The elastic sleeve pin coupling uses a pin with an elastic sleeve (rubber material) at 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 origin of the elastic sleeve pin coupling: As early as the late 20s, it had been formulated as a standard of the Ministry of Machinery. JB50-08 elastic ring pin coupling was the first standard coupling in my country.
The characteristics of the elastic sleeve pin coupling: 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, with certain compensation for the relative deviation of the two shafts and damping Buffer performance.
The principle of the elastic sleeve pin coupling is to rely on the locking force of the pin group to generate the friction moment of the contact surface, and compress the rubber elastic sleeve to transmit the torque.
Purpose: Used to install small and medium-power shafting transmissions with good rigidity, high centering accuracy, low impact load, and low vibration reduction requirements.
The work of the elastic sleeve is compressed and deformed. 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. Weaker.
