  What are the types of Marine couplings? Couplings  are mechanical parts used to connect two axes (drive shaft and driven shaft) in different mechanisms to rotate together to transfer torque. The two axes cannot be separated when the machine is running, and the two axes can only be separated after the machine is parked and the joint is removed. ​ Flange coupling  ( flange  coupling)  : the advantages of this coupling are low cost, simple overall structure, can transmit large torque, there can be no relative displacement between the two axes, no buffer. It is suitable for use in low speed, no impact, shaft rigidity, small and medium-sized work sites. Elastic pin coupling:  This kind of coupling in operation, torque is passed to the driven shaft through the two half couplings and the nylon pin in the middle. The advantage is that the baffle can be fixed by screws on the outside of the half coupling, and the anti-fall performance is good. In addition, it also...

  What Is A Marine Coupling? Marine coupling  is an important part of the Marine transmission system, which is mainly used to connect and transfer the power of the  Marine engine . It is able to convert the rotation of the engine into the power of the thrusters to propel the ship forward. There are many types of  Marine couplings , including rigid couplings and flexible couplings. Rigid coupling uses a rigid joint to connect the engine axis and propeller axis to each other, transferring power is stable and reliable, but the disadvantage is that it can not compensate the axis error, easy to produce vibration and noise. The flexible coupling adopts a flexible connection mode, which can compensate the axis error and prevent vibration and noise, but the stability is poor when transmitting power. The functions of  Marine couplings  include power transmission, compensation for axis errors and separation protection. In terms of power transmission, the coupling is ...
