Definitions

  • the invention relates to in only one direction of rotation
  • Blade angles to the circumferential plane of the fan wheel are often complex, in particular with regard to the conversion of the fan blades in their fan angles to opposite conveying directions via an envelope plane lying transversely to the circumferential plane of the fan wheel.
  • the invention has for its object to show ways in which simplifications in this regard both with regard to the functional requirements and in terms of
  • One possibility according to the invention in this regard is, in particular, triggered by speed reduction of the Drive of the fan wheel up to the area of the interruption of the drive
  • the solution according to the invention can be implemented largely without additional effort and in particular also with customary measures, since controlling interventions on the drive of the
  • Direction of rotation of the fan wheel from the opposite to Direction of conveyance-oriented adjustment of the blade angle are dependent, whereby, starting from a suction operation and with the same direction of rotation of the fan wheel, the fan blades about their blade axes via a to the circumferential plane of the fan wheel
  • the changeover of the fan wheel between suction and blowing operation can be initiated solely as a function of the change in the drive speed, and this almost without any control effort, but possibly in
  • the fan wheel is referred to a simplified one below
  • Fig. 1 is an end view of the fan wheel with the central, driven hub radial fan blades, each corresponding to the desired direction of conveyance to the circumferential plane of the fan wheel under one

  • Fan wheel to be driven a flowchart for the changeover of the radial fan blades mounted in its hub and rotatable about their radial wing axes to the hub in the opposite conveying direction, in which the fan blades are rotated about their wing axes for the changeover to the opposite conveying directions via an envelope plane perpendicular to the rotating plane of the fan wheel at which the
  • opposite conveying direction is triggered by reducing the speed of the drive of the fan wheel and in which the fan blades are aligned with their conveying direction by the resulting inertia-related rotation of the fan wheel.
  • a fan wheel according to the invention is illustrated with respect to its most important components and designated 1 overall.
  • the fan wheel 1 has a hub 2 centrally, to which the circumferentially radially projecting the
  • Fan blades 3 are arranged.
  • the fan blades 3 are, as shown in FIG. 3, about their radial ones via wing pins 4 on the foot side Blade axes 5 are rotatably supported in the hub 2 and each by rotating them about a rotation plane 6 of the fan wheel 1
  • the drive 10 of the fan wheel preferably an electric motor, is arranged to support the hub 2.
  • Drive 10 can be rotated in relation to the hub 2 in a manner limited by stops.
  • pin-like stop elements 11 are provided in a cover part 13 of the hub 2, to which a bottom part 14 enclosing the drive 10 radially in the area of the wing pin 4 corresponds to the drive 10 on the end face, which engage in guideways 12 of the cover part 13 and thus the rotational play of the drive 10 for

  • the fan blades 3 Due to the stop-limited rotatability of the hub 2 against the drive 10, the fan blades 3 are at the same level in the opposite conveying directions via the envelope level 9
  • the fan wheel 1 is to be used as a suction or blowing device, that is to say to operate in a suction operation, for example, in a suction mode or a blowing cleaning operation, when the fan blades 3 are switched to the fan blade 3 when the fan blade 3 swings through the envelope level 9 each opposite direction of conveyance. Regardless of the conveying direction, the fan blades 3 are each air-loaded on the same blade side, the front side 21, so that the same for suction and blowing operation

Now, however, in reverse of the previous process by increasing the speed, in particular sudden speed increase, which leads to the fan blades 3 turning over the change-over level 9 to a suction mode.
  • Such a redirection of the fan wheel 1 with respect to the conveying direction can also be carried out according to the invention
  • Adjustment options of the blade angle 7 of the fan blades 3 can be combined in relation to the amount of air conveyed, which opens up further possible uses.
