Abstract
Official abstract text for this publication.
A method for filtering a fluid that includes collecting contaminates in the fluid, passing the fluid from inside an internal cavity of a first shaft through a tight clearance at a spline connection between the first shaft and a second shaft such that the fluid is filtered of contaminates as a result of the tight clearance, and delivering the filtered fluid to a delivery location.
First claim
Opening claim text (preview).
1 . A method for filtering a fluid, the method comprising: collecting contaminates in the fluid; passing the fluid from inside an internal cavity of a first shaft through a tight clearance at a spline connection between the first shaft and a second shaft, such that the fluid is filtered of contaminates as a result of the tight clearance; and delivering the filtered fluid to a delivery location. 2 . The method of claim 1 , further comprising directing contaminates to a periphery of the spline connection through a centrifugal action. 3 . The method of claim 1 , further comprising delivering the filtered fluid to the delivery location through a supply hole in the second shaft. 4 . The method of claim 1 , wherein delivering the filtered fluid to the delivery location comprises delivering the filtered fluid to a bearing. 5 . The method of claim 1 , further comprising maintaining the fluid at approximately atmospheric pressure. 6 . The method of claim 1 , wherein the fluid is filtered of contaminates sized greater than approximately 0.010 inch (0.025 cm).
