Definitions

  • the invention relates to an adjusting ring for adjusting the blades of the VTG diffuser of exhaust gas turbochargers, according to the preamble of claim 1.
  • VTG diffuser is understood to mean an arrangement which serves to provide exhaust gas turbochargers with a variable turbine geometry.
  • an adjusting ring specified in the preamble of claim 1, which has a bearing ring for receiving bearing bodies and a lever engagement ring.
  • the lever engagement ring is provided with grooves in which the levers of the VTG blades engage.
  • Such known adjusting rings for example, from the EP-A-1 398 463 are known, are constructed as fully machined components, which are usually produced in turning or milling operations or combined operations.
  • the adjusting ring is formed with its bearing ring and a lever engaging ring as a one-piece part of a solid material.
  • this represents a relatively time-consuming and costly production process.
  • the adjusting ring is made of several, at least two, separately manufactured individual parts, which are connected to one another by means of a suitable connecting device.
  • the individual parts can in this case by Urform- (investment casting or sintering), forming (pressing) or separation processes, preferably stamping, be made completely or require a small machining finishing, such as turning or milling.
  • the items may consist of different materials, which are adapted to the specific function of the bearing of the bearing ring or bearing portion of the adjusting and the leadership of the blade lever of the lever engagement ring or lever engagement portion.
  • bearing ring and the lever engagement ring can be adapted in terms of their geometry in a simple manner to the said functions. For example, a specific hardening of the surface according to the required properties is possible.
  • the bearing ring and the lever engagement ring are each made in a separate manufacturing step as separate items.
  • connecting device can be used in principle all suitable material or positive connections.
  • crimping or edging operations as well as welding or soldering are particularly preferably suitable for connecting the bearing ring and the manufacturing ring according to the method according to the invention. .
  • FIG. 1 an inventive adjusting ring 1 for adjusting the blades of a VTG diffuser of exhaust gas turbochargers is shown.
  • the adjusting ring 1 has a bearing ring 2, which is provided for guiding suitable bearing bodies (rolling elements).
  • the adjusting ring 1 has a lever engagement ring 3, which has a plurality of circumferentially arranged grooves, one of which is designated by the reference numeral 5.
  • Fig. 1 clarifies, the adjusting ring with its two components bearing ring and lever engagement ring 3 is a circular Component in Fig. 2 is again illustrated along the section line AA.
  • Fig. 2 illustrates here that the bearing ring 2 and the lever engagement ring 3 are connected via a connecting device 4 with each other after their preparation as individual parts to form the adjusting ring 1 in its entirety.
  • the connecting device 4 is in this case illustrated by the dividing line between the bearing ring 2 and the lever engagement ring 3 and can be generated by one of the above-explained methods of production.
