Dynamic Simulation with assemblies within other assemblies

I have a differential with on assembly of two bevel gears within the final assembly of the whole differential. I would like to create a simulation of it working but I cannot get the two bevel gears to rotate together. When I go to add a cone on cone contact jioint between them it does bnot recognmise that they are two seperate parts and wont let me individually select each of them.

Ive got them two gears to spin now and they rotate together properly but how can I get them to rotate at a constant velocity?

In assemble environment, RMB on the subassembly and choose "flexible"
In dynamic simulation environment RMB the revolution joint of your gear, LMB on dot1(R), LMB the most right picture ( = edit imposed motion" ) and add a value.

sorry what does rmb and lmb mean?

ok thanks
