Crank mechanism for gamma stirling engine, and how to design it?

[diah3012]

hello, my name is Diah. I'm an Indonesian Student. I have a final assessment to design gamma stirling type. I'm looking for drive mechanism for gamma stirling type. I've searched in may books and I found three type. it was rombic, ross-yoke and phlips, but I can't find any other information about that.
I hope you are kindfully to help me solve this problem. Thank you

Sincerely,
Diah Alhusna

Can you show your gamma stirling engine design ??

Can you show your gamma stirling engine design ??

I've only done for :
- bore & stroke dimension for piston and displacer
- swept-volume for expansion and compression space
- power output

i can't found any literature about crank mechanism for gamma stirling

I do not understand what you mean !!

The crank design depends on the lay out of your motor, if the cylinder and displacer are parallel you will need two crank pins, the displacer pin leading the power piston by 90*. If the cylinders are at right angles you only need one crank pin, with both con rods connected to this.
