4. Conclusions 1. The paper proposes a method for calculating the torque transmitted by the developed TSC design and examines the strength of its most critical elements based on load modelling in the form of nominal torque using a CAD model. 2. As a result of theoretical studies of the equilibrium condition of the contact pair, expressions were obtained for calculating the maximum torque, force transmission coefficient, and spring compression value. These expressions can be used in practice when designing similar devices. 3. Strength testing of the most critical components showed that for nominal loads up to М мах = 1000 N∙m, it is sufficient to use inexpensive structural materials (steel 20), but since modern TSC designs are used in machine drives to transmit nominal torques of up to 8000- 9000 N∙m, it is advisable to use steel grades 45…55 or perform technological strengthening operations (hardening, cementation, nitriding) on the working surfaces of the coupling to ensure the strength and reliability of the device.
