[DE] Die Erfindung betrifft einen Deckenventilator mit einer Mehrzahl von durch einen aus einem Rotor (4) und einem Stator (3) bestehenden Elektromotor in Rotation um eine Achse (1) versetzbaren Flügelelementen (8), wobei der Stator (3) mit der Achse (1) und der Rotor (4) mit den Flügelelementen (8) verbunden ist. DOLLAR A Der Deckenventilator zeichnet sich dadurch aus, dass der Rotor (4) über ein Gehäuse (6) und zwei aus einem Kunststoff bestehende einreihige Schrägkugellager (2) mit der Achse (1) verbunden ist, die in axialer Richtung voneinander beabstandet auf der Achse (1) angeordnet sind.
[EN] Roof ventilator comprises a rotor (4) contained in a housing (6) which is rotates on an axle via two ball bearings (2) made from plastic arranged at an axial distance from each other. Preferred Features: A bearing ring (2.1) is provided and has a recess into which a corresponding protrusion of a further bearing ring fits. A stator (3) is arranged on the axle between the ball bearings and is concentrically enclosed by the rotor. |
