elastic sleeve pin coupling


   The elastic sleeve column pin coupling uses a column pin with an elastic sleeve (rubber material) at one end, and is installed in the flange holes of the two coupling halves to realize the coupling of the two coupling halves. The elastic sleeve pin coupling was once the most widely used coupling in China. As early as the late 1950s, it was formulated as the standard of the Ministry of Machinery: JB/T 108-60 elastic ring column pin coupling is China. The first standard coupling.

   The elastic sleeve pin coupling is characterized by simple structure, easy installation, easy replacement, small size and light weight. Since the deformation amount of the elastic sleeve when it is squeezed during operation is not large, and the cooperation gap between the elastic sleeve and the pin hole should not be too large, the cushioning and shock absorption of the elastic pin coupling is not high, and the compensation between the two shafts is compensated. The relative displacement is small.


   application

   It is widely used in various small and medium power transmission shaft systems with small impact load, good rigidity driven by the motor, and accurate centering.


   Deficiencies
(1) Because the material of the elastic sleeve pin coupling is cast iron, the motor wastes a lot of electric energy during the water supply operation, which affects the efficiency of the unit and increases the operating cost.
(2) Because the disassembly of the elastic sleeve pin coupling is very troublesome, it is easy to deform or damage the cast iron coupling when repairing the pump and motor.
(3) The LT elastic sleeve pin coupling requires high relative radial displacement of the two shafts, which is 0.2 ~ 0.6mm, which makes it very difficult to find the concentricity of the coupling. In addition, due to loose bolts during operation, the vibration and noise of the pump unit will increase.
