The characteristic of elastic sleeve pin couplings is simple structure, easy to install, easy to replace, small size and light weight. Work due to elastic sleeve squeeze occurs when the deformation is small, and the elastic sleeve and the fitting clearance of pin hole shoulds not be too big, so elastic dowel pin shaft coupling buffer and damping is not high, compensate the relative displacement between the two axis is smaller.

application

It is widely used in the shock load, which is rigid by the motor drive base, and in the various small and medium power transmission shafts.

Deficiency in

Column (1) due to the elastic sleeve pin coupling with material of cast iron, its weight is 38.8 kg, make the motor in the process of water supply operating waste a lot of energy, has affected the unit efficiency, increase the operation cost.

(2) because it is very troublesome to disassemble the shaft of the elastic shaft pin, it is easy to deform or damage the cast iron coupling when servicing the pump and motor.

(3) it is difficult to find the two axis relative radial displacement, which is 0.2 ~ 0.6 mm, which is very difficult to find the coupling of the coupling. In addition, the vibration and noise of the pump unit are increased due to loose bolts during operation.
