  • Patent number: 6705431
    Abstract: A rotational-part supporter has a structure in which one of either an inner part or an outer part is fixed, and the other one is rotated, and a main rotational shaft lies between the inner and outer parts. A revolving speed below a revolving speed based on a lubrication lifetime predicted for each rotational bearing (3) is stored in a memory (61) disposed in the lubricant supply controller (6). When a revolving speed obtained by actual rotation coincides with the stored revolving speed in the rotational bearing (3) after supplying the lubricant, the controller (6) issues a signal indicating that the lubricant should be newly supplied, and thereby a safety operation can be realized.

  • Publication number: 20030015374
    Abstract: The invention provides a rotational-part supporter in which one of either an inner part or an outer part is fixed, and the other one is rotated, and a main rotational shaft lies between the inner and outer parts. A number of revolutions below a set number of revolutions based on a lubrication lifetime predicted for each rotational bearing (3) is stored in a memory (61) disposed in a lubricant supply controller (6). When the number of revolutions obtained by actual rotation reaches the stored number of revolutions in the rotational bearing (3) after supplying a lubricant, the controller (6) issues a signal indicating that a lubricant should be newly supplied, and thereby a safe operation can be realized.
