Definitions

  • the invention relates to a method for producing a paddle wheel body with a support body formed from a single sheet metal, which is approximately frustoconical in cross section, in particular for use in opencast mining equipment.
  • a cellless impeller with a conically shaped support body is known, which is rotatably mounted on the impeller axis and to which an annular body carrying the blades is attached.
  • the support body consists of a disc that can be produced in one operation by rolling.
  • this type of shaping can essentially be seen in the fact that only contours can be created in one direction, starting from the center of the paddle wheel, so that a number of welding jobs (introducing stiffeners or the like) are required to provide the necessary stability. must be carried out. This measure increases the total weight of the impeller body.
  • Another disadvantage is the likewise complex displacement of the buckets on the outer circumference of the paddle wheel body, which also has to be brought about by welding.
  • EP-A-148 066 and DE-A-32 15 029 show processes for the production of steel or aluminum wheels for vehicles, a disc being used as the base material. This disk is shaped into a cylindrical pot by deep drawing. In the same or a different shape, the pot is brought into its final shape by a further deep-drawing process.
  • the invention is based on the object of designing a method for producing a blade wheel body, by means of which the complex welding work can be reduced to a minimum without adversely affecting the rigidity of the blade wheel body. Furthermore, a paddle wheel body is to be designed which is easy and inexpensive to produce, the welding work which is still necessary should be more accessible for any repair purposes.
  • the measures according to the invention can be used to produce a finished blank which consists of the frustoconical support body and at least the molded ring carrier. Welding work to form the ring carrier can be completely avoided. Compared to St. d. T. is presented here a paddle wheel body, which is not only much easier to manufacture but also lighter and therefore cheaper.
  • the hub body Due to the geometrical shape of the paddle wheel body (S-shape), the hub body, which is designed as a disc with a central through-hole, can be easily connected on the one hand to the tapering area of the hub support and on the other hand to the frustoconical area of the support body. Additional support elements, such as those used in the St. d. T. are necessary, can be omitted here.
  • the paddle wheel body can be produced by both cold and hot forming.
  • the choice of the deformation process depends on the size and performance of the opencast mining device.
  • the St. d. T. mentioned manufacturing processes (rolling) only the frustoconical contour of the support body can be produced.
  • the radii required for the further machining can be formed without any problems, so that the welding work previously required at these points can be completely eliminated.
  • the further construction of the paddle wheel body can be carried out in modular form by directly welding the carrier for receiving the blades into the free space of the ring carrier or by connecting a circumferential flange to the ring carrier, to which the carrier is then screwed.
  • a peripheral disk or a U-profile open to the outside can also be screwed or welded onto the free end of the carrier.
  • the bucket wheel body 1 shows a schematic representation of the structure of the bucket wheel body 1 according to the invention.
  • the bucket wheel body 1 is constructed from the following elements: a frustoconical support body 2, a ring carrier 3 adjoining in the radially outer circumferential region and a hub support 4 molded in the radially inner circumferential region.
  • Ring carrier 3 and hub support 4 are S-shaped in cross-section, this profile being produced by deep-drawing a sheet.
  • a horizontally extending stiffener 6 is incorporated.
  • a circumferential flange 9 is welded on, which serves for the displacement (screwing) of the carrier 10 for receiving the blades (not shown).
  • U-shaped elements 21 with a cross-section are screwed onto the free ends 11 of the support 10 as a circumferential component.
  • a rounding is also provided, which forms the so-called hub support 4.
  • the hub 12 itself is designed as a disk with a central through bore 13.
  • Hub 12 and hub support 4 are connected to one another in such a way that the free end 14 of the hub support 4 is supported above the through bore 13 on the hub 12 and the radially outer peripheral region 15 of the hub 12 is supported on the frustoconical support body 2, the respective contact parts being welded to one another will.
  • FIG. 2 shows a tell-tale view of the impeller body 1.
  • the area of the hub support 4 and the hub 12 is shown.
  • the hub 12 is seated on the drive shaft 16, which has a radial stop 17 and is connected to the hub 12 by screwing 18.
  • Hub 12 and hub support 4 are connected to one another in the region of their contact points 19, 20 by welding.
