.
Bei dieser Ausführung wird die Belastung des Walzenmantels<B>6</B> über die Ringe<B>5</B> auf die als Wippen dienenden Rohre 4 abgeleitet. Diese übertragen die Belastung über die aus den Lagerkörnern 2 und<B>3</B> gebildeten sDhärischen Lager auf eine Zwischenwipve bildende Rohre<B>9,</B> welche diese nun über LaLyerköri)er <B>10</B> und<B>11</B> auf die Walzenachse<B>1</B> abführen. Die dabei entstehende Durchbiegung der als Wivpe verwende ten Rohre 4 und<B>9</B> sowie der Walzenachse<B>1</B> bleibt ohne Einfluss auf die Stabilität des Walzenmantels<B>6,</B> die durch die gfache Abstützung ausserordentlich hoch ist.
The invention relates to rollers such as those used on machines in the textile, plastics and printing industries as press, pressure backup rollers and the like, and which are only allowed to have a very low deflection even under high loads.
In an already known design of a low-deformation roller, the desired effect is achieved in that the load exerted on the roller is transferred to a hydraulic cushion, which in turn transfers this load to a carrier, the deflection of which then affects the function of the roller no longer exerts any influence. This arrangement makes high demands on the accuracy of the production and requires a hy metallic system, which is often undesirable.
These disadvantages are eliminated by the inventive roller with little bendability in that the cylindrical roller jacket is supported at at least two points by rocker-like members arranged around an axis or shaft.
In the drawing, two exemplary embodiments of low-bending rollers according to the invention are shown in the unloaded state. They show: FIG. 1 in section along line 1-1 in FIG. 2 and FIG. 2 in section along line II-II in FIG 1 </B> a flexible roller, which is supported in four places,
FIG. 3 shows a section along the line III-III of FIG. 4 and FIG. 4 shows a section along the line IV-IV of FIG is supported in eight places.
According to FIG. 1, there are inner bearing bodies on an axle or shaft, with a cross section of any design. 2 and for reasons of assembly two-part bearing outer bodies <B> 3 </B> arranged existing spherical bearings. The inner bearing bodies 2 are firmly connected to the axis <B> 1 </B> and one half of the outer bearing bodies <B> 3 </B> are firmly connected to tubes 4 which form a rocker. At the two ends, the tubes 4 are reinforced by rings <B> 5 </B>, which form the support points for the roll shell <B> 6 </B>.
If the roll shell <B> 6 </B> is now loaded by the external force effect along a tangent, this load is initially transferred to the rings <B> 5 </B> of the tubes 4, which serve as support points, which these then over the derives from the bearing bodies 2 and <B> 3 </B> existing spherical bearings on the roller axis <B> 1 </B>. The resulting bending of the tubes 4, which act as rockers, as well as the axis <B> 1 </B> itself has no influence on the roll shell <B> 6, </B> which only has a very slight deflection due to its fourfold support learns.
In the case of machines which place particularly high demands on the roll stability, or in the case of rolls with an unusually large working length, the stability can be increased by arranging additional support points, as shown in FIGS. 3 and 4.
In this embodiment, the load on the roller jacket <B> 6 </B> is diverted via the rings <B> 5 </B> onto the tubes 4 serving as rockers. These transfer the load via the spherical bearings formed from the bearing grains 2 and 3 to a tube 9, which forms an intermediate wipve, which these now through LaLyerköri 10 / B > and <B> 11 </B> onto the roller axis <B> 1 </B>. The resulting bending of the tubes 4 and 9 used as Wivpe as well as the roller axis <B> 1 </B> has no effect on the stability of the roller jacket <B> 6 </B> the gfache support is extraordinarily high.
