Definitions

  • the invention relates to a drivable roller with controllable deflection, in particular for machines for producing and processing webs of paper or plastic.
  • rollers with controllable deflection are known per se.
  • a roller is described in DE-OS 28 37 913, which has an essentially cylindrical inner part which is fixedly supported on an abutment by means of axle journals, and a tubular outer part which surrounds the inner part and which is rotatable about its cylinder axis Both ends are mounted on the inner part, with a device for generating constraining forces effective in the radial direction between the inner part and the outer part being arranged along a surface line on the inner part.
  • a deflection of the inner part is achieved by heating the inner part on one side, which deflection is transmitted to the outer part via the mounting of the outer part on the inner part.
  • DE-AS 20 50 696 describes a roller intended for high bending loads, in which a drive shaft mounted in the vicinity of its outer end on the axle journal is guided coaxially through one of the axle journals and is connected to a central wheel, which is connected via a Gear unit mounted on the inner part drives an inner ring gear arranged coaxially with the outer part and drivingly connected to it.
  • the gear transmission has two intermediate wheels arranged diametrically to the central wheel, which mesh through the slots in the axle pin and mesh with the inner ring gear, which is attached to the end faces of the outer part of the roller from the outside and is fastened there.
  • the central wheel shaft is not mounted on the inner part of the roller, but is only connected to the drive shaft via an articulated coupling.
  • certain spacing conditions between the center point of the central wheel and on the one hand the articulation point of the coupling and on the other hand the center point of the self-aligning bearing between the outer part and the inner part of the roller must be observed.
  • the known roller has the disadvantage that the construction is quite complex, with the double slitting of the inner part for the passage of the two intermediate gears a strong weakening which limits the maximum load must be accepted, or these components must be over-dimensioned. Furthermore, the transferable speed and thus the possible transmission ratio of the gear transmission is limited by the connection of the central wheel via an articulated coupling to the drive shaft. The central wheel must be made relatively large, which on the one hand causes high manufacturing costs and on the other hand also requires a corresponding dimensioning of the axle journal. This design effort is further increased by the fact that, due to the limitation of the transmission ratio, relatively high torques have to be transmitted to the transmission via the drive shaft and clutch.
  • the invention relates to a drivable roller with controllable deflection, in particular for machines for the production and processing of webs of paper or plastic, with an essentially cylindrical inner part, which is firmly attached to a counter via axle journals Bearing is mounted and a tubular, the inner part surrounding the inner part, which is rotatable about the cylinder axis, is supported at its two ends on the inner part, wherein on the inner part along a surface line a device for generating radial forces acting between the inner part and the outer part is arranged , and in which a drive shaft, which is mounted in the vicinity of its outer end on the axle journal and is coaxially guided through one of the axle journals, is connected to a central gear which, via a gear transmission mounted on the inner member, has an inner gear ring arranged coaxially with the outer member and drivingly connected to it drives.
  • the object underlying the invention was to improve a drivable roller with controllable deflection of this type so that a drivable roller is obtained with very little design effort, which achieves high line pressures and thus high loads even with small roller diameters and especially small journal diameters allowed, in the deflection of the outer part do not cause a malfunction of the drive and in which no special measures for setting and maintaining a certain adjustment need to be taken.
  • the drive shaft is mounted at its inner end on the inner part and the central wheel is integrally connected to the drive shaft
  • the gear transmission has a single idler gear, the axis of rotation of which is fixed parallel to the axis of the drive shaft sets, and the teeth of which each have a crest that slopes down towards the end faces in the direction of its axis of rotation
  • the inner ring gear is pushed into the outer part and is non-positively connected to the inner surface of the outer part via tensioning elements.
  • the gear transmission can consist of a single idler gear, with the result that the journal or inner part is weakened only at one point, namely the passage of this single idler gear.
  • This and the omission of the coupling to be arranged in the journal in the known device have the consequence that both the journal and the central wheel can be dimensioned relatively small.
  • a large saving of material and simplification of construction results from the fact that the central wheel can then be machined out of one piece with the drive shaft.
