发明名称 BEARING DEVICE AND HYDRAULIC MACHINE
摘要 There are provided a water-lubricated bearing device which exhibits excellent bearing performance, has excellent corrosion resistance, can prevent abnormal bearing wear, and is adaptable when an abnormal event of water level decrease occurs, and a hydraulic machine having the bearing device. A bearing device of an embodiment is a bearing device for a hydraulic machine having a rotary shaft of a vertical shaft, and has a water tank storing lubrication water, and a bearing pad supporting from a radial direction a skirt member provided on the rotary shaft in the lubrication water. The bearing device of the embodiment has a first supporting mechanism slidably supporting the bearing pad from the radial direction in the lubrication water, and a second supporting mechanism slidably supporting the bearing pad from a bottom portion side in an axial direction in the lubrication water. One of a supporting surface supporting the bearing pad in the first supporting mechanism and a supported surface supported by the supporting surface in the bearing pad is formed in a convex shape. One of a supporting surface supporting the bearing pad in the second supporting mechanism and a supported surface supported by the supporting surface in the bearing pad is formed in a convex shape.
