What I had in mind for the grav ring is actually a bit more sophisticated.
First of all, there has to be sufficient structural reinforcement to hold the ring to the hull during maneuvers. Secondly, when combat conditions may come up unexpectedly, we -cannot- have a moving structural member blocking use of our thrust units.
So my idea was that the ring itself is an armored shell, possibly fitted with direct-fire weapons and a SIF generator, with one or more fixed pylons connecting it to the hull and providing access tubes and storage space. Inside this shell would be the rotating section, 'floating' on bearings with a series of rotating locks to enter and leave it. (Making use of these would be a somewhat disorienting experience at first, as what happens is you go into what looks like an elevator, then the rotating bit comes by and 'hooks' it and it twists up through an opening in the two decks to deposit you on the grav deck, so you're undergoing a quick head-to-foot 180-degree rotation.)
Also, something else to remember: Subs are not terribly large. The primary pressure hull, not counting the extended boom for the engine, is going to be about 200 meters total length. It might have a beam of 10-12 meters.
There is not going to be a great deal of room in the grav ring. It will probably be wider than I've depicted it, but have only one deck and a crawlspace for emergencies. --
