FEATURES OF GEARING OF DRIVES OF NOVIKOV

Abstract

The evolvent gearing widespread in modern mechanical engineering is linear as contact piece of teeths happens on the line (practically on a narrow platform) located along a cog (fig. 1.1.a) and has hypersensibility to sidesways. This shortcoming can be reduced at pointed contact piece. Mikhail Leontyevich Novikov (1915 — 1957) offered pointed gearing in which cross-sections of teeths of wheels in face (cross) section are outlined on arches of a circle (fig. 1.1.b). The cog of a pinion gear is carried out convex, and a wheel cog — concave that increases their specified curvature radius, increasing thereby contact strength of drive.
