Definitions

  • the invention relates to a side channel compressor, with a Compressor housing consisting of two housing halves, in which an impeller provided with conveyor blades is rotatably arranged and with its hub part with one by one on one Half of the housing provided insertion opening protruding into the housing Drive shaft of a drive motor is connected.
  • Such a side channel blower is by DE-U-87 04 066 known.
  • the housing and the impeller of such compressors is usually made from cast aluminum parts. If you want the compressor housing from another Manufacture material, then the construction of the known side channel blower because of the aluminum different properties of the other material not be taken over easily.
  • From US-A-5 049 770 is a generic side channel compressor known.
  • the disadvantage is that a relative complex structure of the side channel compressor is present.
  • the invention has for its object an embodiment for a side channel blower to find its housing producible from a material other than metallic is.
  • the problem is solved according to the invention characterized in that when the compressor housing is formed Plastic between the impeller and the compressor housing existing gaps sealed using appropriate sealing elements and the peripheral edge of the insertion opening are the drive shaft surrounds with radial play. Due to the radial play between the circumferential edge of the insertion opening and the drive shaft is due to the low dimensional accuracy of art radial alignment of the housing halves due to the material with respect to the impeller arranged on the drive shaft allows. So that the housing halves can be without any Leave postprocessing in its production state and in this condition can be assembled into a compressor housing.
  • a good seal of the gaps can be achieved that the conveyor blades on one connected to the hub part Support ring are arranged, the hub part at least one side projects axially and the sealing elements in the area of the support ring are arranged. It can then become axial Direction extending and mountable in the axial direction Sealing elements are used. These can, for example from a flat, in a corresponding annular groove of the respective Insert half of the housing insertable strips.
  • the insertion opening having a housing half close to one on the connecting flange of the drive motor provided centering edge subsequent Centering ring is provided.
  • the centering edge and the centering ring becomes one of those located within the centering ring Wall area of the relevant housing half and the inside of the centering edge of the wall area of the connecting flange bounded sealing space created.
  • With 1 is the housing consisting of two housing halves 2 and 3 called a side channel blower.
  • an impeller 4 is rotatably arranged, the Conveyor blades 5 on one connected to a hub part 6 Support ring 7 are arranged.
  • the hub part 6 is non-rotatably on the free end of the shaft acting as drive shaft 8 a drive motor flanged onto one housing half 2 9.
  • the drive shaft 8 projects through a on a boss 10 of the one housing half 2 formed insertion opening 11 in the compressor housing 1.
  • the peripheral edge 12 of the Insertion opening 11 surrounds the drive shaft 8 with a radial one Game.
  • unprocessed plastic parts compared to unprocessed Metal parts must have a lower dimensional accuracy when assembling the unprocessed housing halves 2 and 3 and the impeller 4 to a side channel compressor a corresponding Alignment of these parts to each other.
  • the housing halves 2 and 3 must be correspondingly radial to be aligned with the peripheral edge 17 of the conveyor scoop. Due to the radial at the insertion opening 11 Game between the peripheral edge 12 and the drive shaft 8 such a radial alignment of the housing halves 2 and 3 enables.
  • the drive motor 9 of radial clearance for centering the side channel blower with respect to the connecting flange 14 possibly necessary radial displacement of the compressor housing guaranteed.
  • sealing rings 19 By in the region of the support ring 7 on the housing halves 2 and 3 arranged sealing rings 19 is through the side channels 20th formed delivery space of the side channel blower to the outside sealed off. Thus, in the area of the insertion opening 11 no precautions are required to seal this opening.
