Abstract
In a centrifuge comprising a drive shaft assembly, a diaphragm disposed about the drive shaft assembly reduces noise and vibration. The diaphragm permits the drive shaft assembly to pivot off a vertical axis while substantially limiting horizontal displacement thereof. Also, where a centrifuge includes a rotor shaft and a drive shaft, a member situated between the rotor shaft and the drive shaft substantially limits vertical displacement of the rotor shaft while allowing angular deflection of the rotor shaft with respect to the drive shaft.
Claims7
A centrifuge assembly comprising:
- a rotor;
- a drive shaft;
- a rotor shaft disposed between said drive shaft and said rotor;
- and
- a motor which is capable of rotating said drive shaft thereabout;
- wherein the improvement comprises:
- a limiting member disposed between said rotor shaft and said drive shaft, said limiting member limits vertical displacement of said rotor shaft and permits angular deflection of said rotor shaft with respect to said drive shaft wherein said member comprises a first disk-shaped pad disposed within an axially directed center hole through a coupling and held in place by said coupling.
A centrifuge assembly comprising:
- a rotor;
- a drive shaft disposed along an axis;
- a rotor shaft disposed between said drive shaft and said rotor and along said axis;
- and
- a motor which is capable of rotating said drive shaft thereabout;
- wherein the improvement comprises:
- a limiting member disposed between said rotor shaft and said drive shaft, said limiting member limits vertical displacement of said rotor shaft and permits angular deflection of said rotor shaft with respect to said drive shaft wherein said member comprises a first sleeve that is disposed substantially around an end of said drive shaft, a second sleeve that is disposed substantially around an end of said rotor shaft, and flexible column disposed between said first sleeve and said second sleeve and along side axis.
