This speed increaser is an evolution of the T-shape gearboxes for which we have gain a sound expertise through the 20 units and more manufactured. Thus we found the usual bevel gears but also intermediary gear trains allowing a vertical offset easily recognizable with this impressive column. This offset is made to answer the best as possible our customer dimension needs. Unlike the other T-shape gearboxes mainly used for test benches, this one is designed for production line with 50 000h lifetime as it is used for engine validation.

  • Output speed : 7 850 rpm
  • HS maximum torque : 1 600 Nm
  • Weight : 1 100 Kg


This T-shape gearbox has a phonic wheel embedded for rotational speed measurement and is also equipped with a torquemeter on HS side. The very low gear backlash gives the test system durability in every validation steps.
