||Series JN diaphragm coupling is a structural variety of the series JN. It enlarges the application fields of series JM. Under shorter shaft head spacing conditions, series JN can have the sleeve plug coupling, plum blossom elastic coupling,these old fashion couplings have big noise and easy to damage. The series JN diaphragm coupling has also the features such as the gravity center near the unit support, small addilional bending moment, smaller influence on the rotor dynamic property it is especially suitable for high speed light load unit such as turbo compressor.
||The flange gravity center of the intermediate plate type coupling is nearer the shaft support, and has more smaller additional bending moment, therefore it can more effectively reduce the influence of the additional bending moment on the shaft and on the bearing, compared to the opposite wheel type coupling.
||The intermediate plate type diaphragm coupling can greater improve the radial adjustment capacity of the coupling, reduce installation accuracy, the flexibillity is stronger, vibration-reducing effect is much better compared to the opposite wheel type coupling.
Shenyang Triocircle Machinery Factory is a professional manufacturer of couplings and universal joint shafts in China’s heavy machinery industry,whichis one of the largest coupling manufacturers in China and own many patents in coupling.
