Accurate simulation and management of bearing

[4NX]

In my experience both Inventor and Fusion are very inconvenient with motion carry over from subassembly to assembly. Consider bearing, it can be treat as 2 cylinder components moving on a common axis. In common sense, I will create bearing as an assembly, set up motion link. Then import it to another assembly, with an object bound with outer cylinder another bound with the inner cylinder. In the current assembly, the object bound with outer and inner bearing parts should inherit the motion link previously set up in the bearing assembly. Those objects in relation with bearing components should move along with the bearing components according to the motion link of bearing assembly. However the only way I can achieve an accurate motion simulation with bearing is to break the inner and outer parts to those assembly it moving with, thus I cannot manage the bearing as single entity. I consulted several tutorials on motion link and none touched this problem. Is there a way to do it or not?

Did you post your assembly in the Inventor forum?

You must right click on the sub-assembly and set to Flexible.

I have never experienced the problem you describe - without the files I assume that I must be missing something.

For a bearing, one cylinder is stationary, a Revolve Joint allows for the other to Rotate.

Please describe the “Motion Link”

Bought into an Assembly, you would Joint the primary parts to each part of the bearing.

Something you have not told us?

Might help.....
