The article presents the design of a finger safety clutch with axial withdrawal of a jammed screw to remove it from the overload zone. The theoretical dependences of determining the change in torque during the operation of the finger safety clutch on the angle of relative rotation of the half couplings and the design and technological parameters of the engagement elements are presented. On the basis of force and kinetostatic analysis of the coupling, the nature and magnitude of the change in their torque at all stages of relative rotation of the coupling halves were determined. The developed and manufactured prototypes of the finger safety coupling made it possible to conduct a set of experimental studies. For the safety clutch of a screw conveyor, based on the analysis of theoretical and experimental test data, the adequacy of theoretical calculations and actual values of torques during the mechanism operation was compared.
