Title:
PIVOT ASSY BEARING AND HARD DISK DRIVE DEVICE
Document Type and Number:
Japanese Patent JP2016085778
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pivot assy bearing capable of more suitably discharging particles.SOLUTION: A pivot assy bearing 1 includes a shaft 12, a sleeve 13 which is provided coaxially with respect to the shaft 12, and a pair of rolling bearings 11 which are arranged to be away from each other in an axial direction between the shaft 12 and the sleeve 13. The sleeve 13 includes a ventilation path for allowing a region surrounded by the shaft 12, a pair of rolling bearings 11, and the sleeve 13 to communicate with the outside of the pivot assy bearing 1 for ventilation. Thus, air flows out to the outside, without passing through a part in which the lubricant of the rolling bearings 11 is enclosed, so that the discharge of the particles from the pivot assy bearing 1 is suitably reduced.SELECTED DRAWING: Figure 3
