Abstract: In the modern mining industry, quite complex tasks have been formed, aimed, on the one hand, at increasing the productivity of mining complexes, and on the other hand, at resource conservation in the production process. Crushing equipment operates under high dynamic loads, actively wearing out not only the elements of the mechanism directly involved in crushing, but also the drive elements of the mechanism: shafts, transmission mechanisms, etc. Sudden equipment failures associated with fatigue failures and wear lead to downtime and reduced productivity, and a solution aimed at increasing the power and geometric dimensions of the equipment does not meet the modern direction of resource and energy conservation. Therefore, the development and research of safety elastic-damping devices that reduce the impact of dynamic loads and protect crushing equipment elements from high-amplitude dynamic loads and overloads is a relevant direction in the mining industry. A new hydromechanical device with a toothed differential mechanism has been developed and studied. It has the functions of damping dynamic and impact loads and protecting against sudden overloads of cone crusher elements. Theoretical and experimental studies have shown that the proposed device reduces dynamic loads and protects against overloads, most often associated with the ingress of an uncrushed body into the crushing chamber, much more effectively than known elastic couplings and safety devices. The constructed dependencies allow us to determine the parameters of the safety device, in which the impact of dynamic loads will be minimal. A disadvantage of the new design of the safety device was revealed during experimental studies. A new design of a combined safety device has been developed, in which this disadvantage is eliminated.
