The work is devoted to the problem of protection of mechanical transmissions of transport and transport-technological machines from torque overload. The urgency of this problem and the currently proposed ways of solving it are shown. The problem of protecting propeller shafts in the sea and river fleets is especially urgent. Breakage of the ship shafting elements can create an emergency and immobilize the ship for a long time. From the review of the literature, it was concluded that no new solutions to this problem have been proposed recently. The paper proposes an original design of a safety coupling, which allows to reliably protect the transmission from torque overloads. The offered coupling is simple and technologically advanced. It does not require the use of expensive materials for its manufacture; it is completely made of steel. There are no elements in the coupling that collapse during overload that need to be replaced. After triggering (or overturning) the safety coupling, it can be quickly restored to its original state. The overturning moment to which the coupling is adjusted can be easily changed. The paper presents a method for calculating the main elastic element, as well as an example of calculation and selection of an elastic element of a safety coupling on the example of a ship shaft line driven by a ship diesel engine 6CHNSP 18/22. In conclusion of the work, conclusions are drawn that show the possibility and advantages of using the proposed safety coupling.
