    摘要: A foil bearing includes an outer member (11), and a plurality of foils (13) that are mounted to an inner circumferential surface (11a) of the outer member (11) and directly face the inner circumferential surface (11a) of the outer member (11) in a radial direction without interposition of another member (such as back foils). The foils (13) each include: holding portions (13a, 13b) that are formed at both circumferential ends and held while in contact with the outer member (11); and a body portion (13c) that is formed circumferentially between the holding portions (13a, 13b) and has a bearing surface (A). At least an end portion on one side in a circumferential direction of the body portion (13c) is raised radially inward with respect to the inner circumferential surface (11a) of the outer member (11).

    摘要: A method of and a device for protecting an electric motor (4) in a pod unit (1) for propulsion of marine vessels against shaft bending shocks when the blades (2) of the pod propeller hit ice blocks or other hard objects, said motor (4) having a drive shaft (3), a rotor (41) and a stator (42), said shocks tending to momentarily bend the drive shaft (3) to such an extent that the rotor (41) will come into contact with the stator (42). In accordance with the present invention, the rotor (41) is prevented from coming in detrimental contact with the stator (42) by providing at least two members (61, 62), which together form a radial plain bearing (6) having mating arcuate bearing surfaces (611 and 621, respectively), which during normal operation of the motor (4) are spaced from one another by a gap and come in contact with one another only at extreme loads with short durations. One of the members (61, 62) is an inner member (61) having a circular circumference that constitutes one (611) of the bearing surfaces (611, 621). The arcuate bearing surface (611) of the inner member (61) is coaxial with the rotor (41) and rotary therewith, and at least one of the other members is an outer member (62), which fixed in relation to the stator (42) and has its arcuate bearing surface (621) coaxial there with.

    摘要: Provided is a floating-sleeve hybrid fluid bearing. The floating-sleeve hybrid fluid bearing may comprise: a bearing housing which is mounted by ring-coupling to the outer circumferential surface of a rotary shaft; and a floating sleeve which is mounted between the rotary shaft and the bearing housing so that there is a gap between the floating sleeve and the rotary shaft, and between the floating sleeve and the bearing housing, wherein the rotation of the floating sleeve is constrained by the bearing housing during the rotation of the rotary shaft, and one side of the floating sleeve in the circumferential direction is open in the radial direction.

    摘要: A cover plate bearing device, a cover plate cleaning device, and a cover plate cleaning method. The cover plate bearing device includes a main body and a gas channel provided on the main body; the main body includes two side walls separated in a first direction, a bottom wall connected with the side walls, and a receiving cavity enclosed and formed by the side walls and the bottom wall; the shape of the receiving cavity matches that of the curved cover plate; at least one gas outlet of the gas channel are provided on the side wall; and the gas channel being adapted for blowing gas with a preset angle towards a side of the side wall facing away from the bottom wall, to prevent a moving fluid from eroding the functional coating of the curved cover plate.

    摘要: A circumferential seal assembly capable of dividing a gas into separate flow paths before communication between a rotatable runner and a pair of seal rings is presented. The assembly includes an annular seal housing, a rotatable runner, a pair of annular seal rings, and a plurality of groove structures. Each groove structure separates a source flow communicated into a feed groove so that a portion enters at least two grooves to form a longitudinal flow therein. Each groove includes at least two adjoining steps defined by base walls. The base walls are arranged along the groove to decrease depthwise opposite to rotation of the rotatable runner. Two adjoining base walls are disposed about a base shoulder. Each base shoulder locally redirects the longitudinal flow to form an outward radial flow in the direction of one annular seal ring. The base walls are bounded by and intersect a pair of side walls. Each side wall includes at least one side shoulder which narrows the groove widthwise and locally redirects the longitudinal flow away from the side wall to form a lateral flow in the direction of the other side wall. Each reduction to the volume of the gas at the downstream end of each groove structure increases pressure and enhances the stiffness of a thin-film layer between each annular seal ring and the rotatable runner.

    摘要: Gas bearing for an aspirating seal assembly is disclosed. The gas bearing includes a bearing body having a bearing surface. The gas bearing further includes a first through-hole disposed in the bearing body, and a plurality of second through-holes spaced apart from each other and disposed around the first through-hole. The first through-hole is characterized by a size, and a first central axis. Each second through-hole is characterized by a size, and a second central axis. The second central axis of each second through-hole in the plurality of second through-holes intersects the first central axis at an angle in a range from about 30 degrees to about 150 degrees or at an angle in a range from about −30 degrees to about −150 degrees. Size of at least one through-hole in the plurality of second through-holes is different from the size of the first through-hole.
