Product Description

Crack Detection in Rotating Shaft Kit

Technical Description of Crack Detection in Rotating Shaft Kit

Cracks due to material fatigue are very dangerous for rotating machines. Early detection of any crack is therefore essential before permanent rupture and often fatal consequences can occur. The crack influences the vibration behaviour of the shaft by changing its rigidity. Using suitable analysis software, this change can be registered and inspection of the machine organised in good time. In the experiment, the crack is simulated by an asymmetric flange joint. Variable tightening of the flange bolts produces a temporary gaping of the butt joint, which closely approximates to the behaviour of a crack. The accessory set-up includes two shafts of different lengths: one short and one long. The short shaft simulates a protruding shaft end, and is loaded with the belt drive.
