Couplings kit (PT 500.13)

vibration analysis of couplings

CodePT500.13

Description:

  • Rotating machine elements are interconnected by way of couplings.
  • A coupling exhibiting production or assembly faults generates machine vibrations which can be analysed to give an indication of specific faults or damage.
  • The PT 500.13accessory set can be used to simulate various faults and investigate their effects on vibration behaviour.
  • The properties of various coupling types can also be compared.
  • The curved teeth, pin, flange and claw coupling types are investigated.
  • The couplings are installed between the motor and the shaft.
  • The PT 500.05load unit will also be required to investigate the behaviour of the couplings under load.
  • 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 500.04is required.
  • It includes all the necessary sensors, a measuring amplifier and analysis software to record the vibration phenomena
