Elastic sleeve pin coupling

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 elastic sleeve pin coupling was once 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 was the first in my country. Standard coupling.Get more news about Elastic Sleeve Pin Coupling Factory,you can vist our website!

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 offset 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.

Main features of elastic sleeve pin coupling

It is composed of two half couplings, pin, retaining ring and elastic sleeve.The elastic sleeve is sleeved in the pin, and the tapered end of the pin is inserted into the taper hole of the half coupling and fixed with a nut.The other end of the pin with the elastic sleeve is inserted into the round hole of the flange of the half coupling.Relying on the gap between the elastic sleeve and the round hole on the flange of the half coupling and the deformation of the elastic sleeve, the coupling can have a certain degree of compensation for the relative deviation of the two shafts and general vibration reduction performance.The outer surface of the elastic sleeve is provided with a trapezoidal ring groove. The standard stipulates that the drum-shaped elastic sleeve can also be selected according to the needs.

Structural performance

Due to the gap between the elastic sleeve and the round hole on the flange of the half coupling and the deformation of the elastic sleeve, the coupling has a certain degree of compensation for the relative offset and shock absorption performance.
