8 When a Good Gear Drive System Goes Bad (October 2012)

Even when the critical components of industrial power transmission gear drive systems are properly designed, specified and manufactured consistent with application requirements, performance problems can develop over time and failure may follow.

9 How Does An Electric Motor Work (October 2016)

If you’re an electrical engineer you know how an electric motor works; if you aren’t, it can be extremely confusing. Therefore, here’s the simplified explanation (or the “how an electric motor works for dummies” version) of how a four-pole, three-phase AC induction motor works in a car.

10 Opening the Envelope on Bearing Vibration (September 2016)

Experienced operators can often tell if a machine is not working properly, on the basis that it does not ‘sound right.’ The same principle can be applied — using modern electronics — to identify the exact cause of the problem. Sensitive accelerometers can detect and analyze the vibrations from industrial equipment, highlighting problems such as misalignment or bearing imbalance. The technique is known as vibration analysis. It can identify bearing failure in the very early stages, when there is a microscopic defect on the raceway, for example. The problem is that the identifying signal is usually drowned out in all the other noise emanating from the machine.

11 The SKF High-Capacity Cylindrical Roller Bearing (Spring 2007)

Th e ISO defi nition of a full- complement bearing states that the bearing does not have a cage. When that defi nition was written, it was not technically possible to have a full-complement bearing with a cage. But SKF’s new high-capacity cylindrical roller bearing combines the load-carrying capacity of a fullcomplement bearing with the benefi ts of a bearing with a cage (Fig.1).

12 Steps Towards Revolution (December 2015)

The revolution goes by many names: machine-to-machine communication, smart manufacturing and the Industrial Internet, to name a few. In Europe, the prevailing term is Industry 4.0. In Germany, where that phrase was coined, the government is putting down €200 million to cultivate a lead in the industry. The McKinsey Global Institute estimates that its potential economic impact will be almost $4 trillion (or more) by 2025. Enthusiastic evangelists will tell you that the Industrial Internet is the most important advance in their industries that they’ve seen in their decades-long careers.

13 ISO-AGMA Standards: Specific Sliding Defined (March 2017)

Does the definition of specific sliding mean the same between ISO 21771:2007 and AGMA 917-B97? In ISO, specific sliding is the ratio of the sliding speed to the speed of a transverse profile in the direction of the tangent to the profile. In AGMA, specific sliding is ratio of gear tooth sliding velocity to its rolling velocity.

14 Hovercraft Technology Taking Us Back to the Future (December 2015)

There are few things in this world that elicit such a gleeful, childlike sense of wonder as does the word “hoverboard”.

15 Computing Gear Sliding Losses (February 2020)

As concerns surrounding the environmental impact of fossil fuels continue to grow, so does the need to produce vehicles with higher overall efficiency. The importance of enhanced vehicles has spurred drivetrain component manufacturers to study every aspect of efficiency loss in their products. The gearbox is a key contributor to the overall drivetrain efficiency.

16 Intelligent Integration (June 2015)

In this issue’s cover story, Stefan Hantke describes an evolving marketplace that requires smarter components and more integrated solutions. In fact, Hantke, who was recently named head of global industrial sales for the Schaeffler Group, goes so far as to predict that within a few short years, every bearing will have a wire coming out of it.

17 Disinfecting the News Cycle (March 2020)

Staying sane is tough when the world seems so crazy, and having your brain plugged directly into the news cycle doesnâ??t help. I know it's not healthy to keep refreshing my news feed. But the coronavirus has everyone scared, myself included.

18 Purchasing Efficiency (September 2018)

You may have noticed a lot of merger and acquisition activity lately in the power transmission industry. What does it mean?

19 Choose the Form (June 2018)

In the 1984 film Ghostbusters, Bill Murray and company were asked by Gozer the Gozerian to "choose the form" of their destructor. It was a no-win scenario for the heroes, because no matter what they chose, they were still going to face death

20 Built for Speed (March 2018)

Japan's Electric Aspark Owl Does 0-to-60 MPH in 1.9 Seconds!

21 Fluid Couplings vs VFDs for High Inertia Rotating Driven Loads (September 2017)

As the old adage goes, "There is more than one way to skin a cat." In the early stages of any project, system designers are faced with choices; whether they are designing a new application or retrofitting an old one, they need to determine what is the most efficient, economical and practical way of completing the task at hand. Though there are usually at least two viable means to accomplish the task, the first step is always to review and weigh the merits of each option.

22 The 5 Golden Rules of Gear Buying (February 2015)

Let’s be clear about something up front here: Delta Gear does not make parts for lawnmowers. This is a fairly flippant point that falls under the timeless, clichéd designation of “goes without saying.” Yet, not all that long ago,Tony Werschky had to say it.

23 Grease Lubrication Mechanisms in Rolling Bearing Systems (October 2013)

Grease lubrication has clear advantages over oil lubrication: Grease does not leak easily; it has sealing properties; and it protects bearing surfaces from corrosion. Its disadvantages are grease-life limitations and a limited cooling ability. Moreover, in some applications there is a risk of grease starvation, which leads to reduced lubricating films. However, if the right grease, sealing system and/or lubrication system are chosen, then grease lubrication offers clear benefits. This article summarizes aspects of grease lubrication mechanisms in rolling bearings.

24 Remembering Paul Winchell - A Man with Heart to Spare (December 2011)

Remember Paul Winchell? Sure you do - if you are a child of the ’50s. Who of that period does not recall ventriloquist dummies Jerry Mahoney and Knucklehead Smiff?

Q&A with Harald Poesch, product marketing manager for servomotors at Siemens Drive Technologies.

26 Coastal Question Marks (October 2010)

Does the U.S. renewable energy solution lie offshore? An update on the status of offshore wind projects.

27 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 Good Purchasing Personnel Are a Priceless Investment (March 2014)

Seems simple enough doesn't it? It is most decidedly not. Indeed, one can make the case that--aside from uppermost management (or ownership)-- no one else in a heavy/high-tech manufacturing concern has more ownership of the company's everyday needs and necessities than the purchasing department.

29 Servo Motor Performance at Stepper Motor Prices (April 2015)

Enhancing production with — and for — less is the standing order in today’s manufacturing world. Speeding up production while at the same time looking for ways, to cut, for example, energy costs, is a tricky equation with no single answer; where and how management goes about achieving that can take several paths.

30 3-D PRINTING IS HERE! (March 2015)

Necessity is the Mother of Invention, goes the bromide, but this 3-D printing thing is taking manufacturing to an entirely different — yes — dimension.

31 3-D Printing and Plastic Gears (March 2015)

Regarding 3-D printing of gears and machine tools, etc. — does plastic gearing have a future in 3-D printing/additive manufacturing?

32 Working in AutoCAD (April 2014)

How does one draw and mesh involute gear teeth in AutoCAD?

33 Diametral Pitch Calculation (April 2015)

Circular pitch gives me the size of the teeth in my mind, but diametral pitch does not. What is the purpose of the diametral pitch concept? Does it merely avoid pi in calculation?
