Why Every Component of a Cement Mill Counts in the Production Process

By Björn Schumacher on Jan 18, 2017

Operators of cement plants worldwide face the challenge to create their systems more efficient and reliable. Even though the production and consumption of this material is quite stable in Europe, there is a continuously growing demand in Africa, North America and Asia. For this reason, production needs to be optimized and therefore all components which are part of the drive to guarantee constant operation, minimal downtimes and low maintenance costs.

Listening, measuring, checking: Maintenance of flexible couplings

By Norbert Telaar on Dec 14, 2016

Especially in narrow spaces, couplings can only be inspected visually, because the coupling is hardly accessible with conventional measuring devices. Atypical operation noise or vibrations are generally the first signals that there is something wrong with the coupling.

Maintenance: Focus on couplings

By Norbert Telaar on Oct 26, 2016

Couplings in drive lines are of particular importance because they transmit power between the input and output side, and compensate for inevitably occurring misalignments of the units. Like other machinery elements, couplings need to be serviced at regular intervals. Only if the coupling is optimally tailored to the requirements of the operating conditions and subject to regular maintenance, can it contribute to ensuring the operating reliability and efficiency of a machine or plant.

Couplings for the safe operation of piston engine-powered CHPs: not too soft, not too stiff

By Sophie Keil on Oct 12, 2016

The demands made on the components in combined heat and power plants (CHP) are increasing. They have to be efficient, long-lasting and, in case of an emergency, must at least fulfill the safety requirements set forth by the Medium Voltage Guideline. Thomas Marterer, Product Manager at RINGFEDER POWER TRANSMISSION, explains how operators of CHPs can find the correct coupling for their plant: The coupling should withstand high temperatures and be neither torsionally too stiff nor too soft.

Video: Innovative Coupling Design Offers Adjustable Stiffness and Easy Replacement

By Sophie Keil on Sep 28, 2016

"The challenge to develop a highly flexible coupling is to design a coupling which has a particularly soft characteristic curve", explains Norbert Telaar, Head of Strategic Product Management at RINGFEDER POWER TRANSMISSION, the main task of his team. In the end they developed an innovation in coupling design.

Certification According to the Medium Voltage Guidelines: the Following Applies to CHPs

By Thomas Marterer on Sep 21, 2016

Pursuant to the supplement to the Medium Voltage Guideline in 2013, the certification directives for co-generation plants have been adopted and the obligation to furnish evidence of compliance with the BDEW guidelines of 2009 is now also binding for co-generation plants. As a result, certificates have to be furnished for CHPs connected to the medium voltage grid with reference to their behavior in the event of a failure.

Combined Heat and Power Units Assist in Securing Grid Stability, which particularly Challenges their Gensets

By Thomas Marterer on Sep 14, 2016

The amendment to the obligatory certification within the medium voltage guideline in 2013 catapulted combined heat and power units into a new league: they are now also in charge of stabilizing the dynamic German power supply network. This provides excellent opportunities for the technology, but it also means new obligations.

Flexible Stiffness – Why Engineers like Oxymora so much

By Sophie Keil on Sep 07, 2016

An oxymoron connects two contradictory terms. In the field of engineering this often means that the seemingly impossible has become possible. The same holds true for “flexible stiffness”. Learn what it is all about and let us know your personal favorite oxymoron.

Video: Highly Flexible Couplings for Highest Demands in Drive Systems

By Sophie Keil on Aug 31, 2016

Nowadays engineers are facing various challenges which can be solved by selecting the right coupling. Shocks, heat, cold conditions, efficiency and work safety: machines and their drives have to meet highest requirements.

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.
