THE COMPARATIVE ANALYSIS OF COMPUTER MODEL OPERATION OF TOOTH GEARING WITH EVOLVENT GEARING AND NOVIKOV’S GEARING

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.
