Abstract

PURPOSE:To improve load capacity under low speed rotation by making vents for communicating the outer face of a sleeve and a radial bearing face while facing with a tubular screen fixed to a fixing table, thereby blocking lubricant dispersed through the vents and employing for lubrication. CONSTITUTION:A sleeve 3, a polygon mirror 14 and a second screen 17 are rotated integrally through rotation of a rotor magnet 16, and dynamic pressure is produced through dynamic pressure producing grooves 7a, 8a formed in a fixed shaft 1 so as to form a film of lubricant LU in the gap RC of a radial bearing. An oil film is also formed in the gap RS of a thrust bearing, and the sleeve 3 is supported radially and axially with respect to the fixed shaft 1 and lubricated. Foam in the lubricant LU is discharged through an air vent 9 and a side vent 10 then received by a first screen 11, and thereby the poligon mirror 14 is protected from contamination thus preventing lubrication trouble. Consequently, lubrication is achieved resulting in improvement of load capacity under low speed rotation.
