We resumed working on the Starapex engine www.starapex.com in January this year.
The original plan was to incluse a U joint drive shaft to take power from the reciprocating rotary piston.
We found that we could take the power from it using the Mazda rotor and stationary gears. The shaft with the previously stationary gear attached was off set from center by .591 inches.
We found the gear teeth not deep enough to compensate for the small eccentric up and down rotary piston motion.
Earlier this week we discovered a system that provides a direct drive system from the center of the assembly.
The engine we are am making is 9" in diameter and has a 7" diamerter rotary piston 2" thick.
This engine has a small displacement, almost 2 cubic inches but it has ten power strokes every revolution each with substantial leverage.
To eliminate the compression loss We have designed a starapex supercharger with a one cu inch displacement that produces 20 cu inches every revolution. The five sided Teflon piston turns on the drive shaft inside a floating teflon housing that is held in position with a steel housing and side plates.
We are self taught metal workers and would like a second opinion regarding metal contact surfaces. We have found a system for hard surfacing mild steel by heating it for an hour after we have enclosed and covered the desired working surfaces with leather. We then ensure that the metal is non magnetic before we dunk it in cold water.
If a file does not cut into it and we are of the opinion that the apex seals and side seals that are hardened the same way will not penetrate and wear to any great extent. The evidence we rely on is the act of trying to file a file. If we are wrong we would appreciate your advice and comments.
