ECONOMIC EFFICIENCY OF ROLLING GEAR-SHAPING CUTTERS OF ASSEMBLY CONSTRUCTION- BASIC PROVISIONS AND ASSESSMENT

Abstract

Technical backgrounds and reasons of economic and social efficiency of assembly rolling gear-shaping tool are given. It is considered development of methodological procedure of aggregative generalized calculation of its economic efficiency. Structure of calculation is specific predetermined by alteration of design conception from monolithic to assembly for nonadmission of profiling distortion after regrindings of tool. Development is motivated by technical ideology of improved gearwheels with constant normal pitch whose production needs in sufficient tooling backup. The first part is devoted to the main provisions of economic efficiency.

Keywords
