TL type elastic sleeve pin coupling

LT type (formerly TL type) elastic sleeve pin coupling (GB4323-2002 replaces GB4323-1984)
 

　●The elastic sleeve pin coupling uses a pin with an elastic sleeve (rubber material) on one end, which is installed in the flange hole of the two halves of the coupling to realize the connection of the two halves of the coupling.The elastic sleeve pin coupling used to be the most widely used coupling in our country. It was formulated as the standard of the Ministry of Machinery in the late 20s. The JB50-08 elastic ring pin coupling is the first standard of our country. Coupling.
　　The elastic sleeve pin coupling has a relatively simple structure, easy to manufacture, does not require lubrication, does not need to be bonded with metal vulcanization, it is convenient to replace the elastic sleeve, does not need to move the half coupling, and has a certain degree of compensation for the relative deviation of the two shafts and damping and buffering 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, the elastic sleeve pin 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 small and medium-power shafting transmissions with good rigidity of the installation base, high centering accuracy, low impact load and low vibration reduction requirements.
