  • Patent number: 7941926
    Abstract: An apparatus for manufacturing a hydro dynamic bearing device is provided for the finishing treatment of lubricating oil after lubricating the hydro dynamic bearing device. The hydro dynamic bearing is constructed of an axial member housed in a housing, a radial bearing part for supporting the axial member in a non-contact manner in a radial direction by a hydro dynamic pressure action of the lubricating oil generated in a radial bearing clearance, and a sealing part arranged in an opening part of the housing, and the apparatus has a laser for measuring an oil-level height of the lubricating oil in the housing.

  • Patent number: 6799372
    Abstract: A method for manufacturing a hydro dynamic bearing device is provided. This method is capable of sufficiently increasing a circumferential speed at the time of grinding an axial member which is a structural component of the hydro dynamic bearing device, and also capable of preventing the generation of centrifugal whirling to improve the grinding efficiency and working efficiency while improving the quality of the product. The axial member as one of structural component of the hydro dynamic bearing device is supported at both ends thereof with a pair of plate members in a face-contact manner, while rotating the axial member around its axial center. The outer peripheral surface of the axial part of the axial member is ground on a grindstone while supporting the outer peripheral surface of the axial part with a supporting member.

  • Publication number: 20020193972
    Abstract: A workshop facility designing and operating method of the invention is for authoring a virtual workshop that is a data model of a workshop newly organized in part or in its entirety. After the organization, simulating means causes the virtual workshop to perform a quasi-production activity to verify a production state and a physical distribution state. An actual workshop is then constructed that matches with the verified virtual workshop. The constructed actual workshop is remote monitored and a result of this monitoring is compared with a result of verification during a virtual workshop verification process. In this way, verification of the workshop in its entirety can be performed simply so that workshop deployment such as a new set-up of a production line and change in process step of the existing line can be carried out efficiently and quickly in a short time. Remote monitoring of the constructed workshop can also be performed properly.
