ABSTRACT:
According to the present invention, in an adjustable blade shaft bearing in an axial-flow fan with adjustable blades, the adjustable blade shaft bearing or a thrust bearing is packed with an annular cover having a U-shaped cross-sectional configuration and a lubricating oil is sealed in the annular cover.
With the above construction, under the centrifugal force produced by the rotation of the axial-flow fan, the lubricating oil can be forced to act always on the rolling surface. Moreover the devices and machining of parts required in the conventional forced lubrication systems may be eliminated so that the construction may be simplified.
