We have a system where a servomotor will rotate a big steel disc.
To obtain an allowable speed of the motor for the speed of the disc we want, there will be at least a gearbox after the motor, and maybe also a chain or belt with reduction factor (chainwheels with different diameter).
We know the accelerations we want from the disc, so we can calculate if the motor torque and speed is allowable, and can select the gearbox that is best fit, and if neccesarry also the
speed ratio of the chain or belt.
The disc will have quite some inertia. Now I am worried about the stiffnes of the chain or belt (if we use one).
I suppose choosing the ratio of the gearbox so that no chain or belt is necessary anymore will be the stiffest construction.
But the fact is that we already have a gearbox that we might use.
In that case a chain or belt will be necessary for further speed reduction.
But how can I know in design phase if the drivetrain will be stiff enough? Especially when stopping very fast, I want no oscillations. What tools or formula's can help me in that determination?
The servodrive and the gearbox is Siemens.
