Abstract

See full text

To recover the axial forces transmitted by a rotating shaft, a bearing assembly includes a plurality of distributed bearing units. Each bearing unit comprises: a stationary base; a resilient member having a stationary portion and a portion that is completely movable in a main direction of the forces to be supported; and a bearing surface that defines, together with the shaft, a water film. The bearing surface is connected to the movable portion. The minimum radius of the bearing surface is between 1 m and 3 m. The resilient member and the base define at least one water chamber. A plurality of ducts are arranged so as to connect the chambers together, thereby defining a closed circuit.
