Damage to gears kit (PT 500.15)

Damage to gears kit (PT 500.15)

vibration analysis of tooth damage



  • The PT 500.15accessory setup is used to simulate typical damage to gears and study its effects on vibration behaviour.
  • Various gear sets with tooth damage are supplied for this purpose.
  • Undamaged gear sets are provided for comparative purposes.
  • The difference between spur toothed and helical gearing can also be demonstrated.
  • The influence of the centre distance and backlash can be studied using adjustable bearing plates.
  • The type of lubrication has a significant influence on the vibration signal, so grease or gear oil can be used for lubrication.
  • The housing, with holes to accommodate sensors, is used for vibration experiments.
  • The transparent housing cover allows the gear to be observed in operation without taking vibration measurements.
  • The PT 500.05brake and load unit will be required to subject the gear unit to 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.
