WN11 Software calculates load bearing capacity of Woodruff key joints according to DIN 6892. This standard is specified for parallel keys, but can also be used for Woodruff keys, if load-bearing length and load-bearing height are replaced by load-bearing areas of shaft groove, hub groove and Woodruff key.

Dimensions of the Woodruff key according to DIN 6888 as well as material properties for Woodruff key, shaft and hub can be loaded from the integrated database. As a result, WN11 generates printout, tables and drawings of Woodruff key, shaft and hub.

In Pre-Dimensioning, you can calculate shaft diameter from torque and material data, then select suitable Woodruff key from database.

For recalculation according to DIN 6892, additionally enter peak torque Tmax, load distribution factor, friction factor (for press fits), additional bending moment, load alternating factor and load peak frequency factors. Support factors fS and hardness factors fH are loaded from material database. WN11 calculates safety margins against permissible pressure by maximum and equivalent torque on Woodruff key, shaft and hub.

WN11 includes a database with dimensions of Woodruff keys according to DIN 6888. Database may be extended and modified by the user.

Material properties for shaft, hub and Woodruff key may be selected from material database.

Calculation results may be printed on screen, printer, text file, or exported into an Excel worksheet.

A true-scale drawing of the Woodruff key and profile drawings of shaft groove and hub groove can be exported to CAD via DXF or IGES interface.
