Abstract:
In the article settlement sizes of the maximum contact tension by techniques of various authors
taking into account solutions of Hertz are specified, researches on comparison of load ability of elements of the gears
with evolvent gearing applied in the drives of ball mills and gears with Novikov's gearing are considered. The
numerical finite element models (FEM), calculated tooth gearing and boundary conditions and also calculation the
stress-strain state of FEM by means of the programs MSC/Patran, MSC/Nastran are developed.
As a result of research the load ability of Novikov's gearing from conditions of contact endurance of active
surfaces of teeths which is higher, than for gears with evolvent gearing, with the same overall dimensions, owing to
the big specified radius of curvature of the contacting teeths is established.
