What is the role of fluid coupling

1 , easing gear shaft rotation against accidents ;2 , the compensation and resettlement due to manufacturing defects caused by coupling two axial displacement , radial displacement and angular displacement restraint shaft produce excessive additional load ; Hydraulic tube fittings 3 the axis of rotation to reduce vibrations. In addition , it is only accepted with greater resistance to the structure or external resistance of the material within the larger ( such as rubber , plastic, etc. ) to make the center of the coupling member when the force transmission can be achieved .4 When stiff by unexpected overload, usually cause the drive device or other parts of the ground . If accepted by coupling the drive shaft lines , using the contact sleeve is breaking the coupling elements , evacuation or slipping, so that the force transmission stream flow restraint or limited force to convey , you can play a protective effect .
