A rigid coupling is a torsionally rigid coupling that has no rotational clearance even when under load. Even when there is a deviation that generates a load, the rigid coupling still transmits torque rigidly.
If there is any deviation in the system, it will cause premature damage to the shaft, bearing or coupling, which means that it cannot be used in a high-speed environment because it cannot compensate for the relative displacement between the shafts caused by the high temperature generated by high-speed operation.
Of course, if the relative displacement can be successfully controlled, the rigid coupling can also perform very well in servo system applications.
In particular, small-sized rigid couplings have the advantages of light weight, ultra-low inertia and high sensitivity, and in practical applications, rigid couplings have the advantages of maintenance-free, super oil resistance and corrosion resistance.
Due to its high torque bearing capacity, rigidity and zero clearance performance, small-sized aluminum alloy rigid couplings are increasingly used in the field of motion control.
