A qualitatively new principle of motion transmission is presented in the book, where the power at the output (executive) organ of the machine significantly exceeds the input power while maintaining the input motion velocity. Here the reproduction of the initial kinematics is carried out directly, without a signal control system in this self-adjusting mechanism.Several amplification mechanisms have been developed and tested. Each includes only three functional elements - a control (input) link, a controlled (output) link and a servo motor as the energy source.The mechanical transistor action...
