Lubricated bearing assembly

A bearing assembly comprising:

• an input shaft for transmitting torque, and having an axial centerline axis;
• an output shaft operatively joined coaxially to said input shaft for receiving said torque, said output shaft having a distal end disposed circumferentially on said output shaft;
• an annular bearing split inner race fixedly joined on said output shaft distal end for rotation therewith, said inner race including first and second halves joined together at a radial splitline;
• a plurality of bearing elements disposed circumferentially around said inner race;
• an annular cage joined to said bearing elements to maintain a predetermined circumferential spacing therebetween and including first and second axially spaced apart ends spaced radially above said inner race first and second halves, respectively;
• a stationary outer race surrounding said bearing elements;
• said inner race including a plural number A.sub.1 of circumferentially spaced splitline channels extending radially therethrough at said splitline in flow communication with a circumferentially extending splitline manifold defined between said inner race and said output shaft distal end;
• said inner race first half including a plural number B.sub.1 of circumferentially spaced first channels extending radially therethrough below said cage first end in flow communication with a circumferentially extending first manifold defined between said inner race first half and said output shaft distal end;
• said output shaft distal end including:
• a number A.sub.2 of circumferentially spaced, axially extending splitline feed grooves disposed in an inner surface thereof and joined in flow communication with a respective number of splitline feed holes extending radially through said output shaft distal end for channeling oil to said splitline manifold;
• a number B.sub.2 of circumferentially spaced, axially extending first-manifold feed grooves disposed in said inner surface between said splitline feed grooves and in flow communication with a respective number of first-manifold feed holes extending radially through said output shaft distal end for channeling oil axially over said splitline to said first manifold;
• and said number A.sub.2 being less than A.sub.1, and said number B.sub.2 being less than B.sub.1.
