Definitions

  • the invention relates to an axial fan with electric drive according to the preamble of claim 1, known by the WO 03/040570 A1 ,
  • the one by the WO 03/040570 A1 has become known axial fan is used in particular as a cooling fan for engine cooling in motor vehicles.
  • the cooling fan consisting of the axial fan and a driving electric motor, is arranged within a fan frame, which is located in the air flow direction behind a coolant radiator or a multi-heat exchanger existing cooling module. Due to the electromotive drive occur in the drive shaft of the motor torsional vibrations, so-called pendulum moments, which are transmitted to the fan and emitted as sound. Such a fan noise is perceived as unpleasant and is therefore undesirable.
  • the known fan has an approximately cup-shaped hub, which consists of a substantially flat end face and a substantially cylindrical peripheral surface, are attached to which axial blades.
  • the fan is rotatably connected via the end face of the hub with the drive shaft of the motor, wherein the compound is formed bendable soft in the hub area. This should allow a tilting movement between the axis of inertia of the fan and the axis of rotation. Due to the flexurally soft connection of the axial fan to the rotor of the electric drive, the axial fan should align with increasing speed in the direction of the axis of rotation. This is intended to reduce an unbalance moment.
  • the known Axiallspecter torsionally rigidly connected to the motor shaft so that emanating from the engine excitation frequencies are transmitted to the fan, resulting in the unwanted sound radiation.
  • GB 2 265 420 A By the GB 2 265 420 A was an electric blower, consisting of an axial fan and an electric motor, known, wherein the fan is connected via a vibration-damping hub with the motor shaft.
  • the hub is preferably made of an elastomeric, torsional vibration absorbing plastic material which prevents the transmission of torsional vibrations to the fan.
  • a disadvantage of the known fan arrangement is that the hub area is traversed by air - this affects the efficiency and performance of the fan.
  • an axial fan was known with electric drive, wherein between the drive shaft of the motor and fan hub a multi-arm driving element is arranged.
  • the fan hub is attached to the outer ends of the radially arranged radially arranged arms by screw connections.
  • the entrainment element is intended to reduce the moment of inertia of the fan and to prevent tumbling movements of the fan wheel. Torsional vibrations are not damped, but transmitted via the driving element on the fan.
  • the decoupling of torsional vibrations, which emanate from the electric motor with respect to a fan is also known in heating and / or air conditioning systems for motor vehicles
  • Such fan wheels are designed as radial fan wheels, which suck in the air axially and on the periphery arranged radial vanes (blade ring) in the radial outward direction in a blower spiral promote.
  • the radial impeller has a hub, which is connected on the one hand with the motor shaft of an electric motor and on the other hand via spokes, struts or a perforated support disc with the blade ring.
  • connection between the axial fan and the electric motor is formed torsionally soft, d. H.
  • the torque transmitting area between the motor shaft and Axialbeschaufelung is formed in the circumferential direction elastic or yielding.
  • the essentially planar and closed end face can be formed so as to be torsionally soft, specifically by means of a reduced wall thickness.
  • the reduced wall thickness may be formed annular or sector-like, wherein for stiffening the hub, in particular for achieving a sufficient bending stiffness radially extending ribs are provided on the hub, which can also be molded. These ribs on the inside of the hub simultaneously fulfill a cooling function for the electric drive motor.
  • the hub region can also be designed as an open spoked wheel, wherein the spaces between the individual spokes are sealed airtight by a film, in particular an adhesive film.
  • a film in particular an adhesive film.
  • the fan hub can be mounted directly on the motor shaft, z. B. pressed or via an injection-connected with the fan hub metal bush, which is pushed onto the motor shaft.
  • the fan hub relative to the motor shaft via a driving element, which has radially projecting arms for screwing with the Lüfternabe be secured.
  • a driving element which has radially projecting arms for screwing with the Lüfternabe be secured.
  • the screw vibration-absorbing damping elements in particular bushes are arranged made of an elastomeric material, so that a decoupling in the tangential direction is achieved.
  • the radially extending arms in turn yielding in the circumferential direction, d. H. are elastically formed. Also, the decoupling between the motor shaft and fan can be achieved in the circumferential direction.
