Calculation
WN5 calculates dimensions, tolerances,
dimension over/between pins, stress and life
expectation for involute splines according to ISO
4156 and ANSI B92.2M. Basically, WN5 uses
metric units. Imperial units inch, psi, lb-in, can
be configured as well. WN5 calculates the fit
types Flat Root Side Fit and Fillet Root Side
Fit . Pressure angle can be 30°, 37.5° or 45°.
Flank Clearance, Tolerances
WN5 calculates tolerances for diameters, space
width and tooth thickness according to ISO
4156 and ANSI B92.2M from Fit Class and
Spline Tolerance Class. When entering
centerline runout of internal and external spline,
WN5 calculates required effective clearance.
Measurement
WN5 calculates dimension over/between pins,
span measurement and tooth thickness. Pin
diameter and number of teeth measured may
be modified by the user.
Stress Calculation
WN5 calculates compressive stress, spline teeth
shear stress, hoop stress, bending stress, torsional
stress, and equivalent stress according to SAE
Design Guide for Involute Splines . Material,
application factors and life expectation coefficients
can be entered directly, or calulated by WN5.
Production Drawing
Drawing tables with spline dimension data according
to ANSI B92.2M or ISO 4156 together with a spline
draft may be printed or loaded with CAD via DXF-/
IGES interface.
Tooth drawing
WN5 generates true-scale drawings of internal and
external involute spline as DXF/IGES files for CAD
Import.
System Requirements
WN5 is available as 32-bit app or as 64-bit app for
Windows 7, 8, Windows 10.
Scope of Delivery

applications and help images, non-expiring license
for unlimited time use with update rights.
Software Maintenance
HEXAGON Software is continuously improved and
updated. Registered users are regularly kept informed
of updates and new editions.
