What are the factors that can reduce the service life of a metal bellows coupling?

By Thomas Marterer on Apr 18, 2018

It is generally assumed – and typical applications confirm – that metal bellows couplings reliably work over the entire service life of an installation, if the coupling is correctly designed. In the future, this can no longer be taken for granted as applications are becoming more and more dynamic. Such applications require you to consider additional criteria when selecting and designing a coupling. Read here about the most important factors which have to be taken into account.

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.

Friction Springs for Earthquake Protection of Critical Infrastructure Objects

By Lars Jahnel on Mar 21, 2018

What started almost a century ago as buffer between railway cars has now become a universally applicable damping element for almost all industry sectors – also as a protective element against potential damages to buildings and industrial facilities caused by earthquakes.

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.

Friction Springs for Earthquake Protection

By Lars Jahnel on Jul 19, 2017

If buildings are shaken by earthquakes this can lead to cracks, instabilities in the support structure and in worst case szenarios to the collapse of the building. To efficiently absorb the enormous forces and thereby protect both, person and material, nowadays sophisticated technologies are available.

Not all damages that a great earthquake will cause can be avoided. However, with Friction Springs there is a very high probability, that the building withstands an earthquake – like those in Christchurch/NZ in 2010 and 2011 – and is still operational and habitable.

How does a Friction Spring Work?

By Lars Jahnel on Jun 21, 2017

In a previous article we covered friction springs and their applications. This time we would like to explain the technical properties of a friction spring, how it works and why its features provide a variety of advantages compared to other damping systems.

Couplings in Aeroderivative Gas Turbines

By Thomas Marterer on Jun 07, 2017

Gas turbines are available in many different designs and the power output of the individual models varies considerably – from 200 kW to more than 400 MW. The performance of gas turbines for industrial applications typically ranges from 5 to 40 MW. Dependent on the power, the speeds vary from 3,000 rpm to 15,000 rpm. Please see below which couplings are typically used and which are the selection criteria.

Friction Springs - Experts in the Field of Damping Technology

By Sophie Keil on Mar 22, 2017

Friction springs are indispensible safety components in all fields of technology where suddenly occurring forces have to be taken up and kinetic energy absorbed, or where springs are required with relatively compact dimensions while also being able to sustain high forces. Expert friction springs are needed when it comes to the deceleration of moving masses in a quick, safe and precise manner.

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.

Maintenance and repair: Characteristics of gear couplings, steel disc couplings and (highly) flexible couplings

By Norbert Telaar on Nov 09, 2016

Couplings are not the most critical part of plants but they have to meet continuously changing requirements. Being reliable, efficient and robust is no longer enough – they should be easy to maintain in order to reduce costs and to avoid downtime. So for choosing the right coupling its characteristics in regard to maintenance and repair are playing a more important role.
