Definitions

  • the invention relates to a pump or compressor with at least one encircling a working housing on the drive side cantilevered impeller for precise axial Positioning the impeller on a drive shaft Fastening device has.
  • DE-AS 10 64 813 describes an attachment of the first Impellers of a centrifugal pump loosely built into the housing, in their final position on the pump shaft Body by means of an axial arranged on the shaft Actuator in the radial direction against the inner surface of the Wing hubs are pressed attached. There is the as a tensioning body from a feather key part lying within the wheel hubs are deformable.
  • the disadvantage here is that the fastening device presented relatively complex to assemble or manufacture is.
  • the invention is therefore based on the object of a fastening device for impellers of pumps or compressors to create that to realize with simple means is.
  • Axial positioning of the impeller on the drive shaft is achieved in that a screw with preferably conical screw head in the thread of the drive shaft is turned.
  • the slotted disc spreads due to their conical recess and the radial Slot within the cylindrical recess of the impeller, so that the disc acts as a preferably radial Clamping element works.
  • the slotted Disc in connection with a correspondingly shaped Screw both the gap between the impeller and the working housing, as well as a torque transmission from the drive shaft reached on the impeller.
  • the slotted disc shows advantageously a radially continuous slot from the Opening in the middle of the pane up to its outer edge on. To spread material tensions within the disc Reducing condition is at least one more radial slot provided extending from the central opening the disc extends outwards. This is another one Radial not continuous slot. More advantageous This additional slot is located opposite the radially continuous slot.
  • the opening in the middle of the Washer for receiving the screw is designed so that after inserting a certain screw the corresponding one Screw the disc when screwing into the thread of the Butt wave pushes the disc apart and so a radial Bracing the disc on the inside of the impeller causes.
  • the disc at least has two independent circle segments (e.g. Half disks), which, as already described above, serve for gap adjustment and for torque transmission.
  • two independent circle segments e.g. Half disks
  • the disc 1 shows a disc 1 with a centrally arranged opening 2 which serves to receive a screw 3.
  • the disc 1 has a conical recess 4 for receiving the Screw head 5 of the screw 3 is used.
  • Starting from the Opening 2 of the disc 1 runs a radial slot 6 to Outside.
  • the radial slot 6 has a predetermined width on.
  • Opposite is on the other side of the opening 2 a radial slot 7 is arranged, which only partially Extends outside.
  • the slot 6 serves that if the Screw 3 is inserted and tightened the conically shaped Screw head 6 pushes the disc 1 apart.
  • the disc 1 thus acts as a radial clamping element.
  • To material tensions To prevent within the disc 1 is the additional radially non-continuous slot 7 is provided. The Material tensions can also be reduced by other similarly shaped ones Realize slots 7.
  • the disc 1 can be made of metal or another deformable but almost volume-stable Fabric.
  • FIG. 2 shows the impeller 8 of a not shown Liquid ring pump.
  • the impeller 8 is over the invention Fastening device driven by a shaft 9.
  • the shaft 9 has a thread in its stub shaft 10 11 in which the screw 3 when mounting the impeller 8 is used.
