[0002] In the heavy-load industry, couplings generally use drum gear couplings or cross universal couplings. The drum gear coupling is characterized by large torque bearing capacity, but the allowable swing angle generally does not exceed 2°, and the torque to mass ratio is low, and the cost is high; the cross universal coupling is more commonly used in the heavy-load field, and its characteristic can meet the swing angle of 10°~15°; the compensation ability is stronger than the drum gear coupling; but affected by the structure of the cross package itself, stress concentration cannot be avoided at the root of the cross, and affected by the large-sized cross package and low machining accuracy, the upper limit of the cross universal bearing capacity is 20~30MNm; considering the characteristics of the drum gear coupling and the cross universal shaft, they cannot meet the characteristics of large torque and large swing angle, especially in the wind power testing industry, the design and selection of couplings with large torque and large swing angle greatly troubles the whole machine testing.
