Belt drive kit (PT 500.14)

vibrations in belt drives



  • When properly designed, manufactured, and correctly set; belt drives are low-maintenance, low-noise, long-life drive units.
  • It is important that the belt should not vibrate and/or slip.
  • The PT 500.14accessory setup can be used to investigate conditions that cause vibration or slip.
  • The effect of disparate elongation on multiple belt drives can be demonstrated by means of individually-adjustable tensioning rollers.
  • The belt drive is a dual belt drive with a belt tensioner.
  • It can, however, also be operated with only one belt.
  • An eccentrically-bored small belt pulley and a damaged V-belt enhance the range of possible experiments.
  • The brake and PT 500.05load unit is required to conduct the experiment.
  • The accessory set PT 500.14can also be used to apply transverse loads in other experiments.
  • The accessory set 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.
