Take the Design Work Out of Using O-Rings in Design

When designing I needed to know so much more when working with O-Rings, not just the ring I was going to use but also the proper sizing of the groove it needs to reside in. The Design Accelerator inside of Inventor takes care of all that for me.

The O-Ring Generator inserts an O-Ring in a groove. O-Ring Component Generator creates seals and grooves on cylinders and flat surfaces (axial seals). It is not possible to insert O-Rings on non-circular cylinders or custom groove paths for axial seals.

If you insert seals on cylindrical surfaces, precise diameters are required for the rod and the bore. You must create the cylindrical surfaces prior to using the O-Ring Generator.

O-Rings are available in several materials and cross-sections. Only circular cross-section O-Rings are supported. You cannot add materials to the existing O-Rings in Content Center.

Two types of O-Ring seal geometry are supported. Radial seals are located between two cylindrical surfaces. There is a groove in one of the surfaces to contain the O-Ring, and the other surface has the appropriate diameter so the O-ring is properly compressed. Axial seals are on flat surfaces. The circular O-Ring groove is cut into the housing or the cover plate. The diameter of the groove depends on whether it is exposed to internal or external pressure.
