Our company has delivered the clamshell coupling to overseas customers. When assembling and disassembling the clamshell coupling, the shaft does not need to move axially, so the assembly and disassembly are very convenient. The disadvantage of the clamshell coupling is that the alignment accuracy of the two shaft axes is low, the structure and shape are relatively complex, and the manufacturing and balance accuracy are low. It is only suitable for low-speed and stable load situations. Usually, the maximum outer edge linear speed is not more than 5m/s. When the linear speed exceeds 5m/s, balance verification is required. The housing of the clamshell coupling has multiple blade branches. Among them, like the sliding block coupling.

The structure of the clamshell coupling has the function of buffering and vibration reduction due to its elasticity. Therefore, it is widely used in occasions with strong vibration. The performance limit temperature of the elastic body determines the usage temperature of the coupling. It has good universality, a wide application range, and is easy to promote. One of the most prominent advantages of this coupling is that it only requires suitable for the installation of axis alignment difficulties, thereby ensuring its zero-gap performance. Different from the sliding block coupling, the jaw coupling transmits through compression， while the sliding block coupling transmits through shear force.

These couplings have also undergone blackening treatment,ensuring adequate anti-corrosion function.
