Dodge®Raptor series couplings belong to inseparable, mechanical, and torsionally flexible couplings with the possibility of compensating for the misalignment of axes. In the couplings with the Raptor-SK design, shear pins were additionally applied to protect the drive system from overload. The use of „fuses” in the coupling in the form of shear pins limits the value of the transferred torque to a set (safe) value; beyond which, it is cut off and the drive is consequently disconnected. In this work (with reference to the Raptor-SK coupling), calculations were made to select the diameter of the shear pins depending on the value of the limit torque Mgr. In order to assess the correctness of the selection of pins used in the coupling mechanism, experimental tests were carried out using a testing machine. A comparison was made between the design calculations of the shear pins and the results of research on a test bench.
