Abstract

PURPOSE: To contrive long life for a blower as well as to prevent oil effluence by inserting a damper at bearing part on the side of a fan and the fan part.
CONSTITUTION: A damper 22 is inserted at the bearing part on the side of a conventional fan and at the mechanism constituting the fan part. To begin with, the damper is held to the extent of 0.2 at the diameter of the shaft clearance, right after the fan drive, it makes rotation, but it is adhered to a fast disc in the direction of C from 22 to 22' at the time of full pressure. Then, since the damper is rotatingly adhered to the fast disc during drive, none of abnormal noise engenderment is found due to the contact of the internal diameter of the damper with the external diameter of the shaft. The effluent course of oil becomes as shown in 105, so that effluent dripping is eliminated. In consequence, long life of the blower can be maintained.
