LT elastic sleeve pin coupling

LT elastic sleeve pin couplingIt is a flexible coupling with a non-metallic elastic element. Its structure is very similar to that of a flange coupling, but the two half couplings are connected without bolts and use pins with rubber or leather sleeves to realize the two half couplings. The coupling of the shaft section.The elastic sleeve pin coupling was once a 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 is a national standard.In order to replace the pin sleeve 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.

LT elastic sleevePin couplingThe structure is relatively simple, easy to manufacture, does not require lubrication, does not need to be bonded with metal vulcanization, it is convenient to change the elastic sleeve, does not need to move the half coupling, and has the properties of compensating for the relative deviation of the two shafts and damping and buffering.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, the elastic pin sleeve coupling can compensate the axis displacement and elasticity, but 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.
