| WHIRLING OF SHAFTS DEMONSTRATOR
|
| A base upon which bearing holders and driving motors are coupled.Different bearing can be fitted in a bearing holder to provide different end conditions for test shafts. A variac controls speed of driving motor. The unit demonstrates the phenomenon of whirling of shaft with single rotor. No necessity of applying pretension to shaft. Thus giving a stress free shaft , where equations of deflection can be applied without doubt . Because of single rotor system good results comparable with theory. Demonstration of true running of shafts after passing the critical (whirling ) speed.
