| Value Type | PMBoolean |
This attribute allows the user to define the supporting feather key length geometry.
If it is not selected, the supporting feather key length geometry will be calculated automatically.
- This differs than the length of the feather key only in case of form A, AB and BA, where the radius at the end(s) of the feather key are not considered to supporting length.
If it is selected, the user can define,
- the beginning of the supporting feather key length by entering the distance between the beginning of the feather key geometry and the beginning of the supporting feather key length (dtr).
- the length of the supporting feather key (ltr).
| a0 | Axial distance between load input and output points |
| a1 | Distance between hub face and load-bearing part of the feather key |
| bN | Total width of the hub |
| c | Width of the hub with diameter D2 within the load-bearing length |
| d | Shaft diameter |
| u | Beginning position of feather key geometry |
| uK | Beginning position of feather key supporting length |
| dtr | Distance between u and uK |
| lPF | Length of the feather key |
| ltr | Load bearing length of the feather key |
| D1 | Small external diameters for stepped hub |
| D2 | Large external diameter for stepped hub |
| BND1 | Width of the hub for D1 |
| BND2 | Width of the hub for D2 |
| Fu | Circumferential force |
| T | Torsional moment |
