Solution Needed to combine Thrust, Torque and Motion?

spggodd

I have a problem which I cannot crack, I am currently looking into the use of a universal joints but I want to explorer other routes too.

I am working on a gearbox test rig which requires a means of transmitting a thrust (5000 N), a torque (1800 Nm) and a speed (2000 RPM) all in the same "shaft". There is also a requirement for a 32mm rod to travel through the middle of all this.

I also need a means of providing the thrust load, currently the use of a Hollow Hydraulic Cylinder looks to be the most effective solution.

Space constraint of the system (length) is around 14".

The input side will be attached to a spline, the thrust load will have to be applied to this splined shaft, the output end is open to ideas.

Many Thanks!
