WN10 software calculates dimensions and strength of a toothed shaft joint with involute flanks to DIN 5482 (Release 1950). Another application for WN10 is the calculation of self-defined non-standard splines: you can directly enter tooth tip diameters and tooth root diameters of external and internal spline,and WN10 calculates tooth height coefficients.
The module allows a fast and easy calculation of the geometry and strength of involute splines according to DIN 5480 (03/2006), DIN 5482 (03/1973), ISO 4156 (10/2005), ANSI B92.2M-1980 (R1989) and ANSI B92.1-1996. The geometry can be selected conveniently from a data base. The profile search function can help the user to quickly identify a profile. An own input of involute spline geometry is also possible.

In order to determine the tolerances, the gear accuracy and backlash allowance sequence according to DIN 5480, DIN 5482, ANSI B92.2 and ANSI B92.1 can be selected from listboxes. This will determine the permissible deviations and tooth thickness allowances. The calculation of the tooth thickness allowances can be done based on measured values or given test dimensions. Test dimensions, backlash normal plane and backlash pitch diameter are calculated as well. For the test dimensions, the required number of the teeth for span measurement and the diameter of ball or pin will be determined automatically by the program or can be entered by the user.
The DIN 5480 and DIN 5482 series of standards is limited to splines with a pressure angle of 30, since pressure angles of 37.5 and 45 are covered by ISO 4156
