● Generator output, speed and sense of rotation
● Mass moment of inertia of all rotating parts or a total inertia value of the rotor, including
the shaft
● Torsional stiffness or dimensions of the shaft
● Material of the shaft including tensile strength and modulus of rigidity
● Drawing number of the diagram or drawing
Flexible coupling/clutch
If a certain make of flexible coupling has to be used, the following data of it must be informed:
● Mass moment of inertia of all parts of the coupling
● Number of flexible elements
● Linear, progressive or degressive torsional stiffness per element
● Dynamic magnification or relative damping
● Nominal torque, permissible vibratory torque and permissible power loss
● Drawing of the coupling showing make, type and drawing number
Operational data
● Operational profile (load distribution over time)
● Clutch-in speed
● Power distribution between the different users
● Power speed curve of the load
17.6 Turning gear
The engine is equipped with an electrical driven turning gear, capable of turning the flywheel
and crankshaft.
