Introduction to the characteristics of elastic sleeve pin coupling

The elastic sleeve pin coupling is composed of two half couplings with the same structure. The difference between the two is only in the assembly size of the shaft. The two half couplings are connected by a pin with an elastic element. The torsional shock absorber of the device is a ring sleeve, which is connected and centered in the end disc. An intermediate ring is installed between the elastic elements on the pin. The ring sleeve floats and is used for the end discs that are aligned with each other. The pins are connected, and the two halves of the coupling are held along the ends.When the coupling rotates, the disc and the ring sleeve rotate together and are concentric with the half coupling under the action of centrifugal force. The floating end disc with the ring sleeve, pin and elastic element is a free inertial mass—torque Shock absorber, for this type of shock absorber, the excitation will be consumed on the deformation of the elastic element, because the rubber produces a large deformation and has a large internal friction, so it can dissipate a lot of energy.Torque is transmitted from one half coupling through the elastic element mounted on the pin to the other half coupling. The pin and half coupling are non-rigidly connected to make the pin load smoothly and reduce the lateral force at the same time .In addition, the pin is not in a cantilever relationship, but the end is fixed on the end disc.
