● Elastic sleeve pin coupling is the use of one end with a flexible sleeve (rubber material) of the pin, mounted in the half of the coupling flange hole, in order to achieve the coupling of the two halves. Elastic sleeve pin coupling was once the most widely used coupling in China, as early as the late 1950s that has been developed for the mechanical department standard, JB08 - 60 elastic ring pin coupling, is China 's first ministry Standard coupling.

Flexible sleeve pin coupling structure is relatively simple, easy to manufacture, no lubrication, no need to bond with the metal vulcanization, easy to replace the elastic sleeve, do not move the semi-coupling, with a certain compensation for two-axis relative offset and vibration damping performance The Elastic sleeve work is subject to compression deformation, because the elastic sleeve thickness is thin, small size, elastic deformation is limited, so the elastic sleeve pin coupling can compensate for axial displacement and elasticity, but the axis displacement allowable less compensation, Flexibility is weak. The elastic sleeve pin coupling is the friction torque generated by the locking force of the pin set and the rubber elastic sleeve to transmit the torque. Applicable to the installation of a good rigidity, high precision, the impact load is not large, low vibration requirements of the small and medium power shaft drive.

LT type (the original TL type) elastic sleeve pin coupling basic performance parameters and the main size

• Pure shear rubber coupling
• JMIJ type diaphragm coupling
