Specification of displacements/deviations
| Symbol | - |

| Unit | - |
| Attribute-ID | use existing deviations |
| Numeric ID | 2338 |
| Value Type | PMBoolean |
If selected, the tooth contact simulation in the extended gearing calculation is performed with consideration of:
- Any existing or calculated flank deviations due to overlapping with the nominal flank geometry,
- Any existing or calculated load-dependent relative position deviations as well as installation dimension deviations from corresponding changes in the nominal installation position,
- Any pitch deviations due to changes in the torsion angle.
| Deviation | Gleason | Klingelnberg | |
| Deviation of the offset | fav | E | V |
| Axial displacement of the pinion | fs1 | P | H |
| Axial displacement of the crown wheel | fs2 | G | J |
| Deviation of the shaft angle | fΣ | Σ | Σ |
Note: The deviation of the offset follows the convention of the positive and negative center distance, and thus is dependent on the spiral angle of the crown wheel. The Klingelnberg convention differs from the Gleason convention in that it is independent of the spiral angle of the crown wheel. The increase of the center distance shown in the figure above corresponds to a positive deviation of the offset V. Displacement in the opposite direction corresponds to a negative deviation of the axis displacement V.
