Abstract
Aspects of the present disclosure relate to a skewed roller impeller cage including a metallic ring with radially arranged slots in which rollers are positioned. Impeller shaped channels are defined around a top side of the cage to force fluid to circulate from an outer diameter of the cage to an inner diameter of the cage and vice versa. Cutouts defined at the inner diameter of the cage allow fluid to circulate from the top side of the cage to the bottom side due to centrifugal forces moving the fluid from the inner diameter back to the outer diameter of the cage to allow for continuous circulation of the fluid about the cage.
Claims21
A skewed roller assembly, comprising:
- a disc having a first side and an opposite second side, the disc including an inner diameter and an outer diameter;
- a plurality of skewed slots defined through the disc;
- a roller retained in each one of the plurality of skewed slots;
- a first plurality of impeller flow channels defined on the first side of the disc;
- a second plurality of impeller flow channels defined on the second side of the disc, wherein the second plurality of impeller flow channels are formed in a reverse orientation to the first plurality of impeller flow channels;
- and
- cutouts positioned adjacent to the first and second pluralities of impeller flow channels to provide a fluid entrance and a fluid exit for continuously circulating fluid around the disc.
A skewed roller assembly, comprising:
- a disc having a plurality of skewed slots defined therethrough;
- a roller retained in each one of the plurality of skewed slots;
- and
- a plurality of impeller flow channels defined on a first side of the disc, each of the impeller flow channels extending past a respective one of the skewed slots so that each roller extends across a respective one of the impeller flow channels.
A disc for use in a skewed roller assembly, comprising:
- a main body defining a plurality of skewed slots entirely through the main body, wherein the skewed slots are skewed at an angle to a radius line of the main body;
- a first plurality of impeller flow channels defined on a first side of the main body;
- a second plurality of impeller flow channels defined on a second side of the main body, wherein the second plurality of impeller flow channels are formed in a reverse orientation to the first plurality of impeller flow channels, the first and second pluralities of impeller flow channels each having entrance and exit points at an inner diameter of the main body, and wherein each of the first and second impeller flow channels extending across a respective one of the skewed slots.
A disc for use in a skewed roller assembly, comprising:
- a main body defining a plurality of skewed slots through the main body;
- a first plurality of impeller flow channels defined on a first side of the main body, each of the first plurality of impeller flow channels extending from an outer diameter to an inner diameter of the main body;
- a second plurality of impeller flow channels defined on a second side of the main body, wherein the first and second plurality of impeller flow channels are oriented at an oblique angle to a radius line of the main body from the outer diameter to the inner diameter, wherein the second plurality of impeller flow channels are formed in a reverse orientation to the first plurality of impeller flow channels, the first and second pluralities of impeller flow channels each having entrance and exit points at the inner diameter of the main body.
