A bearing device of embodiment is usable for a hydraulic machine having a rotary shaft of a vertical shaft, with a water tank storing lubrication water, and a bearing pad supporting a skirt member on the rotary shaft in the lubrication water. The bearing device has a first supporting mechanism slidably supporting the bearing pad from the radial direction, and a second supporting mechanism slidably supporting the bearing pad from a bottom portion side in an axial direction. 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.

Bearing device and hydraulic machine

In one embodiment, a marine current power generation device has rotary blades, rotating shaft, power generator, guide bearings, thrust collars and thrust bearings. The guide bearing has a second slide surface being slidable relative to the first slide surface of the rotating shaft. The thrust bearing has a fourth slide surface being slidable relative to the third slide surface of the rotary plate of the thrust collar. The materials of the first and third slide surfaces include ferrous materials, stainless materials, Ti, Ti alloy, Co, or Co alloy. The materials of the second and fourth slide surfaces include a resin material filled with a first fibrous member and a second fibrous member. The second fibrous member is smaller than the first fibrous member.

A composite bearing memberincludes: a bearing sliding materialwhose surface contacts a rotating portion; a bearing base materialmade of a material different from a material constituting the bearing sliding material; and a joining layerjoining the bearing sliding materialand the bearing base material. Further, the bearing sliding materialhas a sliding layersliding the rotating portion on a surface. Furthermore, the bearing sliding materialhas, between the sliding layerand the joining layer, a composition graded layerwhich dispersedly contains the same metal material as a metal material constituting the joining layerand in which a content of the metal material is increased toward the joining layer

Composite bearing member, manufacturing method of composite bearing member, bearing device and rotary electrical machine

A sole plate in use for turbine capable of realizing a smooth sliding on a gland pad used in the mounting portion of power generating plant equipment, effectively suppressing a variation in the alignment of a rotating shaft by a reaction due to thermal expansion and the thrust of a gas turbine, and eliminating a regular maintenance such as filing of lubricating oil, and disposed between the gland pad installed on a base and a turbine support part, comprising a sole plate body made of a metal material disposed on the turbine support part sole and a sliding member made of a material with self-lubricity formed on the surface of the sole plate body on the gland pad side.

Sole plate for turbine and power generating plant equipment

A composite material has plate having holes and a bonded to a first member to form an intermediate layer, and a second member which is made of a material different from the first member laminated onto the intermediate layer while charging a portion of the second member into the holes of the intermediate layer to form a composite material . The holes of the plate which forms the intermediate layer have a shape in such that the charged second member exerts a resisting force against a tensile stress applied in a direction perpendicular to the surface of the first member , e.g., a shape having a first hole opened on the side of the second member and a second hole communicated with the first hole and having a space not overlapped with the first hole, or a shape that an opened area on the side of the second member is smaller than that on the side of the first member.
