How to Choose the Right Coupling?

Advantages of Shaft Coupling • Transfer the power from one end to another end • Provide connectivity of shaft with the other units that are manufactured such as motor and generators • Provide shaft misalignment and mechanical flexibility • Decreases the shock load transmission from shaft one end to another • Provide protection against overload • Adjust the rotating unit vibration characteristics • Connect the driving par

Flexible Jaw Coupling


Advantage

Works stably and reliably, with good vibration reduction, buffering and electrical insulation properties.
It has large axial, radial and angular compensation capabilities, simple structure, easy installation, and is suitable for axial and radial installation.
It has good damping and vibration reduction characteristics, which can absorb some oscillation energy, reduce the oscillation amplitude when passing the vibration point, and reduce the torsional vibration stress of the shaft segment.
It has small radial size, light weight and small moment of inertia, and is suitable for medium and high-speed applications.
Special polyurethane elastic components have high wear resistance and oil resistance, large load-bearing capacity, long service life, safety and reliability.

Application

Suitable for medium and high-speed applications, maintenance-free, and can be installed on machines that are inconvenient to disassemble. High wear and high grease working environment.


Disc Coupling

Advantage

No lubricating oil is required, the structure is compact and the strength is high.
It has a long service life and no rotation gap.
It is not affected by temperature and oil pollution, and has the characteristics of acid resistance, alkali resistance and corrosion resistance.

Application

Suitable for shaft system transmission in high temperature, high speed, corrosive and medium working conditions.

Flexible Coupling

Advantage

It is most suitable for correcting deflection angle and axial deviation, but its ability to handle eccentricity is relatively poor.
It also has the same impact on the rigidity of the coupling under torsion load. Excessive rotational clearance under torsion load will affect the accuracy of the coupling and impair its overall performance.

Application

Suitable for light load applications, suitable for correcting deflection angle and axial deviation, and avoiding eccentricity using elastic couplings.


Rigid Coupling

Advantage

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 high-speed environments.
Unable to compensate for the relative displacement between axes caused by high temperatures generated by high-speed operation.
The small-sized rigid coupling has the superior performance of light weight, ultra-low inertia and high sensitivity.

Application

If the concentricity of the shaft is high or the control is better, rigid couplings can perform very well in servo system applications. Super oil-resistant and corrosion-resistant, suitable for oily or corrosive environments.
