The object of the study is an electromechanical hammer drill with a rotary-impact mechanism. When studying the dynamics of an electromechanical hammer drill with a rotary-impact mechanism, methods of mathematical modeling and comparative analysis were used. A calculation scheme has been developed and, on its basis, the equations of motion of mechanical transmission elements and working tools of an electromechanical hammer drill with a rotating impact mechanism have been obtained. The solution of the resulting equations is carried out using the Runge-Kutta numerical method using the Mathcad computer program. When analyzing the dynamics of the elements of a rotary hammer with an impact-rotating mechanism, the value of the moment of resistance on the part of the rotating mechanism is taken as a variable parameter, since during the operation of the rotary hammer, with increasing drilling depth, the magnitude of the moment acting on the part of the tool increases. The dependences of the angular velocities of the elements of the hammer drill are given, which make it possible to select rational design parameters of the links of the electromechanical hammer drill using an impact-rotary mechanism.
