  • Axial fans and fans in general usually have a production-related imbalance, which can lead to unwanted vibrations during operation of the fan.
  • disturbing noises may also occur during operation due to engine and airflow noise of the fans. Such unwanted Vibrations and disturbing noises have to be dampened, especially in comfort applications.
  • a small fan assembly in which between the fan housing and a radially outside of the fan housing arranged fastening part a membrane made of an elastic material is provided.
  • the membrane serves as a vibration-damping suspension of the fan housing in the fastening part in order to reduce oscillations and sound emissions occurring during operation of the fan.
  • a ventilator has been proposed in which the motor is connected via elastic damping means with a starter. ren housing part is connected in order to avoid transmission of vibrations from the engine to the rigid housing part during operation.
  • the present invention seeks to provide a fan unit of the type mentioned in terms of its vibration damping, i. to improve at the same time in terms of its noise and vibration damping, by optimizing the elastic suspension of the axial fan in the support ring.

  • the construction of a fan unit according to the invention allows various embodiments of the suspension of the axial fan in the support ring, which can be used as needed.
  • the various variants form a series so to speak, in each case a Axialventiltor with the same support ring and the same retaining pin can be used to him by means of each selected further embodiment in a Hang mounting housing. This simplifies warehousing and production.
  • the mounting housing may advantageously be formed approximately in the form of a short pipe section, for example as a fixed mounting tube or as a flexible mounting ring.

  • the four fasteners are formed as solid, cylindrical sleeves 25 and the receiving openings 24 as cylindrical through holes for insertion of the sleeves 25.
  • the diameter of the through holes corresponds to the outer diameter of the sleeves 25 or is slightly smaller. In the latter case, the passage openings during insertion of the sleeves 25 are slightly widened and thus held by the elastic elongation of the mounting ring 23 therein. Through the sleeves 25 screws can be performed, by means of which the fan unit 1 can be attached or flanged.
  • the receiving openings 24 are arranged in the mounting ring 23 in receiving plates 26 which are arranged offset relative to adjacent portions of the mounting ring 23 radially inwardly.
  • the receiving plates 26 may have straight surfaces or preferably the curvature of the mounting ring 23 and the support ring 2 adapted.
  • the receiving plates 26 also increase their own strength and rigidity of the mounting ring 23, in particular if they are discontinued in their radial position of adjacent elements of the mounting ring 23, so that 23 steps and / or folds are in the mounting ring.
  • the arrangement and distribution of the receiving plates 26 along the circumference of the mounting ring 23 and the corresponding arrangement of the corresponding retaining pin 9 may be arbitrary.
  • the regular, uniform arrangement in a polygon in order to achieve the best possible centering and guiding of the support ring 2 in the mounting ring 23.
  • the receiving plates 26 may be inserted into the mounting ring 23 or preferably formed integrally therewith.
  • Figures 18 to 20 show the fan unit 1 of Figure 17 in the assembled state, namely Figure 18 is a rear perspective view, Figure 19 is a rear view and Figure 20 is a section AA to Figure 19.
  • the retaining pins 9 are in the insertion openings 10 of the mounting ring 23 and
  • the mounting ring 26 and the mounting plates 26 take on the holding, centering and guiding function of the suspension members of the embodiments according to the figures 1 to 16. It can be seen that the radial inner surfaces adapted in their curvature to the support ring 2 Resting receiving plates 26 on the outside of the support ring 2 and lead it and center.
  • the holding pins 9 can be pulled out of the insertion openings 10, because the mounting ring 23 is formed as a flexible mounting housing 7, which is radially expandable or deformable and in which the suspension members are inserted or integrated.
