Definitions

  • the invention relates to a fan assembly according to the preamble of patent claim 1.
  • an impeller is connected to the rotor of a motor.
  • the impeller is usually mounted by screwing it onto a flange that is pressed onto or welded onto the rotor.
  • the impeller can also be pressed onto the rotor by means of a round or square blank, for example, or screwed or welded directly onto the rotor.
  • the object of the invention is therefore to create a possibility for connecting the impeller and rotor, which allows flexible and simple consideration of different D dimensions in production.
  • a rotor is to be understood as a component of a fan which is placed on a drive shaft of a motor or is formed by the drive shaft itself.
  • D dimension means an axial position of an impeller on a rotor.
  • the invention provides a fan assembly comprising a rotor and an impeller, the rotor having an outer lateral surface and the impeller having an inner lateral surface, the outer lateral surface having outer ring segments without a pitch, the outer ring segments running in sections along the circumference of the outer lateral surface, the outer ring segments in are spaced apart from one another in the axial direction, the inner lateral surface having inner ring segments without a gradient, the inner ring segments running in sections along the circumference of the inner lateral surface, the inner ring segments being spaced apart from one another in the axial direction.
  • the outer ring segments enable variable adjustment of the D dimension and several axial positions of the impeller on the rotor. Depending on the requirements, this position can be freely selected and greater flexibility is made possible when manufacturing larger quantities of fans with different D dimensions. Furthermore, it is provided that at least one outer ring segment forms a form fit with at least two inner ring segments in the axial direction, in particular forms a toothing with at least one inner ring segment.
  • each outer ring segment is at least partially conical along the outer lateral surface and/or each inner ring segment is at least partially conical in the course along the inner lateral surface and/or has at least one run-on bevel in the radial direction.
  • outer ring segments are formed with the inner ring segments in the direction of rotation to form a non-positive connection.
  • outer ring segments and/or the inner ring segments extend in the axial direction along the entire height the outer lateral surface and/or the inner lateral surface are formed.
  • this can also improve an operationally reliable connection between the impeller and the rotor, and on the other hand, it increases flexibility and the number of possible D dimensions.
  • outer ring segments and/or the inner ring segments are designed to be symmetrical all the way around, in particular to be interrupted in 1/8 sections.
  • outer ring segments and/or the inner ring segments themselves are designed with mirror-symmetrical geometries for left-hand rotation and right-hand rotation and a centrally located locking groove or locking spring for a locking connection.
  • figure 1 shows a perspective view of a fan assembly 1 comprising an additional in figure 2 Rotor 2 shown separately, as well as an additional in figure 3 impeller 3 shown separately, in which figure 1 an outer lateral surface 4 of the rotor 2 can be seen.
  • the outer lateral surface 4 has gradient-free outer ring segments 6, which run in sections along the circumference of the outer lateral surface 4 and are spaced apart from one another in the axial direction.
  • the impeller 3 has an inner lateral surface 5, said inner ring segments 5 having no pitch and these run in sections along the circumference of the inner lateral surface 5 and are spaced apart from one another in the axial direction.
  • the impeller 3 can be easily and quickly placed on the rotor and fastened to the rotor 2 by means of a rotary movement of the type of a bayonet lock, in particular without additional tools or without additional aids. Additional fasteners can be saved as a result and individual production can be made possible. An adaptation of the D dimension to different requirements can be made possible by using only one version of the assembly.
  • a synopsis of figures 1 , 2 and 3 shows that at least one outer ring segment 6 with at least two inner ring segments 7 in the axial direction a form fit of the type of teeth forms.
  • the outer ring segments 6 are formed along the entire height of the outer lateral surface 4 in the axial direction and the inner ring segments 7 are formed along the entire height of the inner lateral surface 5 in the axial direction.
  • Both the outer ring segments 6 and the inner ring segments 7 are circumferentially symmetrically interrupted in 1/8 sections.
  • each outer ring segment 6 and each inner ring segment 7 is conical in the course along the outer lateral surface 4 or the inner lateral surface 5 and has a starting bevel 8 in the radial direction. It can also be seen that the outer ring segments 6 are formed with the inner ring segments 7 in the direction of rotation to form a non-positive connection.
  • the outer ring segments 6 and the inner ring segments 7 themselves are designed with mirror-symmetrical geometries for left-hand rotation and right-hand rotation and a centrally located locking groove 9 or locking spring 10 for a locking connection.
