Abstract
A system and method to cool a bearing. The system includes a heat pipe extending through a thickness of an inner ring of the bearing from a first surface to an opposing second surface and a cooling lubricant in fluid communication with the first surface. The method includes exposing the first surface of the roller bearing to lubricant and transferring heat energy through the heat pipes.
Claims20
A cooling system for a bearing having an inner ring rotatably carried within an outer ring, the system comprising:
- a heat pipe extending through a thickness of the inner ring from a first surface to an opposing second surface;
- and
- a cooling lubricant in fluid communication with the first surface;
- wherein the heat pipe is configured to come into contact with the cooling lubricant and configured to transfer heat energy from the first surface to the second surface.
1 more element
A roller bearing, comprising:
- an outer ring;
- an inner ring;
- a plurality of roller balls disposed between the outer ring and the inner ring;
- and
- a heat pipe extending through a thickness of the inner ring from a first surface to an opposing second surface;
- wherein the heat pipe is configured to come into contact with a cooling lubricant and configured to transfer heat energy from the first surface to the second surface.
