Software for Parallel Key Joints

(C) Copyright 1994-2024 by HEXAGON Software, Berlin

WN3 software calculates the load-bearing capacity of a parallel key joint in accordance with DIN 6892. The dimensions for the parallel key in accordance with DIN 6885 and ANSI B17.1, as well as material values for sliding key, shaft and hub can easily be taken from the integrated data base. The complete printout, table and drawings of the parallel key, shaft groove and hub groove can be printed out.

Calculation

In pre-dimensioning the shaft diameter can be calculated from nominal torque, yield point of the shaft and hub material and application factor and, then an appropriate sliding key can be selected from the data base. In recalculation, in accordance with DIN 6892, the following are taken into account: maximum torque, load distribution factor, friction factor (for press fits), additional bending moment, alternating load factor and load peak frequency factor. The application factor and hardness influence factor for shaft, hub and sliding key are automatically selected from material database by WN3. Safety margins against breakage due to maximum and equivalent torque for sliding key, shaft and hub are calculated.

Parallel Key Data Base

WN3's scope of delivery includes a data base containing all parallel key dimensions in accordance with DIN 6885 (pages 1, 2 and 3) and ANSI B17.1. The data base file may be modified and extended by the user.

Material Data Base

The material for shaft, hub and parallel key can be selected from a data base with nearly 1000 material entries.

Printout

The calculation results can be displayed on screen, printed on any Windows printer, saved as TXT or HTML file, or loaded in an Excel worksheet.

Units

WN3 can be switched between metric and imperial units.

CAD Interface

A true-scale drawing of the sliding key as well as section drawings of the shaft and hub with the appropriate key groove can be exported directly to CAD via the DXF or IGES interfaces, as well as a drawing table with the most important data.

HEXAGON Help System

For each input you can have a help text and auxiliary picture displayed. When limiting values are exceeded the program will display warnings and error messages. You can then view the error description with remedy suggestion in the Error-Info Window.
