Definitions

  • the invention relates to a compressor unit according to the preamble of claim 1.
  • Such a compressor unit is known from EP-A-0 383 238.
  • the motor is connected to the housing of the muffler, which serves as a foot part for the installation of the complete unit.
  • the side channel compressor housing is flanged to the motor housing.
  • the side channel compressor housing is centered by the connection flange of the motor.
  • the invention has for its object to develop a compressor unit of the generic type ⁇ o that despite the misalignment caused by manufacturing tolerances, the parts can be connected to each other without further alignment.
  • the problem is solved by the features specified in the characterizing part of claim 1.
  • the elastic intermediate member on the one hand compensates for misalignments between the inlet and outlet of the side channel compressor and the connection openings of the muffler and, on the other hand, keeps loading forces away from the compressor housing.
  • a bellows can advantageously be provided as the elastic intermediate member.
  • a structurally simple possibility of connecting the drive motor and the muffler is that the support feet of the drive motor are connected to the muffler housing with screws which are inserted with their polygonal screw head into corresponding polygonal recesses provided on the inside of the muffler housing wall in question.
  • the screws are secured against twisting, so that no counter-holding is required when screwing the grub nuts onto the screw thread of these screws.
  • the screws can be attached to the muffler wall in question before the muffler parts are installed in the muffler housing and then held in place by the muffler parts inserted into the muffler housing. This means that the silencer can be completely assembled before it is attached to the drive motor and then connected as a finished component to the feet of the drive motor.
  • a tight connection between the halves forming the muffler housing is achieved in that, with these halves, at least the housing edges which extend transversely to the longitudinal axis of the muffler relative to the parting plane of the
  • Muffler housing are convex
  • a drive motor provided with a connecting flange 2 is designated by 1.
  • the centering of the side channel compressor 3 with respect to the drive motor 1 is achieved by means of a centering edge 7 formed on the connecting flange 2 and overlapped by a centering ring 8 cast onto the housing halves 4 and 5.
  • the impeller 9 of the side channel compressor 3 is twisted with its hub part 10 connected to the free end of the shaft 11 of the drive motor 1.
  • a muffler 12 is arranged below the drive motor 1.
  • the drive motor 1 rests with its set-up feet 13 on the silencer housing 14 consisting of two halves 14a and 14b.
  • the muffler housing 14 is firmly connected to the mounting feet 13 of the drive motor 1 by means of screws 15.
  • the screws 15 are inserted through openings provided in the corresponding wall of the muffler housing 14 in such a way that their threaded part 16 projects outwards. With their hexagon head 17, the screws 15 are inserted into hexagonal recesses 18, which are provided on wall projections 19 of the silencer housing 14. Since the muffler housing 14 consists of two halves 14a and 14b, the screws 15 can be attached to the corresponding wall of the muffler housing 14 before these halves 14a and 14b are assembled. Due to the damping parts also to be inserted into the muffler housing 14, for example a wire mesh sleeve 20 and a surrounding layer of foam 21 or the like, the screws 15 are so supported that their hexagon head 17 m remains in the respective recess 18.
  • the halves 14a and 14b of the muffler housing 14 can be firmly connected to one another after the parts have been introduced, so that the muffler 12 is available as a finished unit for assembly on the mounting feet 13 of the drive motor 1.
  • the screws 15 of the muffler 12 are inserted through fastening holes 22 in the support feet 13.
  • the muffler housing 14 is then connected to the support feet 13. Since the hexagonal heads 17 are secured against rotation in the hexagonal recesses 18, screwing on the threaded nuts 23 presents no difficulties.
  • protruding mounting feet 24 are integrally formed, with which the muffler housing 14 can be fastened to a floor surface at the installation site of the compressor unit by means of appropriate fastening means.
  • the muffler housing 14 thus forms the base part for the compressor unit.
  • the flow connection between the inlet and outlet openings 25 and 26 of the side channel compressor 3 and the connection openings 27 of the muffler 12 takes place by means of a bellows 29 which is slipped over the connection ports 28 of these openings 25-27.
  • a bellows 29 are used to misalignment bridges the openings 25 and 27 or 26 and 27 to be interconnected.

Abstract

L'invention concerne un système compresseur qui comprend un compresseur de canal latéral (3) et un moteur d'entraînement (1) relié à ce dernier, ainsi qu'un amortisseur de bruit (12) associé à l'entrée (26) et à la sortie (27) du compresseur de canal latéral (3). L'alignement mutuel du moteur d'entraînement et du compresseur de canal latéral peut être obtenu sans élément constitutif de structure spéciale, dans la mesure où le moteur d'entraînement (1) sert d'élément de jonction central entre le compresseur de canal latéral (3) et l'amortisseur de bruit (12). Ce dernier (12) est raccordé par ses ouvertures de raccordement (28) à l'entrée (26) et à la sortie (27) du compresseur de canal latéral (3), par un élément intermédiaire élastique (29).
