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.
