Case Study: Application of HENFEL bearing housings in iron ore pellet roller screens

By Matheus Mendes on Aug 28, 2019

Before we dive into the case study, a little background information may be necessary. An iron ore pellet is a tiny iron ore ball (between 8 and 18mm of diameter) composed of pellet feed and iron ore fines, which are the finest forms of the iron ore, mixed with a flux (in Brazil usually limestone) and a thickener, which gives the pellets their consistency.

Case Study: Application of a Locking Assembly in a Ball Mill for Cement Production

By Dheepan Ramalingam on Jun 05, 2019

In this article we take a brief look at a locking assembly solution of RINGFEDER POWER TRANSMISSION which was developed for a cement plant after the mill operator had experienced repeated failures of its equipment.

Case Study: Application of Shrink Discs in Industrial Gearboxes

By Carlos Rohrig on Jan 23, 2019

Shrink discs are external locking devices that provide a high capacity interference fit as well as all positive features of a conventional connection method, but which are much easier and faster to assemble and dismount. When a torque is transmitted through the connection of a shaft and a hollow shaft, the contemporary solution is to use a shrink disc instead of a failure-prone keyed connection. Shrink discs are typically available with inner diameters from 14 mm up to 500 mm.

Case Study: Coupling Application in Sugarcane Handling

By Matheus Mendes on Nov 28, 2018

The sugarcane industry is one of the most flourishing segments of the Brazilian Economy. With a production of up to 624 million metric tonnes of sugarcane in the 2017 harvest season, the country holds the world record production for both sugar and ethanol from this raw material. A broader view reveals that more than 37 million tonnes of sugar and 27 million cubic meters of ethanol were produced to meet national and expanding global demand.

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.

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.

Mechanical Processes for the Surface Treatment of Components

By Lars Jahnel on Jan 24, 2018

The surface finish of components used in the field of mechanical engineering as well as of other products is not only determined from a design point of view, but is mainly defined by the technical aspects. From the onset, the specification of the requirements regarding the condition of component surfaces, e.g. of a shaft coupling, often has far-reaching consequences on the product development process, the resulting costs and, eventually, on the succes of the final product.

How to Achieve Efficiency: Sustainable Maintenance Management Requires Cooperation

By Norbert Telaar on May 24, 2017

Designers of plants and machines strive for the optimal selection of a coupling for the complete system with many variables requiring consideration. In most cases the main focus is not how maintenance-friendly the product is. Yet – one might say. For a sustainable improvement of the longevity and efficiency of plants, a stronger involvement of maintenance is a must.

Digital Change & Innovative Thinking

By Sophie Keil on Dec 21, 2016

Topics as varied as Big Data, Industry 4.0, Digital Transformation, Crowdworking, Generation Y , Work 4.0 and 3D-printing have been discussed in 2016, and many of these will have significant influence on the working world over the next few years. This also applies to mechanical engineering. We would like to refer to three terms that have gained importance in 2016.
