MSC Design Variations The MSC coupling is available in standard and half stiffness versions for both flywheel to shaft and shaft to shaft applications. The MSC coupling can be adapted to meet customer needs as can be seen from some of the design variations shown below. Cardan Shaft Coupling Lightweight Anti-Magnetic Coupling Cardan shaft coupling to give high misalignment capability, low axial and angular stiffness and high noise attenuation. Aluminium coupling for use on military applications requiring low weight, high misalignment and low magnetic permeability. Coupling with Radial Support...

MSC Technical Data 1.1 Torque Capacity - Diesel Engine Drives The MSC Coupling is selected on the “nominal torqueTKN” without service factors. The full torque capacity of the coupling for transient vibration whilst passing through major criticals on run up is published as the Maximum Torque TKMAX 2.1 Axial Stiffness The axial stiffness of the coupling is linear and independent of applied torque as shown on page 13. 2.2 Radial Stiffness The radial stiffness of the coupling is linear and independent of applied torque as shown on page 13. TKMAX = 3 X TKN. 2.3 There is additional torque capacity...

2.5 Prediction of the system torsional vibration characteristics An adequate prediction of the system torsional vibration characteristics can be made by the following method. 2.6 2.6.1 Use the torsional stiffness as published below which is based upon data measured at a 30°C and the dynamic magnifier at 30°C. (M30) 2.5.1 Use the torsional stiffness as published below which is based upon data measured at a 30°C ambient temperature. 2.6.2 Compare the synthesis value of the calculated heat load in the coupling (Pk) at the speed of interest to the “Allowed Heat Dissipation”(Pkw). 2.5.2 Repeat the...

Damping Characteristics Coupling damping varies directly with torsional stiffness and inversely with frequency for a given rubber grade. This relationship is conventionally described by the dynamic magnifier M, varying with hardness for the various rubber types. M= K Cω iωt + ω) ae (k + ic δ = Torque δ Deflection = aeiωt tan δ = This property may also be expressed as the Damping Energy Ratio or Relative Damping, ψ , which is the ratio of the damping energy, AD, produced mechanically by the coupling during a vibration cycle and converted into heat energy, to the flexible strain energy Af with...
