Definitions

  • the present invention relates to a housing for turbomachines, such as turbocharger, secondary air chargers or the like., With a first rotor space for receiving a turbine rotor, a bearing space for a turbine rotor shaft carrying at one end, and a second rotor space for receiving an am another shaft end to be fastened compressor rotor, wherein the two rotor chambers are each surrounded by supply or discharge channels for a gas.
  • housings are known from numerous documents, for example from CA-1,270,120 or US-A-2,860,827, 4,179,247 and 4,659,295, respectively.
  • the housing consists of several - generally at least three - housing parts.
  • the turbine rotor space, the storage space and the compressor rotor space each dedicated to a separate housing part, which parts then have to be screwed together or connected to each other in other ways.
  • the multi-part design of the housing had in general also a special reason, namely in order to complicate the heat transfer and make the choice of materials according to the requirements.
  • DE-OS 31 33 952 discloses a turbocharger with a multi-part inner housing and a one-piece outer housing.
  • WO 95/25878 recommends that a turbocharger housing be made in one piece but does not give any indication as to how a turbocharger can be assembled with such a housing.
  • GB 1 315 307 shows a two-part turbocharger housing.
  • the invention is based on the finding that the multi-part design is not required in all cases and that it would therefore be desirable to reduce the cost of manufacturing and assembly.
  • the housing surrounding the storage space is at least partially formed integrally with the housing surrounding at least one of the rotor chambers. Accordingly, for example, for each of the two rotors a housing surrounding its space in conjunction with at least one Part of the housing surrounding the storage space are poured, so that at the end only the two rotors housing parts must be joined together.
  • a particular advantage of the embodiment according to the invention is that preferably only one single high-quality part has to be manufactured instead of several thereof (with mutual tolerance adaptation).
  • the rotor chambers can each be covered with a simple flange, so that the assembly of the housing requires only the mounting of the two flanges and therefore less expensive.
  • a unitary housing 1 made of, for example, a cast material such as gray cast iron or a light metal casting surrounds a turbine rotor space 2 for a turbine rotor 2 'shown in FIG. 1 at one of its ends, a compressor rotor space 3 for a compressor rotor 3' to be accommodated therein End and in between a storage space 4 for one of the two rotors 2 ', 3' in a known manner to one end bearing shaft 5.
  • Each of the rotor chambers 2, 3 is an approximately annular or spirally surrounding channel, namely a supply channel 6 or assigned to a discharge channel 7, wherein a gaseous medium - that is, for example, in the case of a turbocharger exhaust, in the case of a secondary air charger air, in another case, perhaps a liquid - the supply channel 6 via a from Fig. 2 apparent, preferably molded nozzle 8 is supplied.
  • Air is the compressor room 3 via an axial stub 17 is supplied to a housing cover 18 to be fastened to the housing 1 according to the invention by means of screws 19 (see arrow a ') and discharged from the discharge channel 7 via a connecting piece 9.
  • the housing 1 of the invention can be closed at the other end of a housing cover 20 and to threaded holes 21 (only one is shown) has, which - similar to the screws 19 - 22 receive screws. Also, this housing cover will then limit the rotor space 2, similar to the housing cover 18, the rotor chamber 3 limited. In a similar manner, it has an axial connection 23, via which fluid is discharged, which is supplied to the rotor 6 'via the supply channel 6, in accordance with the indicated arrow a.
  • the housing 1 is relatively strong, but formed with easy to manufacture shapes. In the context of the invention, it may well be to constrict it stronger between the turbine rotor chamber 2 and the compressor rotor chamber 3 and at most to provide it with ribs for heat dissipation.
  • the invention is by no means limited thereto. It would, for example, be conceivable to produce the housing 1 from two parts which can be connected to one another in a detachable manner, as indicated by dash-dotted lines L. Of course, then again a tolerance problem may arise, which is why the fully one-piece training for all three rooms 2-4 is preferred. But you can control the tolerance problems better if then the two parts of the housing 1 mating mating surfaces, in particular conical mating surfaces 10, have, so that they are nested and then only need to be fastened together in a conventional manner.
  • Such a subdivision of the housing 1 can of course also be done in other ways, for example by one of the rotor chambers 2 or 3 is surrounded by a housing which also includes the entire storage space. Another modification could be that the rotor chambers 2, 3 and the supply and Abbigbowkanäle 6, 7 are each equal.
  • the storage space 4 can accommodate a conventional, possibly also divided sliding bearing, but it can also be used a rolling bearing.
  • a cylindrical space 16 is provided at the other end of the storage space 4 (left in Fig. 1), in which an axial fixation, such as a thrust bearing, can be accommodated.
  • an axial fixation such as a thrust bearing
  • the storage space 4 has the form of a socket. In this way, it is possible to insert the shaft together with preassembled bearing unit (or initially only the bearings alone) in the hollow bush formed by the storage space 4, where it abuts against the annular wall 15.
  • the annular wall 15 itself with its opening 14 for the passage of the shaft 5 may either itself be designed as a sliding bearing or receive such.
  • the bearing unit which preferably has approximately the same axial length as the storage space 4
  • the axial fixing in the space 16 can take place.
  • an axial fixation are provided, such as by introducing at least one annular groove 24 for accommodating such a fixation in the bush-like bore of the storage space 4. In this way, it may be possible to provide the arrangement for an axial fixation of the bearing between the two ends of the storage space 4.
