Definitions

  • the invention relates to a side channel compressor, comprising a compressor housing consisting of two housing halves, in which an impeller provided with conveyor blades is rotatably arranged and its hub part is connected to a drive shaft of a drive motor which projects into the housing through an insertion opening provided on one housing half.
  • Such a side channel compressor is known from DE-U-87 04 066.
  • the housing and the impeller of such compressors are usually made of cast aluminum parts. If you want to manufacture the compressor housing from a different material, then the structural design of the known side channel compressor cannot readily be adopted because of the different properties of the other material compared to aluminum.
  • the invention has for its object to find an embodiment for a side channel compressor, the housing of which can be produced from a material other than metallic.
  • the object is achieved according to the invention in that when the compressor housing is made of plastic, the gaps existing between the impeller and the compressor housing are sealed by means of corresponding sealing elements and the circumferential edge of the insertion opening surrounds the drive shaft with radial play.
  • the radial play between the peripheral edge of the insertion opening and the drive shaft enables radial alignment of the housing halves with respect to the impeller arranged on the drive shaft due to the low dimensional accuracy of the plastic material. So that the housing halves can be without any Leave post-processing in its production state and be assembled into a compressor housing in this state.
  • a good seal of the gaps can be achieved in that the conveying blades are arranged on a support ring connected to the hub part, which axially projects beyond the hub part on at least one side and the sealing elements are arranged in the region of the support ring. Sealing elements extending in the axial direction and mountable in the axial direction can then be used. These can consist, for example, of a flat strip which can be inserted into a corresponding annular groove in the respective housing half.
  • a centering ring which is close to a centering edge provided on the connecting flange of the drive motor is provided on the housing half having the insertion opening.
  • Such a close abutment of the centering edge and the centering ring creates a sealing space delimited by the wall area of the relevant housing half located within the centering ring and the wall area of the connecting flange located within the centering edge. This means that no sealing of the insertion opening provided for the insertion of the drive shaft into the relevant housing half with radial play relative to the drive shaft is required.
  • the housing of a side channel compressor consisting of two housing halves 2 and 3 is designated.
  • An impeller 4 is rotatably arranged in the compressor housing 1, the conveying blades 5 of which are arranged on a support ring 7 connected to a hub part 6.
  • the hub part 6 is non-rotatably seated on the free end of the shaft acting as the drive shaft 8 of a drive motor 9 flanged to one housing half 2.
  • the drive shaft 8 projects into the compressor housing 1 through an insertion opening 11 formed on a hub projection 10 of the one housing half 2.
  • the peripheral edge 12 of the insertion opening 11 surrounds the drive shaft 8 with radial play.
  • An axially protruding centering ring 13 is also formed on one housing half 2 and engages over a centering edge 15 provided on the connecting flange 14 of the drive motor 9.
  • a sealing means can be provided between the overlapping surface of the centering ring 13 and the centering edge 15, so that the space 21 located within the centering ring 13 and the centering edge 15 acts as a sealing space with respect to the insertion opening 11.
  • the delivery chamber of the side channel compressor formed by side channels 20 is sealed to the outside by sealing rings 19 arranged in the area of the support ring 7 on the housing halves 2 and 3. Thus, in the area of the insertion opening 11, no precautions are required to seal this opening.
