In a certain period of time, when the torque value increases above the permissible value, they disconnect the kinematic chain of the mechanism drive, thus preventing breakage of critical machine components. Accordingly, the use of safety devices in machine and mechanism drives is essential for modern engineering. One of these devices is the toothed safety clutch (TSC), which is characterized by relative simplicity of design and excellent functional qualities. Currently, many designs of safety clutches are in operation, but each subsequent design is developed to increase its manufacturability, improve technological capabilities, operation accuracy and reliability, which was implemented in the proposed design of the safety clutch.
