Dynamic pressure bearing apparatus and method for manufacturing thereof |
摘要 |
A dynamic pressure bearing apparatus has a rotatable shaft to which a hub is mounted, a disk fixed to the hub, a sleeve which supports the rotatable shaft, and a dynamic pressure bearing formed between the rotatable shaft and the sleeve. The rotatable shaft is rotatably supported by the dynamic pressure bearing. The dynamic pressure bearing apparatus is manufactured by integrating the hub and the rotatable shaft by fixing the hub and shaft to each other, processing the disk mounting surface of the hub after integration, such that relative accuracy between the rotatable shaft and the disk mounting surface can be obtained, and then assembling the rotatable shaft to the sleeve.
