FIELD: machine building.SUBSTANCE: invention is intended for main thrust-journal bearings of ship shaft lines. Thrust bearing with individual lubricant, having a housing (1) with constantly located in it oil reserve, which has no design possibility to flow down in side cavities, aligned with said cases (8). In housing (1) there are support pads (4), cartridge with balance system (5), device for supply of lubricating fluid. Tank for lubricating fluid consists of central cavity (2) and two side cavities (9) of housing (1), combined with casings (8) and not communicating with central cavity (2) in its lower part, lateral cavities (9) are separated from central (2) by support inserts (6). Device for supply of lubricating fluid have discs (12), upper edges of which are located above level of upper pads (13) arranged in casings (8) and feeding lubricating fluid in central cavity (2) from side cavity (9), combined directly to casing (8), where volume between level of lower edges of discs (12) and upper lubricant level is not less than filled during operation of volume in central cavity (2) between level of constant oil reserve and average radius of upper pads (13). In lower part of side cavities (9) are installed oil supply tubes (10), free ends of which are installed above level of connector, labyrinth type seals contain additional oil deflecting baffles.EFFECT: improved circulation and uniform distribution of oil cavities at operation of bearing in shaft lines, having vertical inclination of up to 5 degrees, simplified assembly and alignment of bearings during installation in shaft train and increasing volume of oil used for lubrication of bearing.1 cl, 5 dwg |
