Title: Bearing for miniture motor
Inventor: AIZAWA KOUJI
IPC: H02K5/16
Filed: 1977-09-21
Abstract: PURPOSE: To prevent disperse of oil and to improve circulation of oil to the bearing, by fitting oil-containable washer to slip bearing of motor while contacting with bearing end.  
     CONSTITUTION: Oil-containable washer 10 is fitted to bearing frame 3 while contacting with the edge of bearing 2. As shown by arrow in the drawing, oil flowed out to bearing edge by the rotation of shaft 1 is recovered by washer 10 and recirculated through oil-contained wick 4 to the bearing. With said washer 10 oil curtain is formed in chamber 12 at bearing edge, thereby the shaft is functioned smoothly, while since oil is scarcely flowed out to oil finger 5 section oil is never dispersed in spray even during high speed rotation thereby leakage of oil is prevented. Consequently service life of bearing is lengthened
