Definitions

  • the invention relates to an engine cooling fan of a vehicle, which is provided with a dynamic imbalance compensation device.
  • Massive forces or static and dynamic imbalances are generally due to inhomogeneous mass distributions of the rotating assemblies, such as e.g. caused by the rotor or armature of a motor and the fan, as well as by form and position tolerances to the axis of rotation and main axis of inertia of the drive.
  • the shape and position tolerances mean that the axis of rotation and the main axis of inertia no longer collapse.
  • a parallel displacement between the axis of rotation and the main axis of inertia of a cooling fan with a fan wheel accommodated on the rotor shaft this leads, for example, to a static unbalance.
  • a centrifugal moment is generated which equals its effects of a moment unbalance or dynamic imbalance.
  • Dynamic unbalance in engine cooling fans usually causes mechanical vibration.
  • the generated vibrations can extend into the passenger compartment and cause, for example, steering wheel flutter, as well as causing disturbing vibration noises.
  • the force effect caused by the dynamic unbalance is reasonably suspected to sporadically trigger rapid bearing wear on engine cooling fan motors.
  • a balance of the static unbalance is usually carried out to comply with permissible limits. The compensation of the dynamic imbalance turns out to be difficult and very expensive in the often very flat fans.
