Abstract
A drive assembly for a centrifugal processing system is provided for rotating the yoke assembly () about a first axis at a first angular velocity and rotating the chamber assembly () coaxially with the yoke assembly at a second angular velocity A drive motor () is provided for rotating the yoke assembly at the first angular velocity A stationary gear () is mounted coaxially with the yoke assembly, with a drive linkage () comprising a shaft () secured to the yoke assembly so as to be rotatable therewith. The shaft is operatively connected on its first end to the stationary gear (), so that the shaft rotates about its axis as the yoke assembly () rotates relative to the stationary gear. The shaft () is rotatably connected on its second end to the chamber assembly (), so that when the shaft is rotated, the shaft rotates the chamber assembly. Preferably, the yoke assembly () comprises a first arm () and a second arm (), with the chamber assembly () being rotatably secured to the first arm and the first arm being pivotably connected to the second arm, and the shaft () being flexible.