  • the gear ratio between the central gear and the internal ring gear can be selected to be relatively high, which means that only small torques have to be transmitted via the drive shaft, since high input speeds and correspondingly inexpensive motors for high speeds can be used.
  • the deflections of the outer part are compensated for in a simple manner by the special curved design of the tooth combs on the idler gear.
  • roller according to the invention enables a large saving in drive energy with a low design effort and runs extremely quietly even at high speeds.
  • two clamping rings which are plugged into one another and have conical, slotted outer surfaces, abut one another and are arranged between the internal ring gear and the inner surface of the outer part and rest with their inner end face on a stop connected to the outer part , while the outer end face is under the action of force of an adjusting ring inserted into the outer part and displaceable in the longitudinal direction of the outer part by means of adjusting screws.
  • the thickness of the toothed rim is greater than the thickness of the idler gear. This ensures that there are no transmission problems even when the outer part of the roller bends more than the central axis of the drive shaft.
  • the drive shaft, central gear, idler gear and internal ring gear are inside an In sealed with respect to liquid passage nenraumes arranged, which is connected to at least one lubricant supply line and a lubricant discharge line.
  • the drive elements of the roller are arranged in a space-saving manner in an interior with a relatively small volume, this interior being well sealed against the exterior and connected to circulating lubrication. This brings considerable advantages, in particular to achieve high speeds, which are required for machine speeds from approximately 400 m / min. required are.
  • roller with controllable deflection is shown in a longitudinal section.
  • the roller has a substantially cylindrical inner part 1, which ends in a journal 2 at both ends.
  • the journal 2 shown is hollow and has a continuous interior 2a which opens into a recess 1a of the inner part 1.
  • the journal 2 is supported on a fixed abutment 5.
  • a tubular outer part 3 is supported via roller bearings 4, on the outer surface of which a special roller shell 3a is arranged.
  • the roller bearing 4 is a spherical roller bearing. There are further such spherical roller bearings, not shown, arranged in the longitudinal direction of the roller. Furthermore, is on the inner part 1 in a manner not shown along a surface line is arranged a device for generating in the radial direction between the inner part and outer part of the constraining forces by which the deflection is achieved in a controllable manner. Such a device can be designed, for example, as described in DE-OS 28 37 913.
  • a drive shaft 6 is passed through the interior 2a of the journal 2, which is supported at its outer end via a ball bearing 7 on the journal 2, while at the other end via a further ball bearing 8 and a ball bearing 9 on the inner part 1 is stored.
  • a central wheel 10 is arranged, which has a relatively small diameter and is integrally connected to the drive shaft 6.
  • the central wheel 10 meshes with an intermediate wheel 11 which is mounted above the central wheel 10 via ball bearings 13 on an axis 12 arranged on the inner part 1.
  • the intermediate gear 11 in turn meshes with an inner ring gear 14 which is inserted into the outer part 3 and is non-positively connected to the inner surface of the outer part 3 via two clamping rings 15a and 15b.
  • the clamping ring 15a lies with its end face facing the inside of the roll against a stop 14a which is connected to the internal ring gear 14.
  • the clamping ring 15a rests on the likewise conical outer surface of the other clamping ring 15b, the outward-facing end face of which rests on an adjusting ring 16 attached from the outside, which is connected to the internal ring gear 14 by means of adjusting screws 17.
  • the adjusting ring 16 is displaceable in the longitudinal direction.
  • the two wedge-shaped clamping rings 15a and 15b can be displaced relative to one another, and the contact pressure between the internal ring gear 14 and the outer part 3 can thus be changed in an adjustable manner.
  • the two clamping rings 15a and 15b are suitably slotted in a manner not shown in order to prevent jamming.
  • the teeth 11a of the intermediate wheel 3, whose axis of rotation Z are arranged parallel to the axis of rotation M of the drive shaft 6, are fixed. is provided with tooth combs which are curved in the direction of the axis of rotation Z, i.e. the height of the tooth combs increases from the central plane of the intermediate gear 11 to both end faces.
  • the transmission ratio between the central wheel 10 and the internal ring gear 14 can be selected to be relatively high and, for example, 1: 5. In this way, an electric motor with a relatively high speed can be connected to the outer end of the drive shaft 6.
