Abstract
A housing segment has a fluid inlet and a fluid outlet and a cooling passage therebetween. The cooling passage has a uniform cross-sectional area approximately equal to the cross-sectional area of the fluid inlet and the fluid outlet and may be conveniently formed in a serpentine configuration with loops extending axially. The bearing housing may be mounted over a rolling element bearing to provide a fluid-cooled housed bearing.
Claims10
A fluid-cooled bearing housing for a rolling element bearing, the bearing housing comprising:
- a housing segment having a fluid inlet and a fluid outlet with a cross-sectional area and a cooling passage therebetween, the cooling passage having a serpentine configuration formed by rib portions defining an open groove in a radially outward surface of the housing segment such that the rib portions add strength to the housing segment and provide support for a cover plate;
- and
- a cover plate mounted over the rib portions of the housing segment and covering the open groove such that the cooling passage has a closed uniform cross-sectional area approximately equal to the cross-sectional area of the fluid inlet and the fluid outlet.
A fluid-cooled housed bearing comprising:
- a rolling element bearing;
- a housing segment mounted over the rolling element bearing, the housing segment having a fluid inlet and a fluid outlet with a cross-sectional area and a cooling passage therebetween, the cooling passage having a serpentine configuration formed by rib portions defining an open groove in a radially outward surface of the housing segment such that the rib portions add strength to the housing segment and provide support for a cover plate;
- and
- a cover plate mounted over the rib portions of the housing segment and covering the open groove such that the cooling passage has a closed cross-sectional area approximately equal to the cross-sectional area of the fluid inlet and the fluid outlet.
