o-ring constraints and deformations

[ER34]

Good morning to all,
I have a problem with the insertion of o-ring in the assemblies .iam,
often or mounted in frontal lamature to seal water and gas circuits between coupling of two details.
a. I can't bind the or in the lamature using the pin/hole bond, for the moment I'm arranging with "contact group"
b. Is there a way to "deform" or seen that for example in my case I have or with thickness 1.8 mm that I mount in deep lamature 1.4mm?

in the hope of being sufficiently explained I thank in advance for the help.

You can't do pin/hole, you have to make 2 separate constraints, one of axial coincidence and one of a tangency.

for deformation avoids, in my opinion it does not need anything

 

[Tarkus]

but if you use inventor's c.c., do not have a small cylindrical surface inside to allow binding?
I use axial bond with this surface and tangency bond with the bottom of the seat

Thanks, guys.
for the constraints ok but leaving the undeformed or is really ugly. . .

 

[Ilario]

it will be ugly, but having deformed it is not functional.

However it is difficult to place them in the assemblies even when the or are enlarged for mounting on an outside.

if it can be useful I have created this or with ilogic to have deformed representation. there are also two i-mates for positioning.

hi bertu...thank you for your contribution but I can't read the .ipt you have attached, when I try to open it I appear

Hello, er34,
the file I shared was created with the inventor version 2015. the error that returns you is typical of when you try to open from a previous release. What version are you using?
