Couplings
The universal coupling can be bent at any angle (rotation angle 45 degrees), and it can change the transmission direction at any angle.
Originally, a motor shaft faces south, and the direction of the rotating shaft can be changed to face the ground through universal coupling connection.
It can isolate or absorb axial vibration and impact.It has large , small transmission inertia, large adjustment angle, convenient installation, wide application range, long service life, etc.
It is suitable for various occasions of general machinery.
