Definitions

  • the present invention relates to a variable geometry baffle, in particular for a turbine housing with central outlet, with one around a central outlet Axis arranged around wreath of vanes, which in turn each around a Swivel axis are pivotable around a blade bearing ring for storing the Blades around the central axis and an adjusting ring relative to the blade bearing ring is pivotable about the central axis and with the blades for adjusting whose angular position is connected in each case about their pivot axes.
  • Compounds of this The latter type have become known in a variety of ways and can from Radially mounted around the central axis of pivoting shafts for the blades Be formed levers, of interlocking tooth segments or slotted cam, which pins on the vanes lead.
  • the present invention is not applicable to any limited to these compounds.
  • the present invention also relates to a turbocharger with an inventive Leitgitter and with at least one turbine housing and an this releasably attachable bearing housing.
  • Guiding gratings of this type are known from numerous publications, such as US-A-4,179,247 or US-A-5,146,752 known. Especially the latter shows how awkward the individual Parts of the Leitgitters are to be mounted on the housing, because different parts into each other plugged, fitted and connected together, especially during installation in a turbocharger - or at least in a turbine unit.
  • the invention is based on the object, the installation costs by a simple and reduce compact structure and a guide grid of the type mentioned to assemble easily and quickly.
  • This object is achieved in two stages in that the blade bearing ring opposite a central opening having a disc with a such axial distance, with respect to the central axis, is arranged that between them and the vane ring of the ring of vanes is located, and that At the central opening at least one driver attacks, which at one in the central Outlet nozzle of the turbine housing insertable sleeve is mounted so that the sleeve for the axial fixing of the guide grid in a turbine housing together with the Leitgitter in its central outlet can be inserted and fastened.
  • the guide grid as a module (or "Cassette"), which, of course, because of the smaller dimensions (in comparison with an installation directly into the turbine housing) can be done easier and faster.
  • the assembly can by frictional retention of the sleeve in the center Opening done. But once you have the disc provided, then the created Module (the "cassette") in a preferred manner in the turbine housing so attached be provided by providing the sleeve with at least one driver.
  • This at least a driver is preferably of a radially extending and the Be formed disc-engaging flange.
  • the invention also relates to a turbocharger with such a guide grid, the at least one turbine housing and a releasably attachable to this bearing housing having.
  • This turbocharger is inventively characterized in that on a bearing housing facing, surrounding the opening of the outlet Wall of the turbine housing at least one connector for radial fixing the Leitgitters is provided, whereas the axial fixing by a sleeve in Outlet retaining device takes place. In this way, an exact attachment be achieved in the shortest possible time and with minimal effort.
  • a part of a turbine housing 2 of a turbocharger 1 is shown, which typically winds around a central axis R about spirally Supply channel 9 for a fluid - in the case of a turbocharger of the exhaust gas of an internal combustion engine - having.
  • This fluid is then in the radial direction by a, in itself known, arranged around the central axis R ring of vanes 7 a located on the axis R, turbine rotor, not shown, fed to the end of a (Also not shown) shaft sitting in a bearing housing 40, in stored therein bearings 41 and 41 'is mounted.
  • a turbocharger extends this shaft through this bearing housing 40 through to one at the other end attached compressor housing, the compressor rotor of the shaft - and thus of the turbine housing 2 supplied exhaust gases is driven in a known manner.
  • FIG. 2 illustrates these relationships, wherein a rolling bearing with rolling elements 3 in the form of rollers between an adjusting ring. 5 and a blade bearing ring 6, in which the pivot axes of the vanes 7 forming Adjusting shafts 8 are stored.
  • the rotation or adjustment of the adjusting 8 and the actuating ring 5 which actuates it can be known per se and, for example, in the US Pat US-A-4,659,295 nachzulesender done manner. In any case, it causes it known control that the adjusting ring 5 relative to the fixed blade bearing ring twisted, which results in a corresponding pivoting of the shafts 8.
  • grooves or recesses 17 of the adjusting ring 5 are the free ends of the lever or heads 18 are mounted by adjusting levers 19 which are fixed to the adjusting shafts 8.
  • adjusting levers 19 are fixed to the adjusting shafts 8.
