WHIRLING OF SHAFTS AND CRITICAL SPEED

A compact bench top mounting experiment to demonstrate the phenomena of whirling shafts.

The Whirling of Shafts and Critical Speed apparatus shows how shafts vibrate transversely and 'whirl' at a certain rotation frequency. This helps engineers understand possible problems with long shafts and allow for them in their designs. The equipment is in two parts and fits on a bench or desktop.

The main part is a solid alloy frame that holds a variable speed motor which turns the horizontal test shaft. Two bearings hold the shaft, one bearing at the 'driven end' and the other bearing at the 'tail end' of the shaft.

Similar to a beam on two simple knife-edge supports, both bearings allow free angular shaft movement (free ends condition).

Also supplied with the equipment are extra bearings that restrict angular movement when fitted, to give 'fixed ends'.
