Key Features
- Demonstrates whirling of shafts with a single rotor across multiple shaft diameters
- Bearing holders configurable for both-ends-fixed or one-end-fixed, one-end-free conditions
- Variac-controlled drive motor allows gradual speed increase through the critical (whirling) speed
- Interchangeable test shafts of 4.75 mm, 6.35 mm and 7.9 mm diameter, two of each
- Demonstrates that a shaft resumes true running after passing through its whirling speed
- Mounted on a sturdy base for stable, repeatable classroom demonstration
Applications
The Whirling Of Shaft Apparatus is used in Theory of Machines and Dynamics of Machinery laboratories to demonstrate critical (whirling) speed phenomena in rotating shafts, helping students understand how shaft diameter and bearing end conditions affect the critical speed at which a shaft becomes dynamically unstable.
