Definitions

  • the invention relates to a fan wheel, in particular a radial fan wheel, with several Scoops and with an end face, in particular connecting the blades, in substantially circular, substantially perpendicular to a longitudinal axis of the Fan wheel arranged cover disc, the inside diameter of the annular cover plate a tubular receptacle for the fan wheel protrudes driving motor, the jacket of which runs coaxially to the longitudinal axis. Furthermore, the invention relates to a fan, in particular a radial fan, with such a fan Fan wheel and with a motor driving the fan wheel.
  • the radial wheel has an annular shape Cover plate (preferably a sheet metal blank), on the outer edge of several Blades or fan blades are attached that extend axially to one another arranged, curved further cover plate or one piece with the Extend ring-shaped blades.
  • annular shape Cover plate preferably a sheet metal blank
  • the sheet metal disk of the well-known fan wheel also called the rear cover plate, which in the is essentially flat, but also - at least in some areas - plate-shaped can have a central opening for receiving the motor, in particular whose rotors.
  • the fan wheel is like this formed that the edge of the cover plate around the opening axially, approximately parallel to the axis, is bent into the interior of the fan wheel, so that a tubular Recording, a so-called passage, is formed for the engine.
  • a tubular Recording a so-called passage
  • the axial with the known fan wheel Motor mounting area also provided with a segmentation. that is, starting from its end region, the tubular are in the jacket Motor mount incisions introduced to the peripheral area in approximately the same Divide areas, but with an increased manufacturing outlay connected is.
  • the invention has for its object with little manufacturing effort to create a fan wheel and a fan of the type described in the introduction, such that, on the one hand, water separation endangering the function of a fan can be counteracted effectively, but none at all structural disadvantages, in particular those related to those described above Lead to problems that have to be accepted.
  • the motor can preferably as an external rotor motor be formed, with advantageously an outer contour of the motor, in particular a Outer contour of a rotor of the motor designed as an external rotor motor, one Press fit with the tubular receptacle of the cover plate of the fan wheel forms.
  • a fan is good in front of it both during operation and when it is at a standstill protected that moisture gets to endangered components, on the other hand it is manufacturing technology with - compared to the fans described - reduced Effort can be made.
  • the invention is an electric motor 1 for driving an embodiment of the invention Fan wheel 2 provided and for this purpose in a tubular receptacle 3 (passage) the fan wheel 2 held.
  • the fan wheel 2 which is in particular a radial fan wheel, has a plurality of blades 4 and a front connecting the blades 4, essentially circular cover plate 5.
  • the cover plate 5 is substantially vertical arranged to a longitudinal axis X-X of the fan wheel 2, the inside diameter Dl of the annular cover plate 5, the tubular receptacle 3 for the motor 1st protrudes.
  • the jacket 6 of the receptacle 3 is cylindrical, the central axis of which Cylinder is formed by the longitudinal axis X-X of the fan wheel 2 (or coaxially with this runs).
  • the cover plate 5 has between a bordering on its outer diameter DA flat edge region 7 and its inner diameter Dl a plate-like curvature 8 and - including the passage - is preferred as a bent stamped part made of sheet metal executed.
  • the electric motor 1 is preferably designed as an external rotor motor, with an over a stator flange 9 stator 10 attachable to a fixed base by a rotor 11 is enclosed.
  • a stator lamination stack 10a of the stator 10 is clearly shown in FIG. 2 and windings 10b. Power is supplied via a Connection cable 12.
  • An outer contour 13 of the motor 1, in particular an outer contour of the rotor 11 of the motor 1 designed as an external rotor forms an interference fit with the jacket 6 of the tubular receptacle 3 of the cover plate 5 of the fan wheel 2.
  • It can preferably be two to eight, in particular - as shown - four, preferably with the same distance from each other (in Fig. 2 each by 90 ° offset against each other) act bulges 14 arranged in the jacket 6.
  • the cover plate 2 in particular in its plane Edge area 7, has passage openings for fastening elements 17 (e.g. pins), the edges 18 of the blades 4 running perpendicular to the longitudinal axis X-X are arranged, with the passage openings and fastening elements 17th a non-positive and / or positive end connection of blades 4 and cover plate can be manufactured.
  • fastening elements 17 e.g. pins
  • Cover plate 20 may be connected to one another.
  • This cover plate 20 can also Have passage openings for fasteners 21, which on the corresponding edges 19 of the blades 4 to be connected to one another are arranged.
  • this is Invention is not limited to the illustrated embodiment, but includes all means and measures having the same effect in the sense of the invention. That's how they go Bulges 14 in the embodiment shown parallel to the longitudinal axis X-X of Fan wheel 2, but alternatively another one would be, e.g. a helical one Course possible.
  • the invention is not based on the combination of features defined in claim 1 limited, but can also be determined by any other combination of certain Characteristics of all of the individual characteristics disclosed can be defined. This means that basically practically every individual feature of claim 1 omitted or by at least one disclosed elsewhere in the application Single feature can be replaced. In this respect, the claim is only as one to understand the first attempt to formulate an invention.
