The analysis of safety clutches shows that, despite the high rates of scientific and technical progress in the field of mechanical engineering, the development of safety clutch designs is noticeably lagging behind, and their technical and operational characteristics in general do not fully comply with modern requirements for the protection of machine drives. Friction clutches have a high response accuracy, but at present they do not provide the necessary level of protection against overloads. For a certain period of time, these performance characteristics met the necessary requirements for accuracy of operation. However, due to the steady increase in the technical characteristics of machines and mechanisms at present, some technological equipment requires the implementation of technological processes to preserve existing power factors with minimal (up to 7 … 10%) deviation of the nominal values. Such equipment may include, for example, forging and stamping equipment. To ensure a high degree of constancy of the working forces and moments in the drives of the specified equipment, the use of safety couplings with a significantly higher accuracy of operation within the above limits is required.
