Abstract
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.
