Test benches
Our gearbox solutions for test bench applications have mainly the following characteristics:
- Suitability for highly dynamic loads in both directions of rotation
- Resonance-free operation throughout the entire speed and torque range
- Start with high acceleration torque
Depending on the customer’s specification, we equip test bench gearboxes with spindle bearings or with hydrostatic / hydrodynamic journal bearings.
Typical applications are:
- Test benches for high-speed motors
- Wind tunnels
- Spin systems for rotors
- Turbine test benches
Examples of completed customer projects:
Spin test rig
Single-stage parallel shaft gearbox for two selectable output speeds.
The two switching wheels are supported on a common shaft by means of preloaded roller bearings.
Power: 8’000 kW
Output speeds: 4’500 and 2’200 rpm
Electric motor test bench
Single-stage parallel shaft gearbox with double helical gears and spindle bearings.
The gearbox is designed for varying loads up to zero speed. The powertrain can be operated resonance-free throughout the entire load and speed range.
Output speed: 28’000 rpm
Pitch line velocity: 172 m/s
