The invention discloses an integrated water lubrication bearing for a thruster with a hub flange. The integrated water lubrication bearing is mainly composed of thrust discs (2), supporting rings (3), a shaft sleeve (7), a rubber batten (8), a propeller hub copper sleeve (9) and thrust pads (21). The propeller hub copper sleeve is arranged in a propeller hub (1), the two thrust discs are installed at the two ends of the propeller hub respectively, spiral flow channels (22) are machined in the thrust discs, the two supporting rings are arranged on a front guide vane hub (4) and a rear guide vane hub (19) connected with a propeller shaft (6) respectively, and the thrust pads are assembled in fan-shaped grooves (33) in the supporting rings. The thrust pads (21), the thrust discs (2) and the supporting rings (3) form a thrust bearing. The rubber batten is vulcanized on the outer cylindrical surface of the shaft sleeve. The shaft sleeve (7), the rubber batten (8) and the propeller hub copper sleeve (9) form a combined radial bearing. The integrated water lubrication bearing has the advantages that the structure is simple and compact, the cooling effect of the radial bearing and the thrust bearing is improved, the bearing capacity of the radial bearing is improved, and the service life is prolonged.
