Patent ID: 7861827

Claim:
An oil supply assembly for a gearbox, comprising: (a) a plate member with opposed first and second sides, the plate member having a first bore formed in the first side which is adapted to receive a first bearing, the two sides separated by a radially-inwardly extending flange which has opposed first and second faces with an inner face spanning therebetween; (b) an annular manifold attached to the plate member on the second side in a fixed relationship relative to the plate member so that it engages the second side and the flange, such that the plate member and the manifold cooperatively define an annular oil gallery, wherein the manifold comprises: (i) a ring portion having radially inner and outer edges; (ii) an inner rim extending axially from the inner edge, the inner rim of the manifold bearing against the inner face of the flange; and (iii) an outer rim extending axially from the outer edge; and (c) a plurality of passages formed in the manifold, the passages cooperating with the plate member to define a plurality of generally axially-directed pathways in fluid communication with the first bore and the oil gallery, the passages being substantially evenly spaced around the circumference of the manifold and extending along a junction between the inner face and the inner rim.
