What are the connection methods of universal coupling?

Universal coupling is to use high-strength bolts and self-locking nuts to connect the flanges at both ends to other mechanical components, its moment is transmitted through the flange end keys and friction between the flanges to transfer. SWP type connection dimensions and bolt pre-tightening torque according to the provisions of Figure 3 and Table 3; SWC type connection dimensions and bolt pre-tightening torque shall be specified in Figure 4 and Table 4. Bolts can only be placed from the flange side matching with the coupling, and the nut is tightened from the flange side of the universal coupling. The mechanical properties of the bolts meet the requirements of GB3098.1, grade 10.9, and the mechanical properties of the nuts should meet the requirements of GB3098.4, grade 10. You can link the coupling well.
