Design o-rings

Insert radial o-rings

When you insert radial o-rings, it is not important if you specify the placement first or if you select the type of o-ring from Content Center. If you select an o-ring type first, the O-Ring Component Generator offers logical options for placement - surface and reference.
  1. On the ribbon, click Design tab Power Transmission panel O-Ring .
  2. Select the cylindrical face.
  3. Select the planar face or work plane to locate the groove. Click Flip to change the direction.
  4. Specify the distance from reference edge to groove.
  5. In the O-Ring area, click the field to select an o-ring. In the Category drop-down menu, select Radial External or Radial Internal. The families are filtered for the appropriate diameter. If no matching families are found, a message displays in the browse window.
  6. Click to select an o-ring.
  7. Click OK to insert an o-ring into the assembly. Click Apply to insert an o-ring into the assembly and leave the O-Ring Component Generator window open.
Note: You can select the o-ring in the O-Ring area before you specify the placement. In the Category drop-down menu, select Radial External or Radial Internal. Then, specify the o-ring placement.

Insert axial o-rings

When you insert axial o-rings, it is not important if you specify the placement first or if you select the type of o-ring from Content Center. If you select an o-ring type first, the O-Ring Component Generator offers logical options for placement - surface and reference.
  1. On the ribbon, click Design tab Power Transmission panel O-Ring .
  2. Select the planar face or work plane to specify the surface placement of the o-ring.
  3. Select reference edge (circle or arc), perpendicular face, or perpendicular work plane to locate the groove. Click Flip to change the direction.
  4. In the O-Ring area click the field to select an o-ring. In the Category drop-down menu, select Axial External Pressure or Axial Internal Pressure. Depending on whether the seal is exposed to external or internal pressure, the diameter of the groove is based on the inside or outside diameter of the seal.
  5. Click to select an o-ring.
  6. Click OK to insert an o-ring into the assembly. Click Apply to insert an o-ring into the assembly and leave the O-Ring Component Generator window open.
Note: You can also select the o-ring in the O-Ring area before you specify the placement. In the Category drop-down menu, select Axial External Pressure or Axial Internal Pressure. Then, specify the o-ring placement.

Pattern radial O-Rings
  1. On the ribbon, click Design tab Power Transmission panel O-Ring .
  2. Select the cylindrical and planar faces as the placement references to specify the surface placement of the o-ring. Click Flip to change the axis direction.
  3. Specify the distance from reference edge to groove.
  4. In the o-ring area, click the field to select an o-ring. In the Category drop-down menu, select Axial External Pressure or Axial Internal Pressure. Depending on whether the seal is exposed to external or internal pressure, the diameter of the groove is based on the inside or outside diameter of the seal.
  5. Click to select an o-ring.
  6. Switch to the Pattern tab.
  7. Select the Axial option.
  8. Enter the count of o-rings and spacing between o-rings.
  9. Click OK.
Note: You can also select the o-ring in the O-Ring area before you specify the placement. In the Category drop-down menu, select Radial External or Radial Internal. Then, specify the o-ring placement.

Pattern axial O-Rings
  1. On the ribbon, click Design tab Power Transmission panel O-Ring .
  2. Select the planar face or work plane to specify the surface placement of the o-ring.
  3. Select a reference edge (circle or arc), perpendicular face, or perpendicular work plane to locate the groove. Click the Flip button to change the direction.
  4. Specify the distance from reference edge to groove.
  5. In the O-Ring area, click the field to select an o-ring. In the Category drop-down menu, select Radial External or Radial Internal. The families are filtered for appropriate diameter. If no matching families are found, a message displays in the browse window.
  6. Click to select an o-ring.
  7. Switch to the Pattern tab. Select a placement option:
    • Rectangular: Select two edges, and enter the count of o-rings and spacing between o-rings.
    • Circular: Select the circular edge, and enter the count of o-rings and spacing between o-rings.
    • Follow pattern: Select the planar face and first occurrence of a pattern.
  8. Click OK.
Note: You can also select the o-ring in the O-Ring area before you specify the placement. In the Category drop-down menu, select Axial External or Axial Internal. Then, specify the o-ring placement.

Edit with the O-Ring Component Generator
  1. Open the Autodesk Inventor assembly with an existing Design Accelerator o-ring.
  2. Select the o-ring, right-click to display the context menu, and select Edit Using Design Accelerator.
  3. Edit the o-ring.

    For radial o-rings, browse for a new family or select a new member from the existing family. You cannot change the placement geometry.

    For axial o-rings, you can change the distance from the edge. Browse for a new family or select a new member from the existing family.

  4. Click OK.
