Err, not certain I followed all of that.   The shaft side gear is rigid with
the block/housing - not the the eccentric shaft  (if I understood you
statement correctly.)  The moving rotor side part of the gear "Pushes"
against the fixed (bolted to the front and rear iron side housings) gear due
to the power stroke. This causes the rotor to "Push-move" away taking its
eccentric shaft journal with it on the journey around the race track.
