ABSTRACT:
A fan with an anti-leakage device for an oily bearing includes a base, an axial barrel, a fan wheel and a bearing. The axial barrel extends from the base and provides a first end, a second end, a first oil storage groove at the second end. The fan wheel extends a spindle from the inner side thereof and provides a joining part surrounding an end of the spindle and being adjacent to the inner side of the first end. The bearing is received in the axial barrel and further includes an axial through bore, which provides two inverted cone shaped ends, and at least a second oil storage groove, which is provided at a wall surface of the axial through bore for being adjacent to the spindle closely. Thus, a closed circuit is formed for the lubrication oil flowing back to the bearing without leakage.
