Elastic sleeve pin couplingA pin with an elastic sleeve (rubber material) at one end is 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 was once the most widely used coupling in my country. It was formulated as a standard for the Ministry of Machinery in the late 20s: JB50-108 elastic ring pin coupling, which was the first in my country Standard 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.
