| Summary: | The results of the analysis of scientific research in the field of non-assure mechanisms are presented, on the basis of which the conclusion is made about the need for further development of the theory of mechanism structures and methodological approaches to the synthesis of machines with special properties of kinematic structure, allowing to reduce energy consumption and improve technical performance. The results of experimental studies have confirmed the existence of a relationship between the magnitude of the pre-voltage of the closed kinematic circuit and the energy intensity of the grinding and pressing process. The revealed patterns make it possible to minimize energy consumption and adapt the technological machine to the properties of the processed material. Experimental studies of a gear-grinding mill on sandstone, quartz, marble samples have confirmed that with the same energy consumption, the maximum grinding efficiency (an increase in the proportion of fine particles) is achieved only in a certain loading range of a closed kinematic contour corresponding to the strength of the crushed material.
