| The models of toothed gearings to fit the
gearbox, which is installed in the harvesters produced by PG GOMSELMASH, were
developed. The complex of tests was performed with the results listed below.
Model of toothed gearing (a) and its
modification (b)
Test results of the models of
toothed gearings made of steel 18ХГТ:
FG
– the limiting load according to
the criterion of mechanical fatigue;
FR
– the limiting load according
to the criterion of rolling fatigue

Steel 25ХГТ:
statistical correlations of rolling fatigue limits ρf, fatigue
limits under bending σ-1
and hardness HRC, used as the basis of statistical quality control of gear-wheel
providing risk application ρ<[
ρ]=
