Safe Energy Absorption – DEFORM plus® Shock Absorbing Units

By Friedhelm Detzner on Jul 18, 2018

In our last blog article we compared the most commonly used damping systems in terms of their damping properties and highlighted the importance of installing such systems to protect your machines and components. Our comparison referred to dampers made of optimized synthetic polymers. In this article, we would like to present our shock absorbing units DEFORM plus®.

Safe Energy Absorption - Damping Systems by Comparison

By Friedhelm Detzner on Jul 04, 2018

If a braking device fails, or in the event of an operating error, moving masses can cause significant damage upon collision or impact. To avoid this, you should use a damping system that is tailored to your application, because the removal of such damage usually costs more than the purchase of suitable shock absorbing units.

What is the reason for using a coupling with limited end float?

By Norbert Telaar on Apr 04, 2018

A coupling is an element of a drive line that primarily serves the purpose of transmitting power from one shaft to another, thereby providing for the connection of the driving and driven machine. At the same time, shaft misalignments, e.g. caused by assembly inaccuracies, should be compensated by the coupling while generating minimum reaction forces.

The distinction is made between angular, radial and axial shaft misalignments which may also occur simultaneously. Depending on the coupling type you choose, the dynamic behavior of the entire drive line, and consequently of the machine and its production process, can often be influenced by adjusting the torsional stiffness of the coupling.

Coupling and Locking Assembly Options for Warehouse Automation Systems

By Ross Rivard on Nov 22, 2017

When it comes to automated warehouses, precision is key. Hundreds of shuttles and miles of conveyors must all work together to ensure products are transported successfully to their designated location for storage or delivery. Of all the components that play a role in the precision of these systems, do not forget about Couplings and Locking Devices – both of which are widely used in this application.

Basics of Coupling Selection: The Safety Factor

By Norbert Telaar on Mar 15, 2017

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.

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.

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.

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.
