<p>A belt-driven blood centrifuge (20) with side-mounted drive motor (24) for rotating the centrifuge at a rotation speed selected to separate blood components. The centrifuge includes a drive shaft assembly (28) rotated at an input rotation speed and a rotor assembly (200) rotatably linked to the drive shaft assembly rotated at an output rotation speed twice the input rotational speed. A drive motor is provided with a drive pulley to drive a belt (26), a chain, and the like to provide the motive force to rotate the drive shaft at the input rotation speed. In one embodiment, a belt is provided to contact both the pulley of the drive motor and an outer surface of a rotatable shell (32) of the drive shaft assembly. A base (12) is included in the centrifuge upon which the drive shaft assembly is mounted. The drive motor is positioned adjacent the drive shaft assembly and mounted on the base.</p> |
