Definitions

  • the present invention relates to a method as defined in the preamble of claim 1 for balancing a fan blade wheel.
  • the method of the invention is simple. In addition, it produces a good blade wheel balance in both axial and radial directions. Moreover, the method of the invention can be applied for fully automated balancing using an appropriate apparatus.
  • Fig. 1 presents an axial impeller according to the invention, designed for use e.g. in air conditioning systems and producing an axial air flow.
  • the impeller comprises a housing and a plastic blade wheel 1 rotatably fitted on a shaft.
  • a hub 11 At the center of the blade wheel 1 is a hub 11 with a hole 12 for a shaft, with blades 13 fitted around the hub, between the hub 11 and a cylindrical outer rim 14.
  • the blade wheel 1 rotated by an electric motor drive comprising a synchronous motor and a frequency converter controlling it, the frequency converter being connected to a 3-phase alternating-current network and producing a sinusoidal output voltage with controlled frequency variation.
  • the stator of the motor may be fixed to the housing around the outer rim of the blade wheel 1 , and the rotor may be integrated with the blade wheel so that it consists of permanent magnets (not shown) fitted on the circumference of the outer ring part.
  • the outer rim 14 is provided with holes 15 going through the outer rim at certain distances between them, these holes being used to hold balancing weights 16 (Fig. 2).
  • the weights 16 are shorter than the length of the holes, so it is possible to set weights 16 to desired depths in the holes as required for axial and radial balancing.
  • the balancing can carried out on a balancing machine having a rotary drive mechanism for rotating the blade wheel.
  • the machine can be so controlled that it will stop the blade wheel at a position where an additional weight 16 is needed.
  • An external cylinder 17 provided in the machine can push/screw the weight 16 to a correct depth. After this, the machine may carry out a test (rotating the blade wheel) to check the balancing.

Abstract

L'invention concerne un procédé d'équilibrage d'une roue (1) à pales de ventilateur comprenant un moyeu (11), une jante (14) et des pales (13) prévues entre les deux. Ladite roue est dotée d'orifices axiaux (15) formés dans la jante, orifices pouvant être dotés de poids (16) destinés à équilibrer la roue et sensiblement plus longs que les poids, lesquels peuvent être installés à différentes profondeurs dans les orifices, de sorte que l'équilibrage requis soit obtenu.
