Effectiveness, safety, customization, profitability – the diverse and complex requirements in drive and damping technology are constantly increasing and changing. How do development engineers approach them? What specific solutions do they create for different industrial and technological sectors? How are pioneering innovations successfully achieved that provide real added value? We discuss this and much more in our The Engineer's Blog.

Basics of Coupling Selection: The Safety Factor

Engineers need to consider several aspects for selecting the appropriate coupling such as the type of installation, primary and secondary connection, available space of installation, ease of mounting and dismounting as well as maximum rotational speed and resilience of the coupling. To compensate physical parameters or changes that are not obvious the safety factor, also known as safety multiple or safety coefficient, is taken into account.


Dynamical Torsional Stiffness: Some Couplings Need Finer Tuning

The coupling is normally the softest element in the drive line, literally – but by no means the weakest link of the chain. Its configuration plays a decisive role for the functional capability of the driving and driven machine and for the reliability and lifetime of the entire drive system. The optimum adjustment of the coupling to the connected machine units is especially important in all cases where failures and breakdowns are not allowed to occur.
