Transducers promise reliable torque testing
Torque measuring systems are available either as a complete torque transducer or as a separate rotor and stator assembly, ideal for high speed test rig and OEM applications.
This allows further analysis into enhanced characteristics, including torsional vibration - out of balance and unwanted drive vibration components; torsional ripple - gear meshing, blade cycling and offset loading, plus dynamic events including gear changes, braking and acceleration.
In order to analyse these transient events, measurement capabilities have been extended and can now measure data at 15KHz in burst mode and 5KHz in continuous mode.
Selective measurements of small fluctuations in data as low as 1:10,000 of the full shaft torque range are achievable, giving optimum measurement performance and data analysis.
The data can be made available in graphical, analogue or digital formats as required.
Datum Electronics can advise on the most efficient system to provide performance data from a transmission line and provide data analysis in a clear and precise format.
One example of this being used in the field is long-term gear box testing of teeth wear within a drive system.
The solution offered provided the capture of torsional meshing data from the input and the output of a gearbox under test conditions.
From the results of the tests, analysis of the shape of torsional profile, or the teeth as they mesh, could be seen and understood.
Bursts of data were taken periodically over the life of the gearbox providing on-going data for the end user.
The ability to gather this form of dynamic data at 60,000 samples per second from the shaft gave an early indication of the change of the gear conditions and allowed additional analysis to be conducted relating to the input and output work cycles through the gearbox.
