FIELD: mechanical engineering. SUBSTANCE: proposed spur gearing includes driven and driving gear wheels. Salient feature of given gearing lies in that diameters of vertexes of teeth depend on condition of provision of coefficient of end face overlapping lying within limits from 1.03 to 1.2 included. EFFECT: reduced usage of metal, higher efficiency and lesser consumption of energy in process of gear cutting. 3 dwg, 1 tbl
