Elastic pin couplingIt uses several pins made of non-metallic elastic materials and is placed in the flange holes of the two halves of the coupling. The two halves of the coupling are connected by the pins. The coupling has a simple structure, easy to manufacture, and flexible in assembly and disassembly. The components are more convenient, and there is no need to move the two couplings.
The elastic sleeve pin coupling uses a pin with an elastic sleeve (rubber material) at one end to be installed in the flange hole of the two halves of the coupling to realize the connection of the two halves of the coupling.The elastic sleeve pin coupling is characterized by simple structure, convenient installation, easy replacement, small size and light weight.Since the deformation of the elastic sleeve is not large when it is squeezed when it is working, and the matching 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 it compensates for the difference between the two shafts. The relative displacement is small.
The difference between them is:
1) The elastic pin is more commonly used, the transmission torque is relatively large, the effect of the elastic sleeve pin is better, but the elastic sleeve is a vulnerable part;
2) The elastic sleeve pin has no noise, the elastic pin has a certain noise, and the torque transmitted is different;
3) The elastic pin coupling is a nylon rod as the elastic element, and the elastic pin coupling is rubber or polyurethane as the elastic element, and the effect is different.
