Application

DI1 calculates O-Ring seals for radial outer sealings, inner sealings, and axial sealings.

Calculation

DI1 calculates squeeze of the o-ring under consideration of tolerances, reduction of cross section, concentric and eccentric position.

Database

The O-Ring database delivered with DI1 includes all sizes according to DIN ISO 3601-1 (class A and B) for industrial applications (d2=1,78/2,62/3,53/5,33/6.99mm) and sizes for aeronautics (d2=1,8/2,65/3,55/5,3/7,0mm). You can modify and extend records.

Dimensioning and Recalculation

For Dimension, enter the main mounting dimensions, and DI1 searches a proper O-ring from database.

For Recalculation, enter all dimensions and tolerances, and DI1 calculates squeeze and strain. You can also calculate non-standard o-ring seals.

Limits

Results are checked for min and max values of squeeze, elongation, compression strain and groove fill. If overranged, DI1 reports error messages.

Tolerances

You can directly input ISO tolerance terms according to DIN EN ISO 286, and DI1 converts into dimensions.

Interfaces

All drawings and diagrams can be saved as DXF or IGES file to be loaded with CAD programs.

The OLE interface of DI1 lets you import/export data from/to Excel.

HEXAGON-Help System

Auxiliary text and images are available for all dialogue windows. If error messages occur, you can get description and remedy suggestion.
