Description

technical field [0001] The invention relates to a manufacturing process of a high-elastic coupling, in particular to a high-elastic coupling rubber for ship machinery and a vulcanization preparation method thereof. Background technique [0002] The high elastic coupling of marine machinery is an important connecting part between the diesel engine and the gearbox. It can compensate the axial displacement, radial displacement and angular displacement of the adjacent mechanical axis. It is used to transmit the power of the diesel engine to the auxiliary machine end. At the same time There is a certain delay in the time of power transmission, that is, the phase difference. The highly elastic coupling transmits torque through elastic elements, can adjust the torsional characteristics of the power system, and can effectively absorb vibrations, reduce the resonance speed, improve the working condition of the shafting system, and prolong the maintenance cycle and service life of the...
