Definitions

  • the present invention relates generally to an impeller, in particular a radial-flow fan or a compressor impeller having a different number of full blades and split blades.
  • impellers are used, e.g., as radial-flow fans or as compressor impellers for an exhaust gas turbocharger.
  • One problem with these impellers is the generated noise, which is often perceived as unpleasant.
  • One measure commonly used for noise reduction consists of equipping the impeller with full blades and split blades. Such an embodiment is known from European Patent 0 439 267 B1.
  • the number of full blades on this impeller may be different from the number of split blades.
  • An object of the present invention is to further reduce the noise emission by an impeller.
  • This object is has been achieved by arranging the full blades and the split blades at a different angular distance and in a different order.
  • the present invention thereby greatly reduces the noise level. Due to these measures, the acoustic power is distributed among several individual tones, the intensity of which turns out to be accordingly lower. Another advantage is that the efficiency and power consumption of the impeller remain almost constant. Due to the use of an alternative material, e.g., aluminum, the mass moment of inertia of the impeller is reduced. In actual practice, this means that a much better response characteristic is achieved in an impeller having a diameter of, for example, 670 mm.
  • FIG. 1 is a perspective view of an impeller in accordance with the present invention
  • FIG. 2 is a sectional top view of the impeller of FIG. 1;
  • FIG. 3 is a sectional side view of the impeller of FIG. 1;
  • FIG. 4 is a side sectional view of an impeller having an integrated coupling.
  • FIG. 1 shows an impeller 1 , in particular a radial-flow fan or compressor impeller. It consists of a cover plate 2 , a base plate 3 , a hub 6 with a mounting hole 7 and blades.
  • the blades of the impeller 1 are configured as full blades 4 and split blades 5 .
  • the geometry of the full blades is not identical to that of the split blades here because the split blades form part of the full blades.
  • the full blades 4 and split blades 5 are arranged at a different angular distance and in a different order, the arrangement and order of which can be seen from the sectional diagram in FIG. 2. For example, the split blade 5 . 1 is followed by a full blade 4 . 1 , then a split blade 5 .
  • the noise generated is further reduced due to the different angular distance and the different order while achieving almost the same efficiency and/or power consumption.
  • the level and frequency of the noise, which is perceived as unpleasant, are reduced by these measures and distributed over a broader frequency band. Due to these structural measures, the acoustic power is distributed among several individual tones, the intensity of which turns out to be accordingly lower.
  • the impeller 1 is preferably made of an alternative material, e.g., aluminum. This results in a significant reduction in the mass moment of inertia.
  • the impeller 1 shown in FIG. 1 also has balancing holes 8 . An imbalance in the impeller 1 is compensated by these balancing holes 8 . This reduces manufacturing costs because it is no longer necessary to mount additional balancing weights.
  • FIG. 2 shows a first area 15 and a second area 16 . Only full blades 4 are arranged in the first area 15 . Both full blades and split blades are arranged in the second area 16 . The order of the full blades 4 . 1 through 4 . 6 and the split blades 5 . 1 through 5 . 4 is irregular in the second area 16 . The angles between two blades on the air intake side and the air outlet side are identical. The angle x 1 between the split blade 5 . 1 and the full blade 4 . 1 thus corresponds to the angle x 2 . The angle y 1 between the full blade 4 . 1 and the split blade 5 . 2 corresponds to the angle y 2 .
  • angles z 1 and z 2 are different from one another, i.e., x 1 is not equal to y 1 and is not equal to z 1 .
  • x 1 is not equal to y 1 and is not equal to z 1 .
  • the order of the full blades 4 and the split blades 5 is not rotationally symmetrical, not even in segments.
  • FIG. 3 shows the impeller 1 in a side view.
  • the direction of flow of the air is indicated with arrows.
  • the air is conveyed by the impeller 1 in the axial direction, i.e., radially outward, from above in the direction of the drawing.
  • FIG. 3 shows the arrangement of the full blades and the split blades between the cover plate 2 and the base plate 3 .
  • FIG. 4 shows the impeller 1 with an integrated coupling and a coupling housing 9 .
  • the coupling housing 9 is integrated into the impeller 1 on the rear side 13 .
  • Reference numeral 10 denotes the connection for a housing, e.g., a gear box.
  • the impeller 1 is detachably connected to a wheel mount 11 by a screw 14 from the front side 12 .
  • the wheel mount 11 is in turn fixedly connected to the coupling and the coupling housing 9 .
  • the impeller 1 is activated or deactivated on the basis of the status of the coupling 9 .
