A SPECIAL DEVICE FOR THE IMPLEMENTATION OF THE TECHNOLOGICAL PROCESS OFBALL-ROD HARDENING OF WELDED JOINTS OF STRUCTURES THAT ARE ROUND RODS
The results of experimental studies of noise and vibration during ball-rod hardening are presented. Taking into account that the technological process of the local SHSU is intensively used in various branches of mechanical engineering, it seems advisable to perform acoustic calculation and design a special stand for a wide range of configurations, diametrical dimensions of parts of the type of rotation bodies, which allows to achieve compliance with sanitary standards. This article describes the design of a special stand. The calculation scheme for determining the required sound insulation of the sound protection system of the stand is presented. Dependences for calculating noise levels in the workplace are obtained. Taking into account the implementation of sanitary noise standards, the required sound insulation of the noise protection system is determined.
