Definitions

  • the invention relates to a compressor unit according to the preamble of claim 1.
  • Such a compressor unit is known from DE-U-77 15 000.
  • the four housing halves required for the two side channel blowers are all designed differently. This leads to high manufacturing costs.
  • the connection of the individual housing parts takes place by interposing the middle housing parts between the outer housing parts, which are connected to one another by means of tie rods which engage on connecting lugs provided on the outer housing parts. The entire force must therefore be absorbed by the connecting straps of the outer housing parts.
  • a compressor unit known from FR-A-2 294 114 which consists of a total of four side channel compressors, which are held together by tie rods acting on the outer housing parts of the entire unit.
  • the housing halves located in the middle of the assembly are of identical design in terms of casting technology. Connecting straps are provided on these housing halves, which correspond to corresponding connecting straps provided on the outer housing halves. By means of these connecting straps, the two housing parts, each belonging to a side channel compressor, can be connected to one another. None is said in this document about the possibility of connecting the two side channel compressors to one unit.
  • the invention has for its object to provide a compressor unit that is easier to manufacture and in which the forces necessary for connecting the housing halves are better distributed.
  • the problem is solved by the features specified in the characterizing part of claim 1. Due to the same design in terms of casting technology, at least the inner housing halves, the outlay for the die casting tools required for producing the housing halves is reduced. Due to the special design of the connecting straps, good transmission of the forces in the axial direction is achieved without having to accept harmful bending moments. In addition, the two inner housing halves can be assembled into an assembly in advance.
  • a connection of the housing halves that is completely free of bending moments can be achieved by assigning two connecting lugs on one end face of the respective housing half to a connecting lug symmetrically aligned with these connecting lugs and lying on the other end face of the housing half.
  • the transmission of the forces over the full axial length of the unit without damaging bending moments is achieved according to one embodiment of the invention in that the connecting tabs of the center housing halves are provided with corresponding connecting tabs on the outer housing halves.
  • the two connecting straps with their mutually facing sides are aligned approximately in alignment with the outer sides of the one connecting strap.
  • the actual housing can be relieved of the connecting forces in that the connecting lugs arranged on the two end faces of the housing halves are connected to one another by axially extending webs, the webs on the two connecting lugs in the region of their mutually facing sides and engage one connecting lug in the area of the outer sides thereof.
  • 1 designates the outer housing half of a side channel compressor 2 of the compressor unit, which lies on the side facing away from the drive side of the compressor unit and is provided with a bearing bore 3 for an end bearing 4 of the drive shaft 5 of the unit.
  • the inner housing halves 8 and 9 of the two side channel compressors 2 and 7 are arranged.
  • the outer housing half 6 of the other side channel compressor 7 and the two inner housing halves 8 and 9 are of identical design in terms of casting technology. These housing halves 6, 8 and 9 must therefore only be machined accordingly with regard to the necessary bores and centering edges.
  • connecting straps 10 and 10a are provided on their outer circumference. These have corresponding through bores 11 and threaded holes 12 into which screws 13 can be introduced as connecting elements.
  • two connecting tabs 10 are arranged on the one end face 14 of each housing half 1, 6, 8 and 9 with a circumferential distance from one another.
  • the individual connecting straps 10a lying one before the other are each connected to one another by means of a single screw 13. With the two spaced-apart connecting straps 10, one or two connecting straps 10 can be screwed together. A screw connection on both connecting straps 10 leads to a complete symmetry with regard to the connecting forces that occur overall.
  • the individual connecting lugs 10a are connected by means of a screw 13 which extends continuously over the inner housing halves 8 and 9.
  • the two connecting straps 10 on one end face 14 are each connected via axially extending webs 16 to the individual connecting strap 10 a located on the other end face 15.
  • the webs 16 extend from the mutually facing sides of the two connecting straps 10 to the outer sides of the individual connecting straps 10a. This leaves a space circumferentially between the webs 16 through which the screws 13 can be passed.
  • FIG. 4 shows a further connection variant.
  • the two circumferentially spaced connecting tabs 10 are combined to form a continuous, widened connecting tab 17 on one end face 14.
  • two circumferentially spaced support webs 18 each extend in the axial direction to other end faces 15 of the housing halves 1, 6, 8 or 9.
  • the inner housing halves 8 and 9 are connected to one another by screws introduced into the widened connecting straps 17.
  • connection of the outer housing halves 1 and 6 to one another and to the inner housing halves 8 and 9 takes place by means of continuous tie rods 19 which are arranged in the middle of the widened connecting lugs 17 and which engage the widened connecting lugs 17 of the outer housing halves 1 and 6.

Abstract

l'invention concerne un groupe compresseur constitué d'au moins deux compresseurs à canal latéral (2, 7) juxtaposés dans le sens axial, qui présentent chacun un carter constitué d'au moins deux moitiés de carter (8, 9) comportant à leur extrémité extérieure des colliers de liaison (10, 10a) dépassant à l'extérieur dans le sens radial et qui sont reliés entre eux par des éléments de liaison (13) entrant dans des orifices (11, 12) des colliers de liaison (10, 10a). La fabrication de ce groupe compresseur et la répartition des forces de liaison sont améliorées par le fait qu'au moins les deux moitiés de carter (8, 9) placées au centre du groupe compresseur sont réalisées par la même technique de fonderie et que les colliers de liaison (10, 10a) prévus pour ces moitiés de carter sont constitués de telle manière qu'il subsiste, des deux côtés d'un élément de liaison (13) inséré au centre des colliers de liaison (10, 10a), un espace suffisant pour l'introduction d'un deuxième élément de liaison (13).

Claims (5)
