Gear testing (HaDES)
The test facility HaDES (Harmonic Drive® Experimental Setup) enables to test harmonic-drive® gears for their lifetime under vacuum.
Environments vary from vacuum, non-aggressive gases (e. g. CO2) under controllable pressures (e.g. to simulate Martian environment) or to air with controlled humidity. The tests can be performed at temperatures from -150°C to +200°C.
Harmonic-drive® gears can be used in drive units for e.g. solar array panels, antennas. Therefore lifetime and performance can be measured in HaDES test facility.
Post-Analysis may cover inspection of the gear parts with SEM to detect wear mechanisms or material transfer.
The device is fully PC-controlled. To the control parameters, e. g. sliding distance, motion profiles (unidirectional, oscillating) can be selected. On-line-data acquisition offers to post-process data, e. g. for automatic calculation of efficiency or stiffness.
