Definitions

  • the present invention relates to a conveyor with a rotor having a drive and a non-rotatably connected to a rotor hub of the rotor impeller according to the preamble of claim 1.
  • the present invention therefore deals with the problem of providing for a conveyor of the generic type an improved or at least one alternative embodiment, by means of which in particular the assembly of the conveyor can be made simpler and less expensive.
  • the present invention is based on the general idea, for the first time an impeller of a conveyor, for example.
  • a fan on a rotor hub of a rotor by means of locking connections and thereby comparatively easy and fast and also fix without further fasteners.
  • snap-in connections for example, a simple plugging and locking of the impeller on the rotor hub possible without this, for example, more fasteners, such as screws in particular, would have to be screwed by hand.
  • Such a sliding of the impeller on the rotor hub could also be automated, which would preferably no longer manual mounting would be required.
  • spring elements are provided on the rotor hub or on the impeller, which clamp the impeller against the rotor hub.
  • both a centering of the impeller with respect to the rotor hub can be achieved as well as a stabilization of the individual latching connections.
  • the latching hooks engage in corresponding recesses on the edge of the rotor hub and thereby fix the impeller rotationally fixed to the rotor hub.
  • the rotor hub is likewise pot-shaped and has at least three first and at least three second openings. At least three hook elements and at least three pressure-loaded clip elements are arranged on the impeller in this case, wherein the at least three hook elements engage behind an edge of an associated first opening in the assembled state and the at least three clip elements engage in the associated second openings and thereby the impeller rotatably and fix it to the rotor hub axially free of play by the pretensioning.
  • the first and / or the second openings are preferably arranged in an end face of the rotor hub.
  • the impeller and at least the hook elements are formed as a one-piece plastic injection molded part.
  • the clip elements can also be integrally formed together with the impeller and the hook elements, or as separate metal elements.
  • the one-piece embodiment offers the great advantage that the impeller can be produced relatively inexpensively but still of the highest quality.
  • the impeller 5 and the latching hooks 8 are formed as a one-piece plastic injection molded part.
  • the spring elements 10 are integrally formed with the impeller 5, wherein the according to the Fig. 2 illustrated embodiment of the spring elements 10 is only one possible embodiment, so that such spring elements 10 may also be otherwise formed.
  • the latching hooks 8 are structurally biased radially inward and thereby hold the impeller 5 reliably fixed to the hub 4 with closed snap-in connections 6.
  • the axial length of the individual latching hooks 8 is dimensioned such that the latching connections 6 can only be closed, that is, that the latching hooks 8 engage behind the edge 9 of the wheel hub 4 only if the impeller 5 is pushed in the correct position.
