| 摘要 |
The present invention improves the cooling performance of a bearing by applying a bump foil in a dual structure to face the bearing installed on a turbine device of a complex thermal power plant and allowing outside air and a cooling fluid to flow in through one or more flow passages penetrating toward the bearing. A steam turbine power plant device has the convex bump foils to make the protruding part of the bump foil face the bearing. Thus, the present invention improves damping effects by increasing areas which come in contact with each other to be rubbed against each other; and absorbs and buffers the power generated by supporting the bearing with the dual structure bump foil. |
