With the new vacuum component test bench, different construction elements can be dynamically stressed in a test cassette under high vacuum conditions in continuous operation.
Specifically, two angular contact ball bearings, two linear roller guides and a ball screw are driven in a closed power flow by a servo-electric motor located outside the vacuum chamber. The components work against coil springs during the lifting movement, which leads to a dynamic load on the components. Different forces can be applied using different strokes.
The frictional forces or frictional torques and temperatures of the individual components can be measured separately. The test is completed when one component fails.
