Technology of Residual Stresses Relaxation by the Ultrasonic Vibrations
The paper studies the effectiveness of new techniques of stabilizing the geometrical parameters of bearing rings in comparison with the thermal stabilization. Processing of bearing rings is made on a special machine in a liquid medium where the ultrasonic vibrations are excited. It is shown that roundness of the rings after ultrasonic stabilization is substantially lower than after the heat treatment.
