    摘要： An oil supply assembly for a bearing damper of a gas turbine engine includes an oil supply tube configured to supply oil in a first direction. The assembly also includes a bearing support having a bearing damper path connecting the bearing damper to the oil supply tube and a bearing compartment path connecting a bearing compartment to the oil supply tube. The assembly also includes a check valve disposed within the bearing damper path and configured to allow fluid communication in the first direction from the oil supply tube to the bearing damper and block fluid communication in a second direction opposite the first direction.

    摘要： A housing (1) of a rotary machine comprises a low-pressure side (2) and a high-pressure side (3), working-fluid inlet and outlet channels, and at least one rotor (7), which when the machine is working is urged by a working fluid towards the low-pressure side (2). The rotor includes a thrust balancing arrangement (15, 16) for relieving the load on the thrust bearings (11) of the machine, through the medium of an auxiliary bearing (17) and in dependence on pressure fluid supplied to the thrust balancing arrangement, the pressure of which fluid is contingent on the operating conditions of the machine. A relatively large part of the axial load is taken-up by an auxiliary thrust bearing (17), which is readily replaceable. The auxiliary bearing (17) is mounted on an outermost part of the rotor journal shaft (18), on the high-pressure side (3) of the rotor, between a detachable locking device (27) for the auxiliary bearing (17) and the thrust balancing arrangement. The thrust balancing arrangement is located inwards of the auxiliary thrust bearing and includes two annular piston-cylinder parts (15, 16) which are axially extendible and which are located in a cylindrical recess (14) in the housing (1).

    摘要： A shaft support comprising a shaft supported by a radial and an axial static fluid bearing, which shaft is rotatably arranged in a bearing sleeve and is provided with a flange-shaped compensation member, of which a part is situated in a compensation space. The compensation space is connected to a pressure source so that a radially acting resulting force is exerted on the compensation member and the shaft. The shaft support is particularly suitable for use with comparatively accurate bearings having a comparatively high bearing capacity.

    摘要： A fluid bearing for rotatably supporting a rotary shaft. A bearing member comprises a plurality of U-shaped fluid pockets and a plurality of first land portions formed on the bearing surface of the bearing member. Each of the U-shaped fluid pockets is defined by a pair of axially spaced fluid pockets and a supply groove. Each supply groove is formed in parallel relationship with the axis of the bearing member for fluidically communicating the pair of fluid pockets. Each of the first land portions is formed between the pair of fluid pockets for generating hydrodynamic pressure. Each fluid pocket is provided with two second land portions. Each of the supply grooves is located at a lower position in a gravitational direction in its associated U-shaped fluid pocket. The plurality of U-shaped fluid pockets are arranged symmetrically with respect to a vertical plane which includes the center of the bearing member.
