Definitions

  • the invention relates to a compressor unit according to the preamble of claim 1.
  • Such a compressor unit is known from DE-U-92 15 231.
  • a centering edge is provided on the individual housing halves radially outside the housing region forming the side channel.
  • the side channel blowers are centered on one another by the inner halves of the housing, which interlock with their centering edges.
  • the connection of the housing halves each belonging to a side channel compressor takes place via connection lugs provided on the outer circumference of these housing halves, into which connection screws are inserted.
  • the connecting straps adjoin the inner parting plane of the two housing halves.
  • connecting straps are provided on the outer circumference of the mutually facing housing halves of these side channel compressors, adjacent to the outer parting plane of these housing halves, into which connecting screws are likewise introduced.
  • the invention is based on the object of redesigning a compressor unit of the generic type such that both side channel compressors with the same housing diameters and with different housing diameters can be combined to form a compressor unit.
  • a casting engineering identical design of all housing halves of side channel compressors which can be assembled into a compressor unit is made possible in that in all housing halves the axial extension lies on the same radius as the axial extension necessary for coupling the respective outer housing half to the housing of the drive motor of the compressor unit.
  • their housing halves can have the same basic structure.
  • the bearing receptacle required for one outer housing half can be achieved in the casting mold by means of a corresponding, interchangeable mold insert.
  • each side channel compressor 1 or 2 denotes a first side channel compressor and 2 denotes a second side channel compressor.
  • the housing of each side channel compressor 1 or 2 consists of an outer housing half 3 and an inner housing half 4.
  • the housing halves 3 and 4 each enclose the impeller 5 of the side channel compressor 1 or 2 in the assembled state.
  • An axial shoulder 11 is formed on each housing half 3 and 4, respectively, on the axial hub shoulder 7 which surrounds the drive shaft 6 of the impellers 5 and the bulge 9 forming the respective side channel 8.
  • the axial lugs 11 of the two inner housing halves 4 serve to connect these two housing halves 4. Therefore, the axial lug 11 of the one housing half 4 is provided with through bores 12 and the axial lug 11 of the other housing half 4 is provided with threaded bores 13.
  • the two inner housing halves 3 can thus be connected to one another by means of screws 14.
  • the axial extension 11 can be designed as a circumferential ring or can also consist of individual projections.
  • the axial extension 11 provided on the outer housing half 3 facing the drive motor 15 of the first side-channel compressor 1 is used to fasten the compressor unit to the housing of the drive motor 15 of the first side channel compressor 1 can be fastened to the motor housing by means of connecting screws 16.
  • a bearing receptacle 17 is provided, in which the drive shaft 6 is supported with its free end.
  • this housing half 3 also has an axial shoulder 11, which, however, has no further function here.
  • the connection of the outer housing half 3 of the second side channel compressor 2 takes place via clamping bolts 18 inserted in through openings 19 provided on the outer circumference of all housing halves 3 and 4.
  • the clamping bolts 18 extend axially over all housing halves 3 and 4 and thus provide an additional fastening element for all housing halves 3 and 4 4.
  • a support ring 20 is provided on the outside of the housing halves 3 and 4, radially adjacent to the clamping bolts 18 and the push-through openings 19. For reasons of equality, this support ring 20 is integrally formed on each housing half 3 or 4.
  • the support rings 20 are dimensioned with respect to their axial extent so that the support rings 20 provided on the two inner housing halves 4 abut one another in the connected state of the inner housing halves 2. It is therefore not possible to warp the housing of the two side channel compressors 1 and 2 when the clamping bolts 18 are attached.
  • the inner housing half 4 of the second side channel compressor 2 When the inner housing half 4 of the second side channel compressor 2 is attached to the inner housing half 4 of the first side channel compressor 1, these two housing halves 4 are aligned by means of a centering edge 21 provided on the axial shoulder 11 of one inner housing half 4, which fits into one on the axial shoulder 11 of the other inner one Housing half 4 trained centering shoulder 22 engages.
  • the outer housing half 3 of the first side channel compressor 1 is centered on the motor housing by means of a centering edge 21 provided on the axial shoulder 11 of this housing half 3, which engages in a corresponding centering shoulder 22 of the motor housing.
  • the axial lugs are located on all housing halves 3 and 4, regardless of whether they are used to connect the housing halves 4 to one another or to connect the compressor unit to the drive motor 15 serve on the same radius.
  • the bearing receptacle 17 in the one outer housing half 3 can be achieved by a corresponding, interchangeable mold insert which can be inserted into the casting mold.
