A detailed description

The elastic sleeve pin coupling is a non-metallic elastic element flexible coupling, and its structure is very similar to the flange coupling, but the connection of the two half couplings does not require bolts but uses a column with rubber or leather sleeves. Pin to realize the connection of the two halves of the coupling.The elastic sleeve pin coupling was once the most widely used water pump coupling in my country. It was formulated as a standard of the Ministry of Machinery in the late 20s. The JB50-08 elastic sleeve pin coupling was the first in my country Ministry standards.In order to replace the pin sleeve easily without dismantling the machine, pay attention to the distance A in the design; in order to compensate the axial displacement, pay attention to the gap c of the response size during installation.

The LT (formerly TL type) elastic sleeve pin coupling has a relatively simple structure, easy to manufacture, no lubrication, no need to bond with metal vulcanization, easy to replace the elastic sleeve, no need to move the half coupling, and has a certain compensation for the relative deviation of the two shafts. Shift and damping buffer performance.The elastic sleeve works by compression and deformation. Because the thickness of the elastic sleeve is thin, the volume is small, and the elastic deformation is limited, although the elastic pin sleeve coupling can compensate the axis displacement and elasticity, the allowable compensation amount for the axis displacement is less. The elasticity is weak.The elastic sleeve pin coupling relies on the locking force of the pin group to generate the frictional moment on the contact surface, and compress the rubber elastic sleeve to transmit the torque.It is suitable for high-speed, low- and medium-power water pumps with high rigidity, high centering accuracy, low impact load, and low vibration reduction requirements.
