CETEST’s facilities include test benches for developing endurance and functional tests on gear boxes.
Cetest: Wheels and axles

Our test benches can be adapted to different powers, speeds and torques. We can therefore run any tailor-made testing solution adapted to our client’s needs.

Some of these rigs are prepared for no-load studies and they are rotary, being able to simulate ramps and curves. The main purpose of this test is to run the gearbox with no torque while checking:

  • There is a sufficient amount of oil, which is needed to dissipate the heat generated during this kind of operation.
  • Oil is distributed to all moving elements inside the gearbox (mainly the bearings and gear contact).
  • Initial oil and bearing temperatures for the entire speed range.
  • For external oil leaking out of labyrinths, seals, etc.
Our test benches can be adapted to different powers, speeds and torques. We can therefore run any tailor-made testing solution adapted to our client’s needs.
Cetest: Gearboxes

On the other hand, we also have other test benches for Back to Back load studies; the main purpose of this test is to validate the gearbox under nominal working conditions in terms of speed and torque. This test usually involves simulating several speed-torque blocks:

  • Maximum starting torque.
  • Maximum breaking torque.
  • Maximum gearbox design speed (for worn wheel).
  • Simulation of nominal working conditions with a combination of speeds and torques equivalent (or higher) to those experienced by the gearbox during operation.

The primary parameters checked during the test are bearing and oil temperatures, and vibrations and noise during torque transmission. A grease chemical analysis and bearing inspection are completed after the test.
