Abstract

The invention comprises a rotor and a stator for making up a motor. The rotor includes a rotary axle sleeve of a holding axle, several blades disposed on the periphery of the rotary axle sleeve and a magnet on the back of the axle sleeve. The stator includes a housing, a round bearing-holding part in the housing, a small electric machine and a base station for holding the small electric machine. An oil-impregnated bearing set in the round bearing-holding part is divided into upper and lower bearing parts. In the upper and lower bearing parts are disposed plugholes of a rotating axle and on the sandwich surface of the upper and lower bearing parts form dents separately. The dents of the upper and lower bearing parts are closed to form an oil-storage part.

Description

technical field [0001] The invention relates to a bearing and a motor, in particular to an oil accumulating device for bearing parts in the motor. Background technique [0002] PRIOR ART Patent Document No. 2002-34205 disclosed in the Patent Gazette discloses the following technical content, which has a rotating shaft and an oil bearing supporting the rotating shaft, and in the inner peripheral side of the oil bearing is provided a The technical characteristics of the concave part. [0003] In the content of the prior art described in the above-mentioned patent documents, although the manufacturing method of the oil-impregnated bearing is not specifically specified, because the oil-impregnated bearing is provided with a recessed portion for accumulating oil inside, it not only increases the difficulty of processing , and from the structural analysis, it is also difficult to further increase the volume of oil-bearing storage, and there are problems such as limitations to a c...
