Actual Science Problems of Modern Geomechanics for Conditions of Republic of Belarus

Abstract

The features of accuracy ensuring at the production of large case-hardened gear wheels connected with change of their dimensions conditioned with structure transforming into chrome-nickel alloy steel at the technological treatment and service. For the first time the hypothesis about deformation of mentioned steel taking into account unknown earlier structure transformation in near border volumes of metal granules was formulated and confirmed experimentally. The recommendations concerning material selection for large case hardened gear wheels are given.
