Definitions

  • the present invention relates to a housing for turbomachines, such as Turbocharger, secondary air loader or the like, with a first rotor space for receiving a Turbine rotor, a storage space for a shaft supporting the turbine rotor on one their ends, and a second rotor space for receiving one at the other shaft end compressor rotor to be fastened, with the two rotor spaces each or discharge channels for a gas are surrounded.
  • turbomachines such as Turbocharger, secondary air loader or the like
  • housings are known from numerous documents, for example from the 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 are mostly each dedicated to a separate housing part, which parts then together screwed or otherwise connected to each other.
  • the multi-part design of the housing generally had a special one Reason, namely to complicate the heat transfer and the choice of material accordingly to be able to meet the requirements.
  • the invention is based on the knowledge that the multi-part design is not in all Cases is necessary and therefore it would be desirable to consider the cost of manufacture and lower assembly.
  • the housing surrounding the storage space at least in part with the housing surrounding at least one of the rotor spaces is formed in one piece. Accordingly, for example, for each of the two Rotors a housing surrounding its space in connection with at least one Part of the housing surrounding the storage space are cast, so that at the end only the two rotor housing parts need to be joined together.
  • a particular advantage of the configuration according to the invention is that it is preferred only one technically high-quality part made in place of several (with mutual tolerance adjustment) must be.
  • the rotor rooms can each with a simple flange are covered, so that the assembly of the housing only that Mounting the two flanges required and is therefore less expensive.
  • a uniform one for example made of a cast material, such as gray cast iron or cast from one Light metal, manufactured housing 1 surrounds a turbine rotor chamber 2 for one in Fig. 1 shown turbine rotor 2 'at one of its ends, a compressor rotor chamber 3 for a compressor rotor 3 'to be accommodated therein at the opposite end and in between a storage space 4 for one of the two rotors 2 ', 3' in a known manner Way at each end carrying shaft 5.
  • Each of the rotor spaces 2, 3 is approximate annular or spiral surrounding channel, namely a feed channel 6 or a Discharge channel 7 assigned, wherein a gaseous medium - so for example in the case a turbocharger exhaust, in the case of a secondary air charger air, in another case perhaps a liquid - the feed channel 6 via one shown in FIG. 2, preferably molded connector 8 is supplied.
  • Air is over the compressor room 3 an axial socket 17 on a housing 1 according to the invention by means of screws 19 to be fastened to the housing cover 18 (see arrow a ') and from the discharge duct 7 discharged through a nozzle 9.
  • housing 1 also at the other end of one Housing cover 20 can be closed and threaded holes 21 (only one is shown), which - similar to the screws 19 - receive screws 22.
  • This housing cover will then also limit the rotor space 2, similar to that Housing cover 18 limits the rotor space 3.
  • it has an axial one Spigot 23, via which - according to arrow a - fluid is discharged, which was fed to the rotor 6 'via the feed channel 6.
  • the housing 1 is relatively strong, but with simple Forms to be produced. In the context of the invention, however, it can be stronger between the turbine rotor space 2 and the compressor rotor space 3 constrict and if necessary also provide it with ribs for heat dissipation.
  • FIG. 1 Although a uniform housing surrounding all three rooms 2-4 can be seen from FIG. 1 is, the invention is in no way limited to this. It would be, for example conceivable to manufacture the housing 1 from two parts which can be detachably connected to one another, how dash-dotted is indicated with a line L. Of course, then again Tolerance problem arise, which is why the completely one-piece training for all three rooms 2-4 is preferred. But you can better master the tolerance problems, if then the two parts of the housing 1 interlocking mating surfaces, in particular conical Fit surfaces 10, so that they are nested and then only with each other must be attached in a manner known per se.
  • Such a division of the housing 1 can of course also be done in a different way, for example by one the rotor rooms 2 or 3 is surrounded by a housing that also covers the entire storage room includes. Another modification could be that the rotor spaces 2, 3 and the supply and discharge guide channels 6, 7 are each of the same size.
  • the storage space 4 can accommodate a conventional, if necessary also subdivided, slide bearing, however, a roller bearing can also be used.
  • a cylindrical Space 16 is provided, in which an axial fixation, for example an axial bearing, can be accommodated.
  • an axial fixation for example an axial bearing
  • Such axial fixations or axial bearings are known to the person skilled in the art known and therefore do not need to be discussed in detail here.
  • So has the storage space 4 is in the form of a socket.
  • the shaft including the pre-assembled bearing unit (or initially only the bearing alone) in the from Storage space 4 formed hollow socket to insert where it strikes the annular wall 15.
  • the ring wall 15 itself with its opening 14 for the passage of the shaft 5 (i.e. the opening 14 corresponds at least approximately to the diameter of the shaft 5) either be designed as a plain bearing or take one.
  • the Bearing unit which preferably has approximately the same axial length as the storage space 4 has been inserted into this space 4, then the axial fixation in space 16 respectively.
  • an axial fixation can be provided, for example by in the bush-like bore of the storage space 4 at least one annular groove 24 for Bring such fixation brings. In this way it may be possible the arrangement for an axial fixation of the bearing between the two Provide ends of the storage space 4.
