The editor tells you the reason for the damage of the high elastic coupling

　　1. Principle:High flexibilityCouplingThe main elastic drum shapeGear couplingIt is a torsional load-bearing rubber component. The rubber component can be designed in single row or multiple rows. Each rubber component has a variety of standard stiffness to choose from, which can meet the stiffness requirements determined by the torsional vibration calculation in a wide range. Shaft.Use high in ship power systemFlexible couplingThe main purpose is to transmit power and torque, compensate for radial, axial and angular alignment errors, and compensate for oscillations of rotational momentum.Adjust the natural vibration frequency of the system.High flexibilityPin couplingIt has the characteristics of light weight, convenient installation, large displacement compensation in all directions, large damping, strong vibration absorption ability and frequency modulation ability, etc., which can better protect the main coupling, gear box and shaft system.

　　2. Reason analysis:

　　1) The elastic shock absorber of the main engine sinks, causing the shafting to be misaligned and generating additional torque! This may be very large for new ships.

　　2) High elasticity elastic pin coupling rubber drum gear coupling heat and fracture accident;

　　3) Matching problem: Only the various equipment in the shafting, such as diesel couplings, high-elasticity pin couplings, gearboxes, other parts of the shafting, propellers, etc., have good designs and complement and support each other. Both improve the design level individually, so that the ship designed in this way is a high-quality ship in the sense.

　　4) The reason is complicated, and it needs to be analyzed in detail!
