[0002] Fan motors generally use oil-containing bearings as supports for the rotating shaft. The rotating shaft rotates at high speed in the oil-containing bearings. Due to the negative pressure generated by local vacuum, the rotating shaft absorbs the lubricating oil in the oil-containing bearings for lubrication. At the same time, the oil-containing bearings are fixed to the machine cover through springs and oil covers, and the oil cover is generally riveted to the machine cover through several rivet sheets. As a result, oil sludge can easily flow out of the gap between the oil cover and the machine cover, causing oil leakage, resulting in waste of lubricating oil, and affecting the service life of the rotating shaft and the oil-containing bearings.

The oil cover 5 includes a cylindrical cover body 6, an annular base plate 7 provided at the lower end of the cylindrical cover body 6 and extending outward, and an annular limiting plate 8 provided at the upper end of the cylindrical cover body 6 and extending inward. A retaining ring 9 is provided on the inner edge of the annular limiting plate 8, and a concave ring 10 is provided on the annular base plate 7. The concave ring 10 is provided with a plurality of The annular base plate 7 is recessed downward as a whole, and an upwardly protruding convex ring 11 is provided on the outer edge of the annular base plate 7. The outer edge of the convex ring 11 is extended downward, and a plurality of riveting sheets 12 are extended downward from the outer edge of the convex ring 11. An annular groove 13, a protruding retaining ring 14 and a through hole 15 are provided on the upper and lower side walls inside the casing 1. The concave ring 10 abuts against the annular groove 13, and the convex ring 11 abuts against the protruding retaining ring 14. The riveting sheet 12 can pass through the through hole 15 and be riveted on the casing 1.

[0018] According to the above structure, when the oil cover 5 is installed, the concave ring 10 abuts against the annular groove 13, and the convex ring 11 abuts against the raised retaining ring 14, so that the oil cover 5 can be quickly positioned and installed, and finally it can be directly riveted on the casing 1 through the riveting sheet 12, and the installation efficiency is high.
