PT 500.10

Elastic Shaft Kit

Technical Description

This accessory set-up enables the response of an elastic rotor to unbalanced excitation to be studied. The subcritical, supercritical and resonance running states can be demonstrated. A comparison of the orbits (path curves) in the subcritical and supercritical range is of particular interest.
The field balancing of elastic rotors is another area which can be investigated. The supplied pendulum ball bearings ensure full mobility of the shaft. The retainer bearing limits the amplitudes to harmless values at speeds close to resonance.

The accessory set-up is mounted on the base plate of the machinery diagnostic PT 500 base system.
The PT 500.02 instrumentation kit is required for this experiment. It includes a portable vibration analyser and all the necessary sensors to record the vibration phenomena.

Learning Objectives / Experiments

- Familiarisation with the terms 'critical speed’ and

'resonance'
- Study of the orbit in the subcritical and supercritical

range
- Influence of unbalanced excitation
- Balancing the elastic rotor
- Influence of alignment errors
- Experiment familiarises students with the

fundamentals of vibration measurement methods

for plant/machinery condition monitoring
- Understanding and interpreting frequency spectra
- Use of industrial vibration measuring devices
