FIELD: machine building.
SUBSTANCE: hydraulic machine comprises wheel fitted on shaft, both running about axis X5. Hydrostatic or hydrodynamic bearing 100 with water lubrication is composed of shaft radial peripheral surface 52 on one side and on the opposite side by inner radial surface 102 of member 101 fixed relative to said axis. Said bearing is arranged between two edges 121 and 122 to make water film removal zones created in standard operation of bearing 100. Said fixed member 101 has cavity 130 exposed to its inner radial surface 102 nearby bearing first edge 121 of said first and second edges 121, 122. Said fixed member comprises means 131, 132, 133 to communicate said cavities with those outside the bearing 100, nearby second edge 122. Said cavity 130 and said means 131, 132, 133 can remove flow parts that form water film in case removal of water film at the level of said first edge is impossible.
EFFECT: reliable operation of the bearing.
