The GY flange coupling has a simple structure and is easy to use. It can transmit large torque, but it cannot cushion and absorb vibration.It divides the two half couplings with flanges with ordinary flat keys
The JQ type-clamping shell coupling uses two axially split shells, which are clamped by bolts to realize the connection of the two shafts. The torque is transmitted by the friction between the two halves of the coupling surface.
YL flange coupling does not have radial, axial and angular compensation performance. If the centering accuracy of the connected two shafts cannot be guaranteed during use, the use of the coupling will be reduced.
