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.

Abstract: An anti-leakage device for an oily bearing includes a base, a wearing piece, a fastener, a bearing, a spindle and a fan wheel. The base provides an axial barrel. The wearing piece, the fastener, the bearing and the spindle are received in the axial barrel. An oil removing disk is attached to an inner side of the fan wheel and provides a conical shell with a conical hole being enclosed with the conical shell such that the oil removing disk is capable of collecting lubrication oil with centrifugal force and the lubrication oil collected by the oil removing disk passes through the conical hole to allow the lubrication oil flowing outward the oil removing disk being forced to move back to the axial barrel.

The bearing is received in the axial barrel and further includes an axial bore, which provides two cone shaped ends, and at least a second oil storage groove, which is provided at a wall surface thereof for being adjacent to the spindle closely; and a reduced-curve end, which is opposite to the joining part. Thus, a closed circuit is formed for the lubrication oil flowing back to the bearing without leakage.
