Product Description Technical Parameters Specification1.Rated toruqe TN is the maximun average torque as the diesel engine is in stable operation. TN=9.55 Pw in the formula is rated power(Kw)and n is rated rpm(r/min).2.TKN 30 is the rated torque of the coupling when the temperature is 30oC.As the temperature is higher than 30oC and the prime mover differs,the rated torque of the coupling TKN 30≥k·9.55.(k please refers to chart 1)3.Maximun torque TmaxTmax is the maximun torque of the system in normal operation.The maximun toeque will occur but in shout time.Tmax cannot be higher than the maximum torque of the coupling TKmax.For occasional cases(disconnection,synchronous motor out-sync,emergency stop),the shock torque cannot be high than 1.5TKmax.4.Variable torque TwVariable torque is the vibration torque which superimposes on the average torque Tm.As the diesel engine is in stable operation,Tw cannot be higher than allowable variable torque Tkw.5. Power lossCertain vibration energy will be turned into heat to flexible element as damping exists.The superposition of power loss in each order calculated based on the following formula and cannot be higher than allowable value.In the formula,Twi-variable torque(kNm)iniorder Cr-dynamic torsional stiffness of coupling (kNm/rad)ψ-relative damping i-Harmonic frequency n-rpm(min)PKv30 is the data when environment temperature is 30oC;When the environment temperature is 60oC,Pkv60=Pkv30·0.65;When the environment temperature is 80oC,Pkv80=Pkv30·0.4;6.Relative dampingRelative damping is the ratio between damping power WD tuned into heat in each vibration cycle and elastic deformation power WE.7.Axial displacement and radial displacementAxial displacement and radial displacement is the instant maximun deviation of the coupling.It is not the shafting alignment deviation.For shafting alignment please refers to installation manual.8.As influenced by the physical characteristics of flexible elements,the data in the chart is allowed to have some deviation.The deviation range is±15%and±20%based on different structures,types and sizes.9.Environment TemperatureEnvironment Temperature is the air temperature surrounded the element surface.10.VentilationThere shall be enough space and ventilation around the coupling.There shall be enough ventilation side face and holes on the cover during design period.Type Selection GuidanceThe main flexible elements are made from rubber and metal.The flexible element absorbing vibration will produce heat(mechanical energy turns to heat).The transmit capability reduces as the temperature rises.As the operation temperature reaches 80C°,the transmit capability is about 40%.Coupling rated torque TKN=K·9.55·Pw/nPw-diesel engine power(KW) n-diesel engine rated rpm(r/min) K-operation condition factor Prime moverOperation machineI typeII typeIII typeIV typeV typeElectric motor1.31.51.71.92.34cylinder and above diesel engine1.51.71.92.12.5Single cylinder and double cylinder diesel engine22.22.42.63Note:there are 5 types of operation machinesI type:machines with very little torque changeII type:machines with little torque changeIII type:machines with medium torque changeIV type:machines with medium torque change and shock loadV type:machines withhigh torque change and shock loadRelated products Our HistoryHangzhou Cagon Transmission Technology Co., Ltd. is well-known in the shipbuilding field.
