Abstract (en)

[origin: US6507135B1] An axial ventilator has an external-rotor drive motor having an external rotor with a rotor shaft and an internal stator, wherein the external rotor rotates about the internal stator during operation of the external-rotor drive motor. A ventilator wheel driven by the external rotor is provided. A bearing support tube is arranged in the internal stator. A radial plain bearing is arranged in the bearing support tube and supports the rotor shaft. An axial bearing formed by a free end of the rotor shaft and a stationary counter member, against which the free end of the rotor shaft rests, are provided. The stationary counter member comprises a thrust element and an elastomeric shaped member. The thrust element is connected to the elastomeric shaped member. The elastomeric shaped member has a projection on a side facing the thrust element and the thrust element is axially supported on the projection, wherein the elastomeric shaped member is elastically deformable when impacts act on the thrust element in order to absorb, at least partially, the impacts.
