Gearbox diagnostics and inspection
|Stork Diagnostic Services is an independent business unit that measures different operating variables and parameters. The unit is able to conduct vibration, torque, infrared and geometric measurements at short notice, anywhere in the world. These measurements allow clients to establish the dynamic behaviour of their installations.|
Visual inspections on machinery are a powerful tool to assess the condition of the machinery. Stork uses different endoscopes, also called boroscopes or videoscopes. The endoscopes are mostly used by the Diagnostic department to inspect bearings of gearboxes and gears in a planetary arranged gearbox. The endoscopes can be equipped differently in order to inspect very small bearings as well as large planetary gearboxes. Pictures are taken or even video can be recorded to present the results of the inspection. Most commonly, pictures are added to a technical report with an analysis of the observed damage pattern, followed by the conclusions and recommendations.

Stork Diagnostic Services uses two systems to conduct vibration measurements: the CSI portable spectrum analyser and the Bently Nevada multichannel real-time analyser. Both systems are used to determine the dynamic behaviour of turbo machinery by measuring housing vibration and axle displacement. We able to measure vibration levels onsite (the spectrum analyser can detect all kinds of errors and/or defects). Should a problem be encountered, its cause will be determined and discussed with the client. Stork Gears & Services may, at that stage, be asked to resolve it.

Stork Diagnostic Services uses a Faro measuring arm to conduct high-accuracy onsite measurements. The data obtained can be used to define overall gearbox geometry or to reverse engineer one or more parts. To this end, the data is imported into a 3D CAD programme and analysed by our engineering department. 3D measurement can also be used to align gearboxes, turbines and bogies.
Using the newest laser equipment, precise measurements accurate to within 0.01 mm can be performed, such as:
Stork Diagnostic Services performs torque measurements where strain gauges are used (gearboxes and propeller shafts). We are able to monitor torque levels continuously. Stork installed many torque systems around the world that are now successfully used to control the drivers load (most commonly diesel engines). These installations prevent unacceptable tensional stresses, which can lead to damage or failure of the installation.

Stork Diagnostic Services measures mechanical and electrical equipment for thermographic infrared emissions. Our Raytek ThermoViewTM Ti30, which is used to measure the temperature of metals and non-metals, has an operating range between 0 and 2500oC (32 to 4820oF).
