Abstract
A porous gas bearing is disclosed. The porous gas bearing includes a housing having a fluid inlet and an aperture. A porous surface layer is disposed within the housing surrounding the aperture in a circumferential direction. The porous surface layer is in fluid communication with the fluid inlet. A damping system includes a damping system including a biasing member, the biasing member being disposed in a passageway that extends along the longitudinal direction of the aperture and circumferentially about the aperture, wherein the biasing member is arranged radially outward from the porous surface layer.
Claims20
A porous gas bearing, comprising:
- a housing having a fluid inlet, a passageway, and an aperture, the housing including a first segment and a second segment disposed radially inward of the first segment, the passageway extending along a longitudinal direction of the aperture, circumferentially about the aperture, and between the first segment and the second segment;
- a plurality of O-rings disposed at ends of the housing to fluidly seal the passageway;
- a porous surface layer disposed within the housing surrounding the aperture in a circumferential direction, the porous surface layer in fluid communication with the fluid inlet via the passageway;
- and
- a damping system including a biasing member, the biasing member being disposed in the passageway, wherein the biasing member is arranged radially outward from the porous surface layer.
A refrigerant circuit, comprising:
- a compressor, a condenser, an expansion device, and an evaporator fluidly connected,
- wherein the compressor includes a shaft, the shaft being supported by a porous gas bearing, the porous gas bearing including:
- a housing having a fluid inlet, a passageway, and an aperture, the housing including a first segment and a second segment disposed radially inward of the first segment, the passageway extending along a longitudinal direction of the aperture, circumferentially about the aperture, and between the first segment and the second segment,
- a plurality of O-rings disposed at ends of the housing to fluidly seal the passageway,
- a porous surface layer disposed within the housing surrounding the aperture in a circumferential direction, the porous surface layer in fluid communication with the fluid inlet via the passageway, and
- a damping system including a biasing member, the biasing member being disposed in the passageway, wherein the biasing member is arranged radially outward from the porous surface layer.
A centrifugal compressor, comprising:
- a shaft that rotates;
- and
- a porous gas bearing configured to support the shaft, the porous gas bearing including:
- a housing having a fluid inlet, a passageway, and an aperture, the housing including a first segment and a second segment disposed radially inward of the first segment, the passageway extending along a longitudinal direction of the aperture, circumferentially about the aperture, and between the first segment and the second segment,
- a porous surface layer disposed within the housing surrounding the aperture in a circumferential direction, the porous surface layer in fluid communication with the fluid inlet via the passageway, and
- a damping system including a biasing member, the biasing member being disposed in the passageway, wherein the biasing member is arranged radially outward from the porous surface layer.
