Definitions

  • the invention relates to a drum for carding machines, the jacket is made of sheet steel and is supported at its ends against a hub fastened to the drive shaft.
  • Drums and rollers which are used to convey, process and process fiber material in textile machines, consist of a wide variety of materials.
  • the materials mentioned have their own disadvantages.
  • Casting rollers in particular have a high weight and, in addition to the great effort required for repair and maintenance work, require a high proportion of power to drive them.
  • steel card drums are considerably lighter and therefore have the disadvantages listed above to a much lesser extent. Nevertheless, steel drums have so far not been able to be put into practical use.
  • One of the main causes is the insufficient dimensional stability in the static and dynamic state, especially when carding with the high speeds of these drums that are common today and with larger widths.
  • the carding drums which usually consist of a jacket that is supported on the shaft by means of crosses of spokes at its ends and hubs, therefore have ring-like ribs, distributed over the length of the jacket, for reinforcement. This has resulted in satisfactory dimensional stability in cast drums 2 u, but this construction has not proven itself in steel rollers.
  • Aulcabe of the present invention is to provide a drum with a sheet steel jacket for carding machines, which has a high dimensional stability and keeps it even at high speeds.
  • the object is achieved in that the drum is divided into cells by radial support elements connected to the jacket of the drum.
  • the hub consists of a central tube connecting the two hubs, against which the support elements are braced.
  • the support elements are supported directly on the drive shaft.
  • the support elements are designed as steel disks which are welded to the drum shell and the central tube.
  • Support elements which are supported directly on the drive shaft can also be designed as cast crosses which are each connected to the casing of the drum and the drive shaft.
  • a cell construction of the drum in which the width of the cells is in a ratio of 1: 4 to 1: 6 to the diameter of the drum has proven to be particularly expedient.
  • An improvement in the axial rigidity of the drum is achieved in that the steel disks are supported in the axial direction against the central tube.
  • the steel disks are provided with openings. Because the drum is fastened to the drive shaft by means of tensioning elements, it can be applied to the drive shaft without tension.
  • Flanges are expediently provided which accommodate the drum on the steel disks. 2 to prevent u, that the drum moves especially when a sudden braking in the direction of adjacent working units, in addition, the drive shaft supporting the drum from the center.
  • the drum 1 shown in Figure 1 has a jacket 10 which consists of sheet steel.
  • radial support elements 2 are arranged, which are connected to the casing 10 of the drum 1 and a drive shaft 3 on which they are supported.
  • the jacket 10 is supported at both ends against a hub 30 and 31 fastened to the drive shaft 3.
  • the drum 1 is expediently fastened to the drive shaft 3 by means of tensioning elements 32.
  • the interior of the drum 1 is divided into cells 4 of the same width by the support elements 2, which are arranged at the same distance from one another and can be designed as cast crosses. It has proven to be particularly favorable with regard to the dimensional stability if the width of the cells 4 is in a ratio of 1: 4 to 1: 6 to the diameter of the drum 1.
  • the drum has a central tube 5 as the hub, which extends over the support length of the casing 10 and thus connects the two hubs 30 and 31 from FIG. 1 to one another.
  • the support elements 2 are designed here as steel disks, which are supported on the central tube 5.
  • the steel disks which can be provided with openings 20 to reduce weight, are welded to the steel sheet jacket 10 and the central tube 5.
  • the connection of the steel disks to the jacket 10 is preferably carried out without gaps over the entire circumference of the steel discs.
  • the drum 1 is received by flanges 6, which are fastened to the outer steel disks, and connected in a rotationally fixed manner to the drive shaft 3 by means of tensioning elements 32.
  • the tensioning elements 32 can be ring springs, for example.
  • the steel disks serving as support elements 2 also divide the interior into cells of the same width in this embodiment.
  • This design provides the drum 1 with a high dimensional stability that approximates that of a full body, which is retained even with large centrifugal forces and ensures a corresponding concentricity.
  • a support 7 for the drum 1 is provided in the center of the central tube 5 for further stiffening, in particular in the case of oversized carding machines, and to prevent the drum from moving in the direction of the adjacent carding members when the brakes are severely braked. Furthermore, in order to improve the rigidity of the drum 1 in the axial direction, it may also be expedient to support the steel disks against the central tube 5. This can be done by ribs 8, struts or the like.
