The pin coupling has the ability to compensate for the relative offset of the two shafts and reduce vibration and conflict.The elastic sleeve is a compression deformation. Because the thickness of the elastic sleeve is thin and the elastic deformation is limited, although the elastic sleeve pin coupling can repay the axis displacement and elasticity, the allowable repayment amount for the axis displacement is less and the elasticity is weak.

　　The elastic sleeve pin coupling is based on the friction moment of the contact surface due to the locking force of the pin group, and compresses the rubber elastic sleeve to transmit the torque.It is suitable for small and medium power shafting transmissions with good rigidity of the installation base, high centering degree, semi-large impact load, and low vibration reduction requirements.In the flange coupling, the screw connection belongs to the rigid connection, and the assembly requirements are high.

　　Oil-resistant rubber is often used in the form of a pupa to increase its elasticity.The pin coupling uses a pin with an elastic sleeve (rubber material) at one end and is installed in the flange hole of the two halves of the coupling to successfully connect the two halves of the coupling.It is convenient to change the elastic sleeve without moving the half coupling.
