Abstract

PURPOSE:To simplify and facilitate a disassembly and assembly of the structure of the dynamic vane bearing means by a method wherein a thrust bearing means is stored in a bearing box storing lubricant oil charged therein and at the same time nonoil feeding radial type bearing means is arranged at the innermost diameter part, then the dynamic vane axis of the dynamic variable vane axial flow fan is supported. CONSTITUTION:Thrust bearing 4 is covered by an annular bearing box 7 and then the lubricant oil is charged in it. The inner diameter part of the bearing box 7 is extended to an outer circumferential part of the impellor hub 2 along the dynamic vane axis 3A so as to form a step 7a engaging with the impellor hub 2 and a nonoil feeding radial bearing 13 is arranged at the innermost diameter part. In this arrangement, each of the thrust load in the dynamic vane axis 3A and the radial load thereof is born by the thrust bearing 4 and the radial bearing 13, respectively, and the bearings 4, 13 are unifyed in the bearing box 7. In this way, a structure of the dynamic vane bearing part may be simplified and its disassembly and assembly may be facilitated.
