The ProTest production test system was used to update the facilities and performance of Gleason gear test machines used to check the quality of differential gear sets. The system was developed to provide fully automated production testing based on gear vibration that not only provides pass/fail warnings for gear quality, but it also automatically evaluates the optimum pinion position for the quietest operation of the given gear pair. This information is then stored with the gear pair and used during assembly to determine the shims required to provide the quietest running condition.production noise and vibration testing of gears
In addition to evaluating the quality of the gear sets, ProTest also automatically acquires vibration data to assess the mechanical condition of the gear test machine itself to ensure the repeatability of the quality testing process.
