I’m thinking that you don’t have a great enough height-to-width ratio and the rotor could get cocked and cause some horrific wear on the end iron.

 

My 2¢

In this case you could machine away one face or both faces and braze two rotors together. One end with the gear and the other without. You could have twice the bearing length, and nearly twice the displacement.

 

Just the crank, rotors and housings would be special. Everything else could be stock pieces. Maybe double the torque, could be direct drive?

 

The rotors can also be TIG welded. Repairs are often required when reducing weight.

 

One complete housing with "O" rings against another machined down without "O" rings. "O" ringed end Irons against non "O" ringed center section.

Can't you hear that?????

  Lynn,

     A simple drawing would help my old brain visualize what the rotor

would look like for a 4 rotor engine on a 2 lobe excentric shaft.......I

presume the rotors would be geared differently to the stationary gears

to maintain the various cycles........
