Abstract

PURPOSE: To improve the lubricating performance of the bearing and lengthen its life by a method wherein a wick containing oil is contacted with a spherical portion at a nose of a shaft in a small-sized motor for driving a fan of a home electric product, etc.
CONSTITUTION: A motor rotor 3 is fixed to the shaft 6 supported by means of a sintered bearing 5 containing oil, and a bearing support 4 is integrally fastened to a mold by resin 1 with a motor stator 2. A thrust washer 7 and a retaining ring 8 are installed to the shaft 6 to regulate movement in the thrust direction. A solidified wick containing oil is put between a spherical portion A at a nose of the shaft 6 and a thrust pressure receiving plate 11, one portion of the solidified wick containing oil is contacted with one portion of the spherical portion A at the nose of the shaft 6, and lubricating oil is fed to the nose by a capillary phenomenon. Preferably, the solidified wick containing oil is one with elasticity, such as wool felt to which lubricating oil is impregnated or polyurethane foam or the like.
