Features of elastic coupling

Elastic pin tooth typeCouplingIt has the ability to compensate the relative deviation of the two shafts to a certain extent. It is suitable for medium and high power transmission, and is not suitable for working parts that have certain requirements for vibration reduction and strict noise control.
　　The elastic pin gear coupling is a pin made of several non-metallic materials, which is placed in the mating hole between the two halves of the coupling and the inner surface of the outer ring, and the two halves are connected through the pin to transmit torque. Shaft coupling, the elastic pin gear coupling produced by Beijing Cheng Coupling Factory has the following characteristics: (1) The transmission torque is large, and the rotation diameter is mostly smaller than the gear coupling at the same torque. Small in size and light in weight, it can partially replace gear couplings. (2) Compared with the gear coupling, the elastic pin gear coupling has a simple structure, fewer components, and is more convenient to manufacture. It does not require a gear processing machine tool. (3) Convenient maintenance and long service life. The nylon pin can be replaced by removing the baffle plate.
　　The characteristics of the elastic sleeve pin coupling are:
　　XNUMX. 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.
　　XNUMX. 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 relatively large. Less, weaker elasticity.
　　 XNUMX. The structure of the elastic sleeve pin coupling is relatively simple, 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 a certain compensation for the relative deviation of the two shafts and damping Buffer performance.
