| description | A device for centring and rotationally guiding a turbomachine shaft includes a rolling-element bearing outer ring; a bearing support having a radially inner annular surface surrounding the outer ring; a connection structure connecting the outer ring to the bearing support and including an elastically deformable structure; a first cavity formed between the radially inner annular surface and the outer ring to receive a first damping fluid film; at least one second cavity formed between the bearing support and the connection structure which is arranged radially outside the radially inner annular surface to receive a second respective damping fluid film. Such an arrangement allows for the coexistence of damping fluid films having very different damping properties. |
