Couplings and Coupling Systems – Requirements, Selection and Design

By Norbert Telaar on Jun 20, 2018

Regardless of the application for which a coupling is used – a variety of requirements must be fulfilled to ensure efficient and reliable operation of the coupling system. Undoubtedly, the coupling is a vital component of the entire propulsion line. Therefore, when designing a coupling, attention must be paid that the coupling is able to withstand the mechanical requirements, requires virtually no maintenance, operates trouble-free and, ideally, has a long service life.

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.

Chemical Processes for the Surface Treatment of Components (2)

By WP on Feb 21, 2018

This is part 3 of our series on surface treatments of components. Due to the great number of different chemical processes, we have split them up and explored these processes in the previous article:

  • Chromate conversion coating
  • Phosphating
  • Galvanizing
  • Plating
  • Black oxide.

This blog article covers the remaining chemical processes commonly applied for the treatment of component surfaces.

Chemical Processes for the Surface Treatment of Components (1)

By Lars Jahnel on Feb 07, 2018

In our first blog article we presented the most common mechanical processes for the treatment of component surfaces. In this second part, we address the most frequently used methods of chemical surface treatments. The decision as to which of the following treatments should be applied is predominantly influenced by design points of view, technical aspects and the intended appearance of the product.
