Definitions

  • the invention relates to a guide roller for web material according to the preamble of claim 1.
  • a guide roller is also known (DE-AS 11 78 257) which has two outer tube sections and a central tube section arranged between them.
  • the outer pipe sections are supported on a central axis via roller bearings.
  • the mutually adjacent ends of the one part of the outer tube sections and the other part of the spectral zen ⁇ pipe section enclose one another and are rotationally connected to each other.
  • the pipe sections are supported by roller bearings in the encompassing area.
  • the outer tube sections are at ih ⁇ ren outer ends non-radially relative to the axis ver ⁇ adjustable.
  • spreader rolls which only serve to spread out the web material.
  • Such known expander rollers have a plurality of individually gelager ⁇ th and disposed in an arc tube sections, which are also all rotationally fixed manner via couplings joined together. It is also already known to provide all pipe sections with slots which extend over a partial circumference and are offset with respect to one another and thus to form the pipe sections elastically.
  • the object of the invention is to create a guide roller which can also have a spreading function and which requires a relatively low drive power.
  • the guide roller according to the invention has a spreading function in addition to a guide function and can therefore be used universally.
  • FIG. 1 - a partially cut side view of the guide roller according to the invention
  • Figure 2 - a view similar to figure 1 showing the routing ⁇ roller with an elastic coating.
  • a central axis 3 is provided, on which a central tube section 1 is mounted via two roller bearings 5 each provided at the ends la, which have their inner ring on the bearing bushes 9 surrounding the axis 3. Only the right storage area is shown in the drawing. Adjacent to the central pipe section 1, outer pipe sections 2 and 2 'are provided, the arrangement and mounting and actuation of which are mirror-symmetrical.
  • the outer tube section 2 is supported with its outer end on a sleeve 20 via two roller bearings 6, 7.
  • the sleeve 20 lies adjacent to the roller bearing 5 with its inner diameter on the outer circumference of the axis 3 and is supported on it with an O-ring 15.
  • the sleeve 20 is designed such that it surrounds the axis 3 and a region 3b with a reduced diameter at a distance. This distance is dimensioned so large that radial adjustment can take place via the threaded spindle 4.
  • the threaded spindle 4 has a threaded region 4a which is screwed into a thread 3a which passes through the axis 3 transversely.
  • the screw 4 passes through the sleeve 20 and is supported against their ⁇ about immovably. Twisting the threaded spindle 4 causes the sleeve 20 to pivot relative to the axis 3.
  • the sleeve 20 is enclosed at its outer end by a bearing bush ⁇ se 21, on which the roller bearings 6 and 7 are supported.
  • the roller bearings 6, 7 are received in a bearing bush 22 which carries the pipe section 2 at its outer end.
  • the end 1 a of the central pipe section 1 is reduced in diameter and is overlapped by the inner end 2 a of the outer pipe section 2. This results in a gapless transition between the pipe sections 1, 2 or 1, 2 '.
  • the roller bearing 5 is arranged under the ends la, 2a forming the encompassing area.
  • the outer tube section 2 is designed to be elastic in such a way that it bends in an arcuate manner due to the pivoting of the sleeve 20.
  • the outer tube sections 2, 2 ' can also be provided with slots 2b, as is shown on the outer tube section 2' on the left in FIG.
  • the slots extend over a partial circumference of the outer tube section 2 '.
  • Two adjacent slots are offset from one another in the circumferential direction.
  • the adjacent pipe sections 1, 2 and 1, 2 ' are glued or screwed together.
  • the guide roller as shown in FIG. 2, is provided with a rubber covering 23, a separate connection of the adjacent pipe sections 2 ', 1, 2 may be omitted, if necessary, because the rubber covering 23 pipe sections 2, 1 and 2' are all non-rotatable with one another connects.
  • the outer surfaces of all pipe sections are aligned with one another.

Abstract

L'invention concerne un rouleau-guide pour matériau sous forme de bande, notamment pour machines à papier. Ce rouleau-guide comprend deux sections tubulaires (2; 2') extérieures et éventuellement au moins une section tubulaire (1) montée entre. Les sections tubulaires (1, 2; 2') sont soutenues sur un axe central (3) par l'intermédiaire de paliers à roulement (5; 6, 7) et les sections tubulaires (2; 2') sont déplaçables dans le sens radial par rapport audit axe (3). Les extrémités (1a; 2a) adjacentes les unes aux autres de sections tubulaires (1; 2) adjacentes s'enserrent mutuellement et sont interconnectées directement de manière à ne pas tourner. Les paliers à roulement (5) sont placés en dessous de la zone où lesdites sections s'enserrent (1a; 2a) et les sections tubulaires (2; 2') extérieures sont formées élastiques dans le sens longitudinal.