  • grooves are provided on the radially inner side of the adjusting ring 5 are in which the heads 18 are mounted, so that then these heads 18 a certain Secure pre-centering. It is clear that this is just one possible implementation, and It was already mentioned at the outset that the adjustment also via slotted cam or interlocking gears are going on and being transmitted could.
  • the adjusting ring 5 has a radially inwardly directed running surface 20, on which the rollers. 3 can expire. However, this is preferably provided only for tolerance compensation, because in In practice, it is preferred if the rollers 3 in substantially all operating conditions both opposite this tread 20 and an opposite outer one Shoulder forming tread 21 on the vane bearing ring 6 have a certain play.
  • rollers 3 are required if these are provided with a cage or retaining ring 22 is assigned.
  • the rollers 3 in recesses of this Retaining ring 22 could run, the rollers 3 advantageously have axial extensions 24th smaller diameter, which engage in holes 25 of the retaining ring 22, so that this on the one hand ensures their distance in the circumferential direction and on the other hand, the rollers and axially firmly on their track against the treads 20 and 21 holds.
  • a sealing ring 27 is inserted into a sealing groove 28 of the blade bearing ring 6.
  • the blade bearing ring 6 is located in the region of a housing wall portion 2a.
  • Now different sealing arrangements are conceivable: Either the sealing ring 27 is formed as a flexible sealing lip, which is against the Wall 2a lays. This is not a problem in itself, because these two parts in operation yes do not move relative to each other. But it can also (possibly additionally) the (or a) Sealing ring 27 protrude into a groove of the wall 2a and thus form a kind of labyrinth seal, indeed combinations of both possibilities are possible as well as in the field the seals known solutions can be applied. Clearly with this seal in any case, soiling from the area of the feed channel 9 of the rolling bearing 3, 20, 21 kept away.
  • the blades 7 protective mounting ring or a disc 29 is provided which on the rotor housing 2 approximately in the areas of Fig. 1 apparent housing flange 2b is attached.
  • the fastening ring 29 is indicated by dashed lines, e.g. inserted through the sleeves 31 pin 30 'on Shovel ring 6 is fixed, in a known manner, the spacers 31 for a Provide slightly greater distance than the width of the blades 7 corresponds to this at their movement in all temperature ranges not to hinder. This way you can Thus, the apparent from Fig. 2 Leitgitter be pre-assembled to enter the turbine housing 2 to be used.
  • the sleeve 45 has at least one Driver 46, the disc 29 - and thus the whole Leitgitter module - when inserting entrains in the outlet port 10 and thus determines the axial position of the module.
  • driver 46 it should be understood be that it would be possible over the circumference of the sleeve 45 a plurality of radially projecting Claws or projections, in particular at regular angular intervals to provide.
  • the driver as extending radially from the sleeve 45 extending, the disc 29 engaging behind flange 46th is trained.
  • the disc 29 at the central opening has at least one recess 47, in which the at least a driver 46 engages so that it is preferably flush with the surface of the disc 29 concludes.
  • a plurality of circumferentially distributed radial projections could also be provided over the circumference distributed recesses be. This would at the same time a precise definition of the Leitgitter module in the direction of rotation take place around the central axis R.
  • the recess 47 as in the circumferential direction of the sleeve 45 extending groove (see Fig. 2) is formed is.
  • the disc 29 For fixing in the circumferential direction is preferably at least one bore 48th (Fig. 2) and / or 48 '(Fig. 1) provided in the disc 29, the one in the turbine housing 2, in the wall 2b, sitting pin 49 receives. It was already on top noted that the determination in the circumferential direction by the recesses (at least one) could be done. According to another alternative, the arrangement could be reversed, so that the disc 29, for example, carries a molded pin, the is inserted into a hole of the wall 2b. Furthermore, the determination could be in the circumferential direction also done with the help of bolts, but this is because of the extra Assembly costs not preferred.
  • the turbine housing 2 is processed such that the insertion of the sleeve 45 by screwing by means of a thread 50 takes place. Therefore must be cut into the axial neck 10, an internal thread into which a corresponding External thread of the sleeve 45 can be screwed. In itself, the axial fixing then secured when the disc 29 abuts against the wall 2b. However, vibrations can during operation cause the thread to loosen. Therefore, to Securing the sleeve 45 welded or plastically deformed.
