Is that your hand attempting to balance that wrist watch engine crank?
All this design stuff is all very well but what about this TS3 well known engine failure problem?
It needs sorting before going further into these futuristic designs of yours.
Swop your drumsticks for a torque wrench springs to mind.
The answer is all in the clues given?
Merlyn, At the beginning of my project, I also only thought about the torque wrench, for which we have had a long-time sentiment .. but then it turned out that this feliks rollet may have a diameter of 30 mm. And I thought a little, that the diameter of the bearing, it's the approach with the torque wrench that does not fit ... because the screws would probably be 8mm ..
After all, this is a bearing for a piston pin - a bushing made of bronze. And it will end up with drumsticks ...
Of course, I do not exclude the possibility of a traditional torque wrench and classic rotary pins ..
Well now here is a picture as I imagine my Feliks Roller. This is the version of Felix Commer4 of course a two-stroke version. in which the main torsion forces are transmitted through the maximum large areas of the "connecting rod", and are supported at the point where they work, and do not cause bending, as in the classic crankshaft. That is why it does not tend to fatigue the matariału. and relatively long trouble-free work .. And a little lower costs of doing....
Well, of course, the masses reciprocating a little smaller ..
