Patent number: 8922943Abstract: In a fluid dynamic bearing apparatus, an oil buffer is defined between a thrust gap and a pumping gap. The oil buffer has an axial dimension greater than that of the thrust gap, and/or has a radial dimension greater than that of the pumping gap. An air bubble generated in the thrust gap due to cavitation, for example, when a fluid dynamic bearing apparatus experiences a vibration can be dissolved in lubricating oil provided within the oil buffer. This prevents leakage of the lubricating oil due to the air bubble residing in the fluid dynamic bearing apparatus.Type: GrantFiled: November 18, 2011Date of Patent: December 30, 2014Assignee: Nidec CorporationInventors: Hiroki Yamada, Junya Mizukami, Tsuyoshi Morita, Tetsuya Maruyama, Takuro Iguchi
