Energy limitations of changes in construction of rotators

Abstract

Abstract. The paper considers the problem and its solution for the effective modification of the impulse rotators construction. When applying torsional vibrations to the working tool, the destruction of rocks occurs on the cleavage. The kinematic exciters of oscillations are able to change the amplitude-frequency characteristic, the loading pattern, the quality of processing according to the requirements of the material being processed. Constructive use of the oscillation device contains links and kinematic pairs, which quantity and quality determine additional drive energy losses. The authors estimate the expediency of drive elements installed by the magnitude of losses and the increase of effective work. The costs per output unit should not exceed the losses in the existing structure after changing the rotation drive of the working element.
