Definitions

  • the invention relates to an inner-axis rotary lobe machine with at least two inner rotors fastened to a common shaft and a corresponding number of outer rotors, which are enclosed by a common housing and are arranged axially next to one another, the engagement parts of the outer rotors in the circumferential direction with one another and in the axial direction with those of the adjacent one Outer rotor are rigidly connected by an annular, axially inner rotor disk, so that it surrounds the shaft of the inner rotor and axially divides the working spaces of the machine.
  • Machines of this type are known, for example, from FIGS. 22 and 27 of US Pat. No. 3,954,355. These machines are designed in such a way that their inner runners always laterally cover the space enclosed by the axially inner rotor disk, so that the axially adjacent working spaces are sealed off from one another. According to FIG. 27 of this US Pat. No. 3,954,355, the gear drive connection between an inner rotor pair and an outer rotor pair is arranged in this space enclosed by the rotor disk.
  • the invention has for its object to find a machine of the type mentioned that the stiffening connection between a plurality of external rotors, or. the axial subdivision of an outer rotor is also made possible for machines whose working spaces extend radially inward beyond the possible radially inner boundary of an outer rotor disk, so that the machine has an increased throughput volume.
  • the aforementioned radially inner boundary of an outer rotor disk is structurally due to the necessary radially offset arrangement of the shaft of the inner rotor relative to the axis of rotation of the outer rotor.
  • this object is achieved in that the space enclosed by the axially inner rotor disk is filled by a partition wall body, a bearing being provided between the rotor disk and the partition wall body and between this and the shaft, and working spaces of the machine up to the partition wall body reach up.
  • the partition body is not connected to any stationary part, and although it is only connected to rotating parts, i.e. In the radial direction, on the one hand, it borders on the rotor disk surrounding it and, on the other hand, on the shaft it encloses, it stands still itself. This results from the radial displacement of the axes of the two bearings mentioned.
  • the inner rotors 2, 3 and the outer rotors 4, 5 of the rotary piston machine shown rotate about axes 7, 8 which are fixed relative to the common machine housing 6, so that very high rotational speeds are possible.
  • the three engagement parts 4a, 4b, 4c of the outer rotor 4 could easily be produced from rod material with a relatively large axial length due to their constant cross-section in the axial direction. Due to bending loads caused by centrifugal forces, the free axial length of the engagement parts 4a, 4b, 4c is limited by an axially inner rotor disk 9, which rigidly connects these engagement parts 4a, 4b, 4c to one another in the circumferential direction.
  • the rigid connection is provided, for example, by a one-piece production of the engagement parts 4a, 4b, 4c with the rotor disk 9.
  • the axially adjacent outer and inner rotors 2 to 5 are preferably offset from one another in the circumferential direction by 180 °. The load peaks resulting from the compression in the machine consequently occur on both axially adjacent rotors 2, 3 and 4.5 not at the same time.
  • the size of the inner diameter of the axially inner rotor disk 9 is in the range due to the eccentricity of the shaft axis 7 of the inner rotor 2, 3, which is best seen in FIG of the rotor disk 9, wherein the required arrangement of a bearing 13 on the inner diameter 14 must also be taken into account, which keeps the frictional resistance between a partition wall body 15 enclosed by the rotor disk 9 and stationary relative to the machine housing 6 low.
  • This bearing 13 is therefore preferably designed as a roller bearing. In the illustrated embodiment, this bearing 13 is enclosed in circumferential grooves of the rotor disk 9 and the partition wall body 15, so that it is sealed against the working spaces 16 of the machine. It goes without saying that the bearing 13 or.
  • the roller bearing can also be provided in only one circumferential groove of the rotor disk 9 or the partition wall body 15.
  • the axial sealing of the annular gap between the rotor disk 9 and the partition wall body can be carried out by its narrow dimensions or by sealing rings 17, 18 engaging in a groove.
  • the working spaces 16 of a rotary piston machine extend radially inward substantially beyond the inner diameter 14 of the axially inner rotor disk 9 and become therein Extent area 19 limited in the axial direction by the partition wall body 15, which extends in the same plane as the rotor disk 9 and thus forms the radially inner continuation of the side surfaces 9a, 9b delimiting the working spaces 16.
  • the combination of the axially inner rotor disk 9 with the thus also axially inner partition wall body 15 results in an axial one Subdivision of the working spaces 16 of the machine, so that an axially separated area of the machine can be arranged as a high-pressure stage behind a first low-pressure stage.
  • FIG. 3 shows the flow channels 20, 21 between a low-pressure part 22 and a high-pressure part 23 of a rotary piston machine according to the invention, which are guided via an intercooler 24 around the gas heated by the compression in the low-pressure part 22 before it is further compressed in the high-pressure part 23 cool down.
  • the coolant circulates through the pipes 25, 26.
  • the outer rotor unit formed from the two outer rotors 4, 5 carries annular end bodies 30, 31 which are connected to the engaging parts 4a, 4b, 4c; 5a, 5b, 5c are screwed on, as indicated by lines 32, 33.
  • the outer rotor unit 4.5 is supported by means of roller bearings 34, 35, which are supported on filler bodies 38, 39 that are firmly connected to housing side plates 36, 37.
  • the gear-gear connection 10, 11 between the outer and inner rotor units 4, 5; 2, 3 in the speed ratio of 2: 3 is arranged between an outer and inner filler body 38, 40, which are screwed together.
  • the shaft 12 of the inner rotor unit 2, 3 is mounted in roller bearings 41, 42 which are held in the filler bodies 38, 39.
  • the bearing 43 between the axially inner partition wall body 15 and the shaft 12 is less stressed, since the bearing forces occurring there merely cause the separation to rotate to prevent wall body 15 with the axially inner rotor 9.
  • This bearing can accordingly be formed by a thin bearing shell 43.
  • the machine's inlet and outlet ports 44, 45 are located on the circumference of the housing 6.
