  • Method for manufacturing a fluid dynamic bearing by printing a resin sliding film
    Patent number: 7461455
    Abstract: A bearing apparatus includes a rotating member, a fixed member opposing the rotating member and an ink-like resin material. Opposing surfaces of the rotating member and the fixed member form a bearing part and the ink-like resin material is applied to at least one of the opposing surfaces by transfer printing.
    Type: Grant
    Filed: November 18, 2005
    Date of Patent: December 9, 2008
    Assignees: Nidec Sankyo Corporation, Toyo Drilube Co., Ltd.
    Inventors: Masato Gomyo, Shingo Suginobu, Nobutaka Nagao, Koichi Shoda, Akihito Kobayashi

  • Dynamic pressure bearing device
    Patent number: 7008109
    Abstract: A dynamic pressure bearing device includes a dynamic pressure face of a shaft member, a dynamic pressure face of a bearing member, lubricating fluid filled in a bearing space of a dynamic pressure bearing portion including a gap between the dynamic pressure faces, a dynamic pressure generation means for pressing so that the lubricating fluid generates a dynamic pressure that supports the shaft member in a non-contact manner with the bearing member and in a rotatable manner relatively to the bearing member, and a sliding surface layer having abrasion resistance provided to at least one of the dynamic pressure face of the shaft member and the dynamic pressure face of the bearing member.
