Abstract

A mechanism for driving a centrifuge drum has a shaft housing and a vertical transmission shaft having an upper end on which a centrifuge drum is mountable. Upper and lower bearings mount the shaft for rotation in the shaft housing. A wheel is mounted on the shaft for rotation therewith and a drive belt rotates the shaft via the wheel. An oil pool provides an oil mist for lubricating the upper bearing. The lower bearing is immersed in the oil pool and the wheel is mounted on the shaft above the upper bearing.
