The elastic log-off coupling has a relatively 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, and has the properties of compensating for the relative offset of the two shafts and damping.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 pin sleeve 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 high-speed, low- and medium-power water pumps with high rigidity of the mounting base, high centering accuracy, low impact load, and low vibration reduction requirements.

 The elastic log-off coupling has the following characteristics:

●(1) The transmission torque is large. At the same torque, the rotation diameter is mostly smaller than that of the gear coupling, with small volume and light weight, which can partially replace the gear coupling.

●(2) Compared with gear couplings, it has simple structure, fewer components, and is more convenient to manufacture. It does not require gear processing machine tools.

●(3) Easy maintenance and long service life. The nylon pin can be replaced by removing the baffle plate.

●(4) The nylon pin is a self-lubricating material and does not need lubrication, which not only saves lubricating oil, but also purifies the working environment.

●(5) Poor vibration reduction performance and high noise.
