Crack detection in rotating shaft kit Vibrational behaviour of a shaft with a radial crack Features - vibration behaviour of shaft with radial crack - identification of damage Learning objectives/experiments - change in characteristic vibration behaviour (natural frequency, resonance speed, amplitude and phase of vibrations) due to a crack - crack identification from the change in vibration spectrum - detection of cracks in rotating shafts at the protruding shaft end - understanding and interpreting frequency spectra - use of a computerised vibration analyser - in conjunction with a safety bearing (e.g. from PT 500.10 - elastic shaft accessory setup) -- detection of cracks in rotating shafts (the elastic rotor) Specification [1] investigation of the vibration behaviour of a cracked shaft [2] crack adapter in flange form [3] simulation of the crack by opening bolt joints [4] 4 different sized cracks can be simulated [5] short shaft to simulate a protruding shaft end [6] long shaft to simulate an elastic rotor [7] PT 500.14 (belt drive) generates required bending torque [8] accessory setup for PT 500 machinery diagnostic training system [9] stackable storage system to house the components Technical data Flange diameter: Ø=90mm 6 hexagon flange bolts M8x20 Shafts - diameter: Ø=20mm - short shaft: L=85mm - long shaft: L=200mm - max. permissible bending torques -- short shaft for belt pulley: 15,9Nm -- long shaft for mass disk: 3,9Nm LxWxH: 400x300x120mm (storage system) Weight: approx. 3kg
