Abstract

590,867. Lubricating differential gearing. FORD MOTOR CO., Ltd. April 24, 1945, No. 10303. Convention date, Aug. 30, 1944. [Class 80 (ii)] [Also in Group XXXIV] In a lubricating system for automobile axle differentials, oil carried from the sump 37 by the crown gear 9 is removed from the back face of the gear and transferred to the interior of the differential by a stationary scoop 30 closely spaced from, but not contacting, the gear. The scoop 30 is formed on a ring member 24 journalled on the rotating gear-housing 6 and having a face 25 pressed against a face 17 on the housing by springs 34. Co-acting annular grooves 26, 19 on the faces 25, 17 respectively, and a tunnel 28, connect the scoop 30 to oil holes 21, 22, 23 drilled through the housing 6, thrust washer 12 and side gear 10 respectively. The scoop 30 is held against rotation by stops 32 abutting internal ribs (not shown) in the fixed casing 1. The mouth of the scoop 30 may have one projecting side lip, as shown, or a central vertical wall dividing it into two flared-back side openings.
