1 Soft Starters vs. Variable Speed - Or Both (June 2011)

Given that many different hydraulic systems recommend the use of either frequency converters or cyclic control (soft starter technologies), the question must be asked - Which one of these solutions is the most cost-effective in reducing energy consumption and providing the most satisfactory payback time?

2 Homogeneous Geometry Calculation of Arbitrary Tooth Shapes: Mathematical Approach and Practical Applications (February 2016)

This paper provides a mathematical framework and its implementation for calculating the tooth geometry of arbitrary gear types, based on the basic law of gear kinematics. The rack or gear geometry can be generated in two different ways: by calculating the conjugate geometry and the line of contact of a gear to the given geometric shape of a known geometry (e.g., a cutting hob), or by prescribing the surface of action of two gears in contact and calculating the correspondent flank shapes.

3 The Test Run (March 2016)

Modeling and simulation is a key driver of innovation. Whether it’s general manufacturing, consumer goods or life sciences, the ability to realistically model and simulate the response of parts, sub-systems and complete assemblies to increase accuracy and repeatability is vital in today’s analytical world.

16 How to Get the Most Realistic Efficiency Calculation for Gearboxes (April 2015)

In recent years the estimation of gearbox power loss is attracting more interest — especially in the wind turbine and automotive gearbox industry — but also in industrial gearboxes where heat dissipation is a consideration as well. As new transmissions concepts are being researched to meet both ecological and commercial demands, a quick and reliable estimation of overall efficiency becomes inevitable in designing the optimal gearbox.

17 Hardware-Software Synergy Automates Power Plant Data Collection (October 2009)

Robotics and other advanced automation technology systems are viewed as a looming threat to some in the plant maintenance field. Although there is a constant battle for some workers to remain useful while machines are continuously fulfilling more roles on the plant floor, there are those who in turn have found a better use of their newly freed time.

18 Energy Efficiency by Using Innovative Bearing Solutions (August 2010)

Based on simulation methods and calculation tools developed by the Schaeffler Group and presented in the first part of this paper, three approaches regarding increased efficiency based on rolling bearings are presented.

19 Beyond the Quick Fix - Supply Chain Software (April 2009)

In order for a company to be as efficient as possible, production, inventory and distribution components must be a top priority. A focused supply chain that gets the right materials to the right places in the allotted time frame encourages repeat business. These are concepts somewhat overlooked by many business executives in today’s economy.

20 The Green Revolution - A Global Win-Win (February 2009)

Green technology is more than changing a couple of light bulbs or reducing waste. In 2009, the concept is relevant in every facet of manufacturing as companies make a greater push towards energy efficiency and sustainability. In the power transmission and motion control fields, this technology has been integrated into the daily routine, both as an environmentally friendly business venture and a way to offer green products to customers. It’s apparent that the revitalization of manufacturing, both here and abroad, will center on energy technology.

24 Gear Design Software, Engineer Beware (February 2014)

When software goes bad, what do we call it? System failure? Human failure? A virus? A number of words will work. How about this? Glitch. It has that onomatopoeic quality that fairly screams, Downtime! And with good reason -- software-generated miscalculations can have very expensive -- if not perilous -- repercussions.

28 Effective Management Can Reduce Energy Costs Millwide (December 2012)

It’s as true in pulp and paper as it is in many other industries: the continued rise in energy prices has put a squeeze on margin and profits. Papermakers know that to maintain margin, they must effectively manage their energy costs.

29 Gear Wear Calculation and Prediction (February 2015)

Wear is a very important topic for dry running plastic gears. Over the past few years, the authors have worked closely with a number of manufacturers of plastic gears to investigate the problems of gear wear in detail. Together they have developed a calculation method that can be used to predict where and when local wear will occur on a tooth flank. Their findings have also just been published in the final version of VDI 2736.
