Calculation of virtual equivalent cylindrical gear pair
The virtual equivalent gear set is calculated following the calculation of the basic geometry.
Materials for Gears
The application provides a dialog box for management of materials for gears. According the standard ISO 6336-5
the contact stress limit value and bending stress limit value are to determine in function of the tooth flank hardness using the
equation of a straight line σH,F = Ax + B where x stands for the flank hardness, A is the slope coefficient and B
is the segment on y-axis. This three parameters are derived 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 σHlim and the bending stress limit value σFlim
are determined in function of the tooth flank hardness.
Calculation of Load Capacity according Standard ISO 10300-2,3
Input operating conditions as shown in dialog box:
Input of gear teeth finish, effective face width ratio, tooth form corrections and imposed minimum value for safety factors.
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
SH1,2 and
tooth root bending stress
SF1,2 are calculated and compared with the respectively imposed minimal values.
The application warns with a messagebox if minimal safety values are not satisfied.

Torque Rating of Bevel Gear Pair
The application supports also the torque rating of a given bevel gear pair with the selected gear
materials and given operating conditions by an iterative load capacacity calculation process.
