ABSTRACT:
A cylindrical oil distributor insert molded of flexible and resilient fluorocarbon elastomer is self-retaining and self-sealing on an inside cylindrical wall at a hollow end of a rotating shaft. The cylindrical wall of the insert has large and small perforations which define oil catching pockets exposed to an oil spray from a stationary nozzle spraying oil into the hollow end of the shaft. The shaft has drains to each oil catching pocket large enough to exhaust oil from the pockets at rates exceeding the rates at which the pockets capture oil from the spray so that the rates at which the oil is exhausted from the oil catching pockets are proportional to the areas of the pockets exposed to the spray.
