WN7 calculates dimensions, tolerances, stress and safety factors for P4C Polygon Profiles
Additional or as alternative we offer WN14 for polygon profiles P4C, P3C, P2C, P5C (PnC).
Enter torque, select material and application: WN7 calculates minimum size required for a P4C shaft-hub joint.
WN7 calculates compressive stress, torsional stress, bending stress, and equivalent stress according to DIN 32712 and DIN 6892. Material, application factors and life expectation coefficients are considered by WN7.
Drawing tables with P4C profile drawing according to DIN 32712 may be printed directly, or exported to CAD via DXF-/IGES interface.
