The ATEX Directive - Example of its Application in Practice

By Norbert Telaar on Dec 06, 2017

The term ATEX is derived from the French denomination "Atmosphères Explosibles" (explosive atmospheres): The ATEX Standard comprises the Equipment Directive 2014/34/EU as well as the Workplace Directive 1999/92/EC. In a previous article about the ATEX Directive we put more emphasis on general issues and theory. In this article we use the example of a flexible claw coupling to explain in more detail how this standard is implemented in practice.

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.

The Development of Locking Assemblies

By WP on Nov 08, 2017

Today, Locking Assemblies and Shrink Disks are standardized elements which provide a frictional connection between a shaft and a hub. They are not only capable of reliably transmitting torque, but of axial and transverse forces as well as bending moments, too. Oskar Peter is the father of the Locking Assembly. He recognized back in the 50`s that a locking assembly, in contrast to a key, is able to transmit considerably higher torques, thus allowing the engineering of much thinner and shorter shafts.

Trade Fair Review: Exposibram 2017, Belo Horizonte

By WP on Oct 25, 2017

The 17th edition of the biannually held EXPOSIBRAM took place from September 18th to 21st in Belo Horizonte (MG), Brazil. With a floorspace of 12.000 m², this exhibition is considered one of the greatest mining events in South America, gathering representives of government authorities, contractors as well as private organizations in the same place. EXPOSIBRAM also hosts the Brazilian Mining Congress, which is organized by IBRAM (Brazilian Mining Association).

Review: DGEB Conference 2017, Weimar

By Lars Jahnel on Oct 11, 2017

This year, the 15th D-A-CH Conference, which is organized by the Societies of Earthquake Engineering and Structural Dynamics in Germany (DGEB), Austria (OGE) and Switzerland (SGEB) took place on September 21 and 22. September.  

This gathering of experts is conducted biennially and serves both as the exchange of knowledge between seismologists and engineers and the presentation of current scientific findings and experience gained from field applications. In addition, companies operating in the fields of earthquake engineering and structural dynamics as well as manufactures of earthquake protection systems had the opportunity to present their application solutions in the foyer of the Bauhaus university.

Measuring Methods and Measuring Errors

By WP on Sep 27, 2017

Some weeks ago, we addressed the historical development of measurement technology. Today we would like to discuss the different measuring techniques and methods which help determine various parameters of a part being measured. Let's start with a few basic terms before we give a short overview of the most common measuring methods.

API – More than a Standard

By WP on Sep 13, 2017

In this blog article we are going to take a closer look at the API Standard 671 which specifies the requirements for special purpose couplings used in the petroleum, petrochemical and natural gas industries. This Standard has been developed by the American Petroleum Institute (API), which is not to be confused with the identical abbreviation used in the IT field (Application Programming Interface). Let's begin with a few details about the institute that gave the name to the API Standard.

End-To-End Coupling Solutions for Cranes and Hoists

By Ross Rivard on Aug 30, 2017

When it comes to gearbox coupling applications, some misalignment is unavoidable. This is especially true for cranes and hoists due to their very heavy loads. Fortunately, you can manage misalignment by choosing the right couplings. Here are some of your options specifically for cranes and hoists.

Balancing of Shaft Couplings

By Frank Richert on Aug 16, 2017

A virtually rotational-symmetrical component may have an unbalance caused by production tolerances or non-homogeneous structure in the material. Such unbalances in a drive system can not only lead to considerable vibrations during operation, but, in the long run, can also lead to failures of individual components or even of the entire drive system. As speed constitutes one of the decisive influences here, balancing is always performed for a certain speed. As a general rule, this is the nominal speed of the drive system.

General Measurement Technology & its Historical Development

By Sophie Keil on Aug 09, 2017

Measuring processes unconsciously cross our daily paths more often than we are aware. Whether it is about scooping coffee for the coffee maker, the temperature of the coffee or the speedometer in a car - we encounter measurement technology everywhere. But, what is “measuring”?

A well suited definition is given here: “Measurement enables us to make statements about a measured parameter in relation to a unit of measurement”. Measurement technology allows the determination of parameters such as length, mass, temperature etc.
