Abstract:

The results of the theoretical study of the dynamic system of the radial forging machine of the wedge-lever type are presented. The equivalent calculation scheme and corresponding differential equations of the dynamic system are compiled. After the transformation and solution of these equations, an expression for the elastic moment acting in the drive transmission of the radial forging machine is obtained. The analysis of the obtained expression for the elastic moment shows that the elimination of resonant modes of the dynamic system is possible by varying the natural frequency of the system or by the appropriate selection of the elastic-mass parameters of the drive parts of the radial forging machine. Based on the energy principle, a formula for calculating the mass of the flywheel of machine drive is obtained.
