Definitions

  • the invention relates to a pump or compressor with at least one in a working housing revolving on the drive side flying bearing impeller, to the exact axial Positioning the impeller on a drive shaft Fastening device has.
  • DE-AS 10 64 813 or FR-A-1015756 describes an attachment of the first Loose impellers built into the housing of a centrifugal pump, which in their final position on the pump shaft through Body by means of an arranged on the shaft axial Actuator in the radial direction against the inner surface of the Wing hubs are pressed in place. There is the serving as Verspannglied body of a feather whose within the wheel hub lying part are deformable.
  • the invention is therefore the object of a fastening device for impellers of pumps or compressors to create that with simple means is.
  • An axial positioning of the impeller on the drive shaft is achieved by a screw with preferably cone-shaped screw head in the thread of the drive shaft is screwed in. This spreads the slotted disc due to its conical recess and the radial Slot within the cylindrical recess of the impeller, so that the disc as preferably radially acting Clamping element acts.
  • the opening in the middle of the Washer for holding the screw is designed that ever after using a certain screw the associated Screwing the washer when screwing into the thread of Stub shaft pushes the disc apart and so a radial Tensioning of the disc on the inside of the impeller causes.
  • the disc has at least two independent circle segments (for example Half discs), which, as already described above, also serve for gap adjustment and torque transmission.
  • the disc 1 shows a disc 1 with a centrally disposed opening 2 which serves to receive a screw 3.
  • the disc 1 has a cone-shaped 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 knows a predetermined width on.
  • the slot 6 serves that if the Screw 3 is inserted and tightened the conically shaped Screw head 6, the disc 1 presses apart.
  • the disc 1 thus acts as a radial clamping element.
  • To material stresses within the disc 1 is to prevent the addition radially non-continuous slot 7 is provided. The Material stresses can also be achieved by other similarly shaped Slots 7 realize.
  • the disc 1 can be made of metal or another deformable but approximately volume resistant Fabric exist.
  • FIG. 2 shows the impeller 8 of a not shown Liquid ring pump.
  • the impeller 8 via the invention Fastening device driven by a shaft 9.
  • the shaft 9 has in its stub shaft 10 a thread 11 on, in which the screw 3 during assembly of the impeller 8 is used.
