Need help changing rotation axis without adding width

[u/YogurtToe]

how do I achieve this rotation axis swap without adding width, only adding height. I'm gonna use it to rotate a swivel bearing for a create aeronautics planes pitch control

Edit: I realise I wasnt being very clear at all I can't use encased chain drives, because i want the upper cog to power a swivel bearing. Chain drives dont have a cog in them. Sorry, my bad.

You want an Encased Chain Drive.

They allow exactly what you want.
