Abstract
A hybrid bearing may increase heat transfer, bearing load capacity, and bearing life in various applications, including but not limited to radial and axial tilting pad bearings. In the illustrative hybrid bearings, the hybrid bearing may comprise at least one tilt pad that is moveable with respect to a main body and at least one fixed pad that is fixed with respect to the main body. Either the fixed pad or the tilt pad (and/or a surface thereof) may be comprised of a non-metallic material (e.g., a polymer or a ceramic material).
Claims20
A hybrid bearing comprising:
- a. a main body;
- b. a first pad engaged with said main body, wherein said pad includes an active surface;
- c. a non-metallic material engaged with a first portion of said active surface of said first pad;
- d. said non-metallic material engaged with a second portion of said active surface of said first pad;
- and,
- e. a third portion on said active surface comprised of a metallic material, wherein said first and second portions of said active surface are separated from one another by said third portion.
A hybrid bearing comprising:
- a. a main body;
- b. a first pad engaged with said main body, wherein said pad includes an active surface, and wherein said first pad is moveable with respect to said main body in at least one dimension;
- c. a second pad engaged with said main body, wherein said second pad includes an active surface, and wherein a position of said second pad is fixed with respect to a position of said main body;
- d. a non-metallic material engaged with a portion of said active surface of said first pad;
- e. said non-metallic material engaged with a second portion of said active surface of said first pad;
- and
- f. a third portion on said active surface comprised of a metallic material, wherein said portion and said second portion of said active surface are separated from one another by said third portion.
A hybrid bearing comprising:
- a. a main body;
- b. a first pad engaged with said main body, wherein said first pad has an active surface thereon, and wherein said active surface is comprised of a metallic material;
- c. a second pad engaged with said main body, wherein said second pad is configured with an active surface thereon;
- and,
- d. a non-metallic material engaged with a portion of said active surface of said second pad.
