Test benches
The gearbox that tests other gearboxes – it has to be the best.

Test benches simulate real operating conditions – under controlled, reproducible conditions. To achieve this, the drive technology in the test bench must be precisely controllable, highly dynamic and absolutely reliable over long test series. At the same time, every test bench has different requirements: variable loads, changing speed and torque profiles, and different test specimens and measurement systems.

CHEMNITZER ZAHNRADFABRIK manufactures specialized gearboxes for test bench construction that meet these requirements – designed for the specific test purpose, not for the catalogue.

Typical requirements for the gearbox

  • Generation of defined, reproducible speed and torque profiles
  • High control accuracy and dynamics for rapid load changes
  • Minimal backlash and high torsional stiffness for precise measurement results
  • Integration of sensors, transducers and interfaces for test bench control
  • Simulation of variable loads – from traction and braking torques to fluctuating industrial loads
  • Long-term stability over many operating hours and test cycles

What we offer

Test bench gearboxes are bespoke units that meet high standards – both technically and in terms of deadlines. We work with you to develop the drive solution that best suits your test requirements: from gear ratio design and the integration of measurement technology right through to comprehensive documentation for your test bench qualification. Our design engineers are well versed in the specific requirements regarding backlash, rigidity and measurement accuracy.

Typical gearbox types and application examples

  • High-precision spur and bevel gearboxes for powertrain test benches
  • Load gearboxes for simulating traction and braking torques during vehicle testing
  • Gearboxes with integrated sensors for torque, speed and temperature measurement
  • Special-purpose gearboxes for aerodynamic simulations and wind tunnel drives
  • Test bench drives for industrial machinery, pumps and compressors

Does your test bench have specific requirements for the drive system? We’ll develop the solution – with the precision your test requirements demand.
