Abstract
A fluid bearing for use in turbomachinery including at least one bearing pad configured to be arranged about a rotating member of the turbomachinery. Each bearing pad includes an internal cooling opening defined in the bearing pad and an internal channel network defined in the bearing pad with at least one channel node in fluid communication with the internal cooling opening and at least two passageways in fluid communication with and extending from the channel node through the bearing pad. At least one of the passageways extends to an exterior surface of the bearing pad to define at least one cooling discharge opening.
Claims22
A fluid bearing for use in turbomachinery comprising:
- at least one bearing pad configured to be arranged about a rotating member of the turbomachinery, each bearing pad comprising:
- an internal cooling opening defined in the bearing pad;
- and
- an internal channel network defined in the bearing pad comprising at least one channel node in fluid communication with the internal cooling opening and at least two passageways in fluid communication with and extending from the channel node through the bearing pad,
- wherein at least one of the passageways extends to an exterior surface of the bearing pad to define at least one cooling discharge opening, and
- wherein channel support structures are located within the internal channel network.
A bearing pad comprising:
- an internal cooling opening defined in the bearing pad;
- and
- an internal channel network defined in the bearing pad comprising at least one channel node in fluid communication with the internal cooling opening and at least two passageways in fluid communication with and extending from the channel node through the bearing pad,
- wherein at least one of the passageways extends to an exterior surface of the bearing pad to define at least one cooling discharge opening, and
- wherein channel support structures are located within the internal channel network.
A fluid bearing for use in turbomachinery comprising:
- at least one bearing pad configured to be arranged about a rotating member of the turbomachinery, each bearing pad comprising:
- an internal cooling opening defined in the bearing pad;
- and
- an internal channel network defined in the bearing pad comprising at least one channel node in fluid communication with the internal cooling opening and at least two passageways in fluid communication with and extending from the channel node through the bearing pad,
- wherein at least one of the passageways extends to an exterior surface of the bearing pad to define at least one cooling discharge opening;
- a deck plate;
- a central support column connected to an outer radial side of the deck plate, wherein the central support column defines a spherical seat, wherein the internal cooling opening is defined in the spherical seat of the central support column, wherein the central support column defines the internal channel network;
- and
- a plurality of primary support structures connecting the central support column with the deck plate.
