A closed chamber (13) is defined in the pool (7) below the carousel (1), and pressurised liquid in the closed chamber (13) provides a positive pressure for supporting the carousel (1) and allowing rotation (4) of the carousel (1).

A motor includes a base, a stator, a dynamic pressure bearing unit and a rotor. The base includes a shaft tube. The shaft tube includes a closed end and an open end. The stator is mounted around the shaft tube. The dynamic pressure bearing unit includes a bearing, a dynamic pressure assembly and a thrust plate. The bearing is received in the shaft tube. The dynamic pressure assembly and the thrust plate are disposed in a position relatively adjacent to the open end of the shaft tube and relatively distant from the closed end of the shaft tube. The dynamic pressure assembly is located between the bearing and the thrust plate. A lubricating fluid layer is disposed between the dynamic pressure assembly and the thrust plate. The rotor is connected to the thrust plate and is rotatably coupled with the bearing.

Flywheel for energy storage, comprising a rotor, a housing enclosure, means for charging energy by transferring electric energy to stored kinetic energy in the rotating rotor and means for discharging energy by transferring stored kinetic energy in the rotating rotor to electric energy, distinctive in that the rotor is vertically oriented, the rotor has mass of over 5000 kg, the rotor comprises a central vertical shaft, a radial bearing is arranged to an upper end of the vertical shaft, an axial-radial hydraulic bearing, or separate axial and radial bearings, is arranged to a lower end of the vertical shaft.

A rotation mechanism includes: a housing; a shaft inserted through a hole provided at the housing; bearings installed at the housing and rotatably supporting the shaft; a rotary member provided at one end portion of the shaft, adapted to be rotated together with the shaft, and having a portion that projects to a radially outer side of the hole and faces the housing with a gap having a predetermined size; and a gas passage adapted to connect the gap to outside of the housing and allow gas contained in a portion of the gap to pass to the outside of the housing.

The axial bearing arrangement comprises a first axial bearing plate (12) and a second axial bearing plate (13) each having an annular ring shape, the first axial bearing plate (12) having a first surface (12.1) axially facing the second axial bearing plate (13) and a second surface (12.2) opposite to the respective first surface (12.1), the second axial bearing plate (13) having a first surface (13.1) axially facing the first axial bearing plate (12) and a second surface (13.2) opposite to the respective first surface (13.1); a spacer ring (14) clamped between the first surfaces (12.1, 13.1) of the first and second axial bearing plates (12, 13), the spacer ring (14) defining an axial distance between the first and second axial bearing plates (12, 13); and a bearing sleeve (15) abutting the second surface (13.2) of the second axial bearing plate (13) and being secured to a compressor block (16). The axial bearing arrangement includes an elastic element (22) axially biasing the first and second axial bearing plates (12, 13) and the spacer ring (14) with a predetermined force against an abutment surface (17) of the bearing sleeve (15).

A self-metering hydrostatic thrust bearing for a small gas turbine engine. The thrust bearing can provide thrust capacity in the fore and aft directions of a hydrostatic thrust bearing using a single source of air. The air supply is directed towards the loaded bearing and away from the unloaded bearing by the self-metering mechanism operated by the thrust load.

A preload guide system guides, in a horizontal plane, movement of a rotation structure having journals rotating around a rotation axis having a horizontal rotation shaft. At right-side surfaces of the journals, guide bearing components press predetermined positions on the same side with respect to an axial-direction reference plane and rotatably support the journals. At left-side surfaces of the journals, guide bearing components press positions corresponding to the guide bearing components at the right side surfaces, and rotatably support the journals. The support systems adjust displacement amounts of the guide bearing components such that a sum of the displacement amounts becomes zero.

An electrical machine includes a stator with a stator body supporting an electrical stator and a rotor.
