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 500.14 accessory set-up 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 500.05 load unit is required to conduct the experiment. The accessory set PT 500.14 can 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.
The PT 500.02 instrumentation kit is required for this experiment. It includes a portable vibration analyser and all the necessary sensors to record the vibration phenomena. |
