Dynamical Torsional Etiffness: Some Couplings Need Finer Tuning

By Simon Graf on Aug 24, 2016

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.

All Couplings are not Equal: Smart Engineering Considers Both Technical and Economic Requirements

By Volker Carl on Aug 17, 2016

Bending stress, torque shock, natural frequency and resonance: all the machinery elements in drive systems – i.e. above all axes, shafts, bearings and couplings – must withstand such strains. The coupling plays a prominent system-influencing role which it continues to fulfill better and better due to advanced development.

Reciprocating Engines in Combined Heat and Power Units: Is Higher Power without Loss of Energy Efficiency Possible?

By Thomas Marterer on Aug 03, 2016

The combined heat and power technology (CHP), in particular co-generation units, have long been a part of the industrial energy transition. However, the large potential of combined heat and power units is still underutilized. The reason for this, among others, is because of the properties of the installed drive technology: for instance, the non-uniform torque of reciprocating engines. New components promise more power with consistently good energy efficiency.

Stiffness and Damping: This is what Engineers have to Consider when Tuning a Coupling

By Simon Graf on Jul 20, 2016

Stiffness describes the ability of a body to resist elastic deformation. The transmission of power would not be possible without stiffness. However, there are events which should not be transmitted, such as torque peaks and shock loads. In order for a system to withstand such loads, it is damped. Engineers are confronted with the challenge to tune stiffness and damping in a vibratory system in such a way that reliable operation, essentially free of load peaks, is ensured.

New Coupling Design Offers Stiffness Adjustments

By Ringfeder News on Jul 09, 2015

Motor shaft couplings have to strike a delicate balance when it comes to stiffness. On the one hand, they have to be rigid enough to transmit torque efficiently. On the other, they have to be flexible enough to handle any misalignment between the motor and the drive shaft. Our latest coupling design can help you strike that balance.

Selectively Compliant Coupling Protects Gearboxes

By Ringfeder News on Jun 17, 2015

The big gearboxes that drive cable drums do not come cheap. Yet engineers often
make a design mistake that can shorten the gearbox’s working life. This mistake
involves the use of a rigid, direct coupling between the gearbox output shaft and the cable drum.
