WN8 calculates dimensions and load bearing capacity of serrations with straight flanks according to DIN 5481. A true-scale drawing of the spline is generated by WN8 and may be exported as CAD file. Material data are loaded from the integrated material database.

In Pre-Dimension, WN8 calculates a suitable spline size for the required transferable torque.

Standard sizes to DIN 5481 may be selected from integrated database. Or you can enter dimensions for self-defined serration splines.

Integrated material database includes strength values for the most common steeel materials, and may be extended by the user.

Safety against bearable flank pressure is calculated according to Niemann (Maschinenelemente Band 1, 2005)

Profile drawing and tables with most important dimensions and results on one screen.

Calculation results may be printed, saved as HTML table, or directly exported to MS-Excel.

WN8 generates true-scale drawing of shaft and hub profile which may be exported to CAD by DXF or IGES file. Tables with dimensions and tolerances are also generated by WN8.

WN8 generates a production drawing with tooth profile and dimensions for external spline (shaft) and internal spline (hub). Drawing information and modification index is entered in WN8.
