YL type flange coupling is abbreviated as flange coupling, which is a rigid coupling. It connects two flanged half couplings to the two shafts with ordinary flat keys, and then connects the two half couplings with bolts. The shafts are connected as a whole to transmit movement and torque.
YLD type flange coupling (also known as flange coupling) is the use of bolts to connect two flange (flange) disc type half couplings, and the two half couplings are respectively connected to the two shafts with keys to achieve The two shafts are connected to transmit torque and movement.
The JQ type-clamping shell coupling uses two axially split shells, which are clamped by bolts to realize the connection of the two shafts. The torque is transmitted by the friction between the two halves of the coupling surface, and the flat key is used for Auxiliary connection.
