Definitions
- the invention relates to a blade bearing ring arrangement for a turbocharger with variable turbine geometry (VTG) according to the preamble of claim 1.
- VFG variable turbine geometry
- the VTG cartridge of such from the EP 1 236 866 A known turbocharger consists of a nozzle with blades and levers and turbine housing side disc. The attachment of the disc to a vane bearing ring of a vane bearing assembly takes place in generic turbochargers by means of screws or welding. To be able to set a defined width for the flow channel, which forms between the blade bearing ring and disc and in which the blades of the VTG are located, spacer sleeves are required, which can be removed in the case of a welded joint after welding again. By welding, however, a distortion of the disc caused by strong heat input. A distortion of the disc can lead to a clamping of the blades due to the consequent local gap reduction between blades and disc.
- the solution of this object is achieved by the features of claim 1.
- a heat choke is provided which surrounds the recess for the support pin end to be welded.
- This heat choke is designed as a circumferential groove around the recess for the support pin end to be welded.
- the first end of the support pins can be screwed, riveted or otherwise fixed to the disc.
- the support pins preferably have a very small diameter of a few millimeters, so that the resulting flow cross-section reduction and the associated Strömungsverwirbelonne remain minimal.
- FIG. 2 only one vane bearing assembly 1 of a turbocharger according to the invention shown.
- the blade bearing arrangement 1 has a blade bearing ring 2, on which a disc 3 is arranged at a defined distance.
- the disc 3 is preferably formed of the same material as the blade bearing ring 2 and serves, as stated, to set an exact axial gap in order to define a flow channel 4 can.
- a support pin 5 For attachment of the disc 3 on the blade bearing ring 2 is at least one, but usually provided a plurality of support pins, of which in Fig. 2 a support pin 5 is visible.
- the support pin 5 has a first and a second end 6 and 7, respectively. Between the ends 6 and 7, a shaft region 8 arranged in the flow channel 4 is arranged in the assembled state.
- the second end 7 of the support pin 5 is disposed in a recess 11 of the disc 3 and connected in a flared area 12 of the recess 11 with the disc 3 via a weld 13.
- the end 7 is roof-like tapered at its end face in order to achieve a perfecting of the weld 13 can.
- a heat choke in the form of a circumferential groove 14 is provided, which prevents the heat can penetrate directly into the massive part of the disc 3, which helps to avoid distortion of the disc 3 during welding and also reduces the required input welding energy.
- the disc 3 is provided with one recess 11 per support pin 5, wherein each of these recesses 11 the above-described heat choke in the form of the circumferential groove 14 is attached.
- the first end 6 of the support pin 5 is screwed to the blade bearing ring 2 for fixing the disc 3 on the blade bearing ring 2.
- spacers between the blade bearing ring 2 and disc 3 are inserted to the defined distance to be able to adjust between the blade bearing ring 2 and the disc 3.
- the welding of the second end 7 and the removal of the spacers takes place.
