what ties the unit together axially ? Tracy has the four corner bolts tying
the driven and driving plates together as an assembly.
what keeps them together as a unit in your design?  or am I missing somthing
?

The thrust bearing at the front of the e-shaft
and the helical gear back thrust limited by Tracy's helical
gear back thrust bearing. I don't expect much seperating force
as the rubber blocks can be tailored for that. In other words
molded concave.
