The common coupling can be bent at any attitude (rotation perspective forty five degrees), and it is going to substitute the transmission route at any angle.Originally, a motor shaft faces south, and the course of the rotating shaft would be changed to stand the floor through universal coupling connection.It can isolate or take in axial vibration and impact.It has broad torque, small transmission inertia, huge adjustment angle, convenient installation, large software range, lengthy carrier life, etc.It is acceptable for various occasions of overall machinery.
