Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A drive for rotating a first structure at a first angular velocity relative to a stationary support and rotating a second structure at a second angular velocity relative to the stationary support about a common axis of rotation, the drive comprising: a rotatable drive shaft supporting the first structure; a drive motor operatively engaging, directly or indirectly, the drive shaft for rotating the first structure; the second structure mounted to the…
