“…Gradual accumulation of the energy leads to occurrence of shear deformation in the material, which is followed by the relaxation of residual stresses. To implement this approach, the authors developed and tested in real production conditions a technological method of treatment of a ring part by continuous running with three rolls [17][18][19].…”

This paper discusses the technological method of residual stress relaxation of bearing rings by centerless running with cylindrical rolls. Described a new approach to relieve residual stresses by centerless running of elastically-deforming rolls on the basis of the geometrical setup of the equipment. It was found that geometrical setup of the equipment influences an elastic strain of parts and the degree of residual stress relaxation. We obtained a mathematical model for calculation of setup parameters to ensure the required variation value of elastic strain of the part. The results of experiments confirm the influence of the geometric setup on the magnitude of residual stress relaxation.

“…Previously developed technology [9][10][11] is based on using the energy of ultrasonic vibrations and confirms the arguments in favor of vibromechanical relaxation of residual stresses. However, vibromechanical relaxation of residual stresses in bearing rings can be done without the use of ultrasound, providing cyclic elastic strain of the rings through a multi-cycle running [12][13][14].…”

The paper provides the comparison of vibromechanical technology for stabilization of bearing rings and thermal tempering on the following parameters: performance, energy consumption, and magnitude of residual stresses after treatment. To assess the effectiveness of residual stress relaxation through the usage of vibromechanical energy, there were conducted experimental studies on a specially designed and manufactured prototype of the equipment. The results of experimental studies show that the energy consumption during vibromechanical stabilization is ten times less, and performance is several times higher than during the thermal tempering. Moreover, vibromechanical stabilization allows more effective residual stresses relaxation. The costs for capital investment can be reduced, as the cost of equipment for vibromechanical stabilization is ten times less than the cost of electric furnaces.
