Abstract
The analysis of existing problems arising in the process of manufacturing such complex profile parts as gears is carried out. The possible ways of simplifying the technological processes with the aim of improving the economic performance of production, as well as reducing the defect are defined. The carried out researches of influence of chemical composition of steel, its structural parameters on technological characteristics. The choice of compositions of the chemical composition of steel with the optimal ratio of physical-mechanical and technological characteristics is substantiated. The causes of deformation of parts in the process of heat treatment are established. The developed criteria for estimating this value. At the same time, the task of not only qualitative but also quantitative evaluation of such technological properties as the propensity of steels to deformation in the course of chemical-thermal treatment is solved, with the aim of introducing a single characteristic that determines the tendency of the steel to deform during hardening. Reducing the propensity of steel to deformation allowed to increase the economic performance of production by reducing the number of finishing operations.
