Elastic shaft kit (PT 500.10)

Elastic shaft kit (PT 500.10)

flexural vibration of the elastic shaft

CodePT500.10

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 safety 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 base system PT 500.
  • To measure and evaluate the experiment, the computerised vibration analyser PT 500.04and 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.
