Abstract

Ein Axialventilator mit einem Laufrad (1) und verstellbaren Flügeln (2) wird angegeben, wobei das Laufrad (1) einen Tragring (5) aufweist, in dem mit den Flügeln (2) verbundene Holme (11) drehbar gelagert sind. Dabei besteht die Lagerung jedes Holmes (11) aus einem innen am Tragring (5) anliegenden Wälzlager (14) und einer außen am Aufsatz (13) anliegenden Büchse (15). Weiterhin ist der Holm (11) durch eine auf das äußere Ende des Holmes (11) geschraubte Holmmutter (19) in dem Tragring (5) fixiert.

Figure imgaf001
An axial fan with an impeller (1) and adjustable wings (2) is specified, wherein the impeller (1) has a support ring (5) in which with the wings (2) connected spars (11) are rotatably mounted. The storage of each spar (11) consists of an inside of the support ring (5) adjacent rolling bearing (14) and an outside of the attachment (13) adjacent sleeve (15). Furthermore, the spar (11) by a on the outer end of the spar (11) screwed Holmmutter (19) is fixed in the support ring (5).
