Materials for Gears
The application provides a dialog box for management of materials for gears. According the standard ISO 63365
the contact stress limit and bending stress limit are to determine in function of the tooth flank hardness using the
equation of straight line σ_{H,F} = Ax + B where x stands for the hardness, A is the slope coefficient and B
is the segment on yaxis. This three parameters are token from the standard. Input for a gear pair requires input of material
separately for pinion and gear, the material quality grade and the hardness of tooth flank. With the equation of the straight line
the contact stress limit value σ_{Hlim} and the bending stress limit value σ_{Flim}
are determined in function of the tooth flank hardness.
Gear Forces
Input of the coordinates of gear supports A and B and mesh point X. A cylindrical coordinate system is being used. The application
calculates the gear forces as transverse tangential force F_{t}, transverse radial force F_{r}
and the axial force F_{a}. The reaction forces in the supports are calculated.
Dynamic Model
The application provides for a powerfull modeller for the calculation of polar mass inertia moments for pinion and gear even in the
dimensioning stage.
The mass of a third gear such as an intermediate gear or as a gear rigidly connected to a pinion shaft can be taken into account.
The polar mass inertia moments are reduced to a single mass per unit of facewidth acting along the contact line.
The spring constant is determined with the single pair stiffness c' and the mean mesh stiffness per unit face width
c_{γ} as described in the standard ISO 63361. The application calculates the natural frequency of
the massspring system and determines to which domain the speed of the gear pair wil belong. If the speed is in critical domain,
the application will indicate which measures can be taken to remediate the problem.
Load Capacity according standard ISO 63362,3
The application determines the influence factors, the contact  and bending stresses, the permissible stresses for contact
and root stress for the choosen gear materials. The safety factors for contact stress S_{H1,2} and
tooth root bending stress S_{F1,2} are calculated and compared with the respectively imposed minimum values.
The application warns with a messagebox if the imposed min safety factors are not satisfied.
