Increasing the durability methods of the drilling string lock connection

Abstract

An integrated approach to the technological preparation of production ensures the accuracy and quality of the surface layer of highly loaded parts, which increases the value of fatigue resistance, as well as forms compressive stresses. Analysis of the data obtained during the research showed that compressive residual stresses in the surface layer were formed by applying finishing operations. Increasing the fatigue resistance of the hardened surface leads to an increase in the durability of mechanical engineering products. At the same time, attention should be paid to the study of the surface accuracy and quality based on the technological process improvement.
