Abstract
A system for cooling and lubricating the drive motor of a centrifuge. The shaft of the motor includes an internal passage with an inlet having a size and taper sufficient to provide the desired rate of cooling oil flow through the motor. A lower bearing proportioning arrangement applies a high percentage of a small proportion of the total oil flow to the lower bearing. An upper bearing proportioning arrangement applies a low percentage of a large proportion of the total oil flow to the upper bearing. Together these features assure a high degree of motor cooling without overlubricating the bearings.
