Title:
GRADIENT LOAD UNIVERSAL COUPLING
Document Type and Number:
WIPO Patent Application WO/2017/181693
Kind Code:
A1
Abstract:
A gradient load universal coupling, structured to be: transmission between a primary connecting flange (1) and a secondary connecting flange (2) is achieved by means of a cross pin (11), transmission between the secondary connecting flange (2) and a primary shaft end flange (3) is achieved by means of a connecting bolt (8), transmission between a primary shaft (4) and a secondary shaft (6) is achieved by means of a connecting shaft (5), transmission between a secondary shaft end flange (7) and a tertiary connecting flange (9) is achieved by means of the connecting bolt (8), and transmission between the tertiary connecting flange (9) and a quaternary connecting flange (10) is achieved by means of the cross pin (11); the anti-torque coefficient of the connecting bolt (8) is not equal to that of the connecting shaft (5) nor to that of the cross pin (11). By means of adding a double protective structure involving the connecting shaft (5) and connecting bolt (8), gradient distribution is achieved in case of transmission overload; loads are subject to gradient distribution in case of overload during transmission, thereby reducing equipment damage caused by overload, and achieving the result of load release.
