Annular Joint Design Help
(OP)
I've read that the mating force calculated for an annular joint is typically much higher than what is actually required to assemble the parts (because the calculated value assumes a true axial assembly, while a manual assembler will always be off axis, making it easier to assemble the parts). My question is, how much higher? For example, if I calculate x pounds to assemble two components, will the actual mating force be .1x? .5x? etc...

I think the important point is that you need to use the calculated force in designing assembly tools, but recognize that manual manipulation can assemble the typical joint with less effort. How much less, I don't know, and I'm not sure how one would measure it. I guess you'd need an instrumented hand.

Better to design the parts with gentle lead-in chamfers.

If you bother to actually calculate the stresses associated with your dimensions and tolerances and stay within reasonable limits, and check for chemical compatibility, you should have no problem.

Anyone else have experiences with PC annular joints? The material still worries me for this applications.
