PT 500.10 Elastic shaft kit

FEATURES:

 

  • Flexural vibration of the elastic shaft
  • Resonance and critical speed

DESCRIPTION

Technical Description

This accessory setup 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 setup is mounted on the base plate of the machinery diagnostic PT 500 base system. 

To measure and evaluate the experiment, the computerised vibration analyser PT 500.04 and two displacement sensors PT 500.41 are required. It includes all the necessary sensors, a measuring amplifier and analysis software to record the vibration phenomena.


Learning Objectives / Experiments

- familiarisation with the terms 'critical speed’ and 'resonance'
- influence of unbalanced excitation
- balancing the elastic rotor
- influence of alignment errors
- understanding and interpreting frequency spectra
- use of a computerised vibration analyser together with two displacement sensors PT 500.41
- study of the orbit in the subcritical and supercritical range
