Abstract: A water lubricated rubber thrust bearing is disclosed in which the rubber bearing surface is formed with a plurality of substantially flat bearing surfaces which are positioned adjacent to a mating flat annular metal bearing surface. The rubber bearing surfaces are separated by radially extending water grooves shaped to facilitate the creation of a lubricating film between the rubber and metal surfaces. The rubber surfaces are arranged so that the pressure per unit area is substantially uniform when the bearing is loaded and the effective area of the bearing is at least equal to about one-half of the area of the associated metal bearing surface.

Abstract: A thrust bearing configured to support axial loads that act on a rotating body includes a thrust shaft rotatably supportable in a bearing housing, a thrust collar, and a retainer connected to the thrust shaft and configured to support a plurality of thrust pieces. The thrust pieces each have a front sliding surface in sliding contact with the thrust collar, and the retainer includes a disk having a central opening and an outer circumference and a plurality of radial incisions extending radially inwardly from the outer circumference which incisions have inner ends radially spaced from the central opening. The radial incisions define circumferentially adjacent spring sections each of the which is individually axially flexible against and away from the bearing housing to open and close a spring gap between each of the spring sections and the bearing housing.

Abstract: A marine vessel propulsion assembly has an elastically suspended gearbox with an output drive shaft guided in an axial bearing with a rigidly suspended bearing housing. Free space is provided in the axial bearing for allowing movement of the output drive shaft in the radial direction, wherein the output drive shaft is freely movable radially within the free space. A supporting ring with sliding elements for axial guidance of the output drive shaft is arranged in the axial bearing. The supporting ring is hydraulically supported by a large number of pistons so that the supporting ring can match itself to angular displacements of the output drive shaft and can always completely and uniformly support the sliding elements on the bearing circumference.

Abstract: A propeller shaft coupling for marine cruisers comprises a casing split longitudinally into two halves which are fastened together by cap screws to clamp the ends of adjacent propeller shaft sections. At the end of each shaft is secured a disc and the coupling has an internal recessed groove for receiving said discs thereby compensating for the tension produced when the power transmission is in reverse.

Abstract: A thrust system for a watercraft including a propeller shaft, a propeller shaft housing and a hydraulic thrust bearing assembly. The propeller shaft has an enlarged diameter shoulder, and the housing is positioned around and allows axial movement of the propeller shaft. The hydraulic thrust bearing assembly is axially constrained between the propeller shaft shoulder and the housing. The hydraulic thrust bearing assembly includes an annular cylinder, an annular piston, at least one oil feed passage and at least one oil bleed port. The annular cylinder surrounds the propeller shaft and has a circular groove. The annular piston surrounds the propeller shaft and is movably positioned within the circular groove of the annular cylinder forming a pressurized chamber. Each oil feed passage and oil bleed port allows oil to be communicated relative to the pressurized chamber. The hydraulic pressure developed in the pressurized chamber is proportional to thrust.
