  • Drive system for centrifuge
    Patent number: 9101944
    Abstract: A drive assembly for a centrifugal processing system is provided for rotating the yoke assembly (36) about a first axis at a first angular velocity and rotating the chamber assembly (30 coaxially with the yoke assembly at a second angular velocity A drive motor (54) is provided for rotating the yoke assembly at the first angular velocity and simultaneously rotating the chamber assembly at the second angular velocity by means of a stationary first gear (64), a second gear (68) mounted to the yoke assembly that operatively engages the first gear, a third gear (74) rotatably mounted to the yoke assembly so as to synchronously rotate with the second gear, and a fourth gear (76) fixed to the chamber assembly that operatively engages the third gear so as to rotate the chamber assembly (30) relative to the yoke assembly (36) upon rotation of the yoke assembly about the first gear.
