Definitions

  • the invention relates to a burst protection device for the centrifugal compressor of an exhaust gas turbocharger, as described by the features of the preamble of claim 1 and a centrifugal compressor and an exhaust gas turbocharger with such a burst protection device.
  • WO 02/090722 A1 describes a burst protection device for a radial compressor of a turbocharger, in which the compressor wheel is surrounded by housing parts which are able to absorb the energy stored in the compressor wheel. Preventing debris exiting the compressor housing is referred to as containment.
  • the housing parts surrounding the compressor wheel in particular the insert wall of the compressor bounding the flow duct, are divided into at least two parts. A radial part in the region of the flow deflection from the axial to the radial and an axial ring, which encloses the inlet region upstream of the compressor wheel. A large part of the energy is dissipated via forces acting radially on the insert wall.
  • the object of the invention is therefore to provide a burst protection device for a centrifugal compressor of an exhaust gas turbocharger, with which the axial displacement of the compressor housing parts can be limited even without precise knowledge of the forces acting in a given space.
  • the goal is achieved by two or more retention measures successively, ie temporally and spatially separated from each other to effect.
  • the energy is gradually reduced and at the same time prevents the forces acting on an uncontrollably high level.
  • the sliding insert wall remains sufficient space for the axial displacement after the engagement of the first retaining element and before a second retaining element is engaged. This is inside the compressor housing enough space is available to reduce the kinetic energy of the cracked compressor wheel.
  • third or further retaining elements can be brought into engagement.
  • Fig. 1 shows a section through the compressor of an exhaust gas turbocharger.
  • the flow path of the air to be compressed is indicated in the figures by arrows.
  • the terms upstream and downstream refer to this flow.
  • Dashed lines indicated on the axis of rotation A arranged the compressor 60, which is surrounded by different housing parts.
  • the terms radial, axial and coaxial refer to the axis of rotation A.
  • the insert wall 10 Immediately radially outside of the leading and through the compressor wheel flow channel 40, the insert wall 10 is arranged.
  • the insert wall 10 delimits the flow channel radially outwards and, depending on the type of attachment of the insert wall to the outer housing parts, from upstream of the compressor wheel 0bis beyond the compressor in the region of the diffuser, which is arranged downstream of the compressor wheel.
  • an outer compressor housing wall 20 Radially outside the insert wall, an outer compressor housing wall 20 is arranged, via which, for example, a Filter muffler 50 or an intake for the supply of air to be compressed is attached to the compressor housing.
  • the outer wall 20 is connected to the insert wall 10 in the region of the diffuser, directly or via further housing parts.
  • the burst protection device In the case of bursting of the compressor wheel 60, the burst protection device according to the invention is intended to brake the insert wall separated in the region of the compressor wheel in the axial direction and thus prevent it from leaving the compressor housing at the axial exit.
  • a radially outwardly projecting, coaxially arranged retaining projection 11 is provided on the insert wall, which is to cooperate in the case of bursting of the compressor wheel with brake elements.
  • These brake elements are formed as formed with a central opening, annular retaining elements 31 and 21.
  • a first retaining element 31 is fastened to an intermediate wall 30 arranged between the insert wall 10 and the outer wall 20.
  • the first retaining element 31 is in direct contact with the retaining projection of the insert wall, so that in the case of the bursting of the compressor wheel, the insert wall is braked directly for the first time in its axial movement.
  • Retaining projection and retaining element can be connected to each other with a collar or successive wedge surfaces or even via a screw.
  • the first braking stage of the burst protection device only after the insert wall has already moved in the axial direction.
  • This embodiment has the advantage that a first impact on the insert wall, which usually leads to the above-described breakage of the insert wall, does not directly affect the braking device and approximately directly damages the first retaining element 31.
  • a second retaining element 21 is offset relative to the first retaining element 31 in the axial direction. It comprises a coaxially arranged circumferential ring with a central opening.
  • the circumferential ring is the radially inner boundary of a support wall 22 which is fixed to the outer wall 20.
  • the support wall may be formed corrugated for additional reinforcement, as indicated in Fig. 1.
  • the relative dimensions of retaining projection 11 and retaining element 21 and 31 can be explained with reference to the schematic representation in FIG. 2.
  • the retaining projection has a maximum outer radius R 11 .
  • the maximum Outer radius R 11 denotes the largest radius of the coaxially arranged retaining projection. If the retaining projection is provided with a wedge surface as indicated in the figure, the maximum outer radius R 11 is the radius of the outermost wedge tip.
  • the retaining elements 21 and 31 have a minimum inner radius R 21 and R 31 .
  • the minimum inner radius denotes the smallest radius of the openings in the retaining elements. If the openings of the retaining elements are provided with a wedge surface as indicated in the figure, the minimum inner radius is the radius of the innermost wedge tip or the narrowest point of the coaxially arranged opening.
  • the maximum outer radius R 11 must be greater than the minimum inner radii R 21 and R 31 Only this ensures that the retaining projection can brake the insert wall on the way in the axial direction by engaging in the retaining elements.
  • the opening radius of the second retaining element 21, that is to say the minimum inner radius R 21 is smaller than the opening radius of the first retaining element 31, that is to say the minimum inner radius R 31 .
  • the retaining projection 11 is basically formed as a cylindrical, circumferential ring.
  • the retaining projection may also be divided along the circumference into two or more sections, so that in the case of bursting of the compressor wheel, the forces acting on the retaining projection and the stresses caused thereby can not spread over the entire circumference.
  • third or further retaining elements may be provided, which are arranged either in the region between the first and second retaining element or farther upstream of the second retaining element.
