Abstract
Official abstract text for this publication.
An assembly for filtering a fluid includes a first rotatable shaft with a first set of splines. The first rotatable shaft has an internal cavity containing the fluid. Also included is a second rotatable shaft with a second set of splines mated to the first set of splines. The second rotatable shaft includes at least a portion of a supply hole. The first rotatable shaft and the second rotatable shaft are configured to convey the fluid from the internal cavity through a tight clearance between the first set of splines and the second set of splines, to filter the fluid, and then out the supply hole.
First claim
Opening claim text (preview).
The invention claimed is: 1. An assembly for filtering a fluid, the assembly comprising: a first rotatable shaft with a first set of splines, wherein the first rotatable shaft has an internal cavity containing the fluid; and a second rotatable shaft with a second set of splines mated to the first set of splines, wherein the second rotatable shaft includes at least a portion of a supply hole, and wherein the first rotatable shaft and the second rotatable shaft are configured to convey the fluid from the internal cavity through a tight clearance between the first set of splines and the second set of splines, to filter the fluid, and then out the supply hole. 2. The assembly of claim 1 , wherein the supply hole is positioned at a location where the first set of splines and the second set of splines mate. 3. The assembly of claim 2 , wherein the supply hole extends radially outward from a tooth tip of the second set of splines. 4. The assembly of claim 1 , further comprising contaminates carried by the fluid upstream from the tight clearance between the first set of splines and the second set of splines. 5. The assembly of claim 4 , wherein the contaminates collect at a periphery of the mated first set of splines and the second set of splines, when the first shaft and the second shaft are rotated. 6. The assembly of claim 1 , wherein the tight clearance ranges from approximately 0.001 inch (0.003 cm) to approximately 0.010 inch (0.025 cm). 7. The assembly of claim 6 , wherein the tight clearance ranges from approximately 0.004 inch (0.010 cm) to approximately 0.006 inch (0.015 cm). 8. The assembly of claim 1 , wherein the first set of splines and the second set of splines are both straight splines. 9. The assembly of claim 1 , wherein the first set of splines are external splines and the second set of splines are internal splines.
