PT 500.10 Elastic Shaft Kit Show data sheet (pdf file) Print page
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.
  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 measurement amplifier and analysis software to record the vibration phenomena.
