  • Hydraulically supported thrust bearing
    Patent number: 4035041
    Abstract: An improved thrust bearing of the double acting type has separate tiltably mounted bearing blocks arranged in plane ring segments on each side of a bearing box. The separate bearing blocks are movably supported on hydraulic pistons which are axially movable in corresponding hydraulic cylinders. The hydraulic cylinders on each side of the bearing box are connected by hydraulic pressure transmitting channels individually to separate hydraulic pressure sources so that each bearing block ring segment will have its own pressure while the bearing blocks within each segment will have the same load.
