More like a speed reducer for a gas turbine. note the use of roller lobes and the absence of actual gears even in the subassemblies in the background. Another tattle tale is the very low viscosity most likely high temperature extreme pressure synthetic grease for full cavity filling lube as the unit is being assembled.
