The software distinguishes two sets of coefficients, which are adjustable thorough the ‘Coefficients’ dialog box. The dialog box includes coefficients that concern tooth root strength and contact stresses. In the first set we can change: factor of application k_a, minimal safety coefficient s_f_min, stress correction coefficient y_st and durability coefficient y_nt. Available for contact stresses: limit (minimum) safety factor s_h_min, durability factor z_nt and kinematic viscosity of the oil at 50 degrees temperature ni_50.



Coefficients’ values are also placed in the output file (in the results of calculations) and if we use the file to start new calculations, the coefficients’ values will be preserved.
