Abstract

A description of a new design of a vibrating machine for strengthening the surface plastic deformation of cylindrical long parts, in particular stabilizers of wheeled carriages of railway cars, is given. The main design and technological parameters of the process of vibration – centrifugal strengthening of these parts are outlined. The influence of technological parameters of this hardening process on such basic indicator of hardening processing as depth of hardening is experimentally investigated on cylindrical samples from 45 steel. Mathematical dependences for the choice of optimal values of design and technological parameters of this hardening treatment are given.

The list of long cylindrical parts for which vibration – centrifugal strengthening treatment is suitable and effective is outlined, among which torsion shafts of suspension of military tanks, axles of wheels of railway transport, drilling and casing pipes of gas and oil wells.
