Abstract

The invention relates to a fan comprising at least one wheel (2) which is designed to collaborate with a fluid and which is attached to a shaft (3), itself able to rotate about an axis of rotation (X-X'), by clamping between a first supporting member (10) and a second supporting member (11) which are held by said shaft and forced axially toward one another, the first supporting member (10) having, where it meets the wheel, a first substantially conical bearing surface (12) which is substantially borne by a first generator cone (C12) of which the vertex (F12), known as the "first focal point" is directed toward the second supporting member and of which the vertex half angle (0.12) is greater than the grip angle corresponding to the coefficient of friction between said first bearing surface and the wheel. Industrial fans.
