(SPONSORED CONTENT)Mounted Bearing Locking Trends in Unit Material Handling Applications
A â€śone-size-fits-allâ€ť bearing selection does not apply universally â€” especially when it comes to lock reliability and the locking types of mounted bearings. The trend in unit material handling applications has shifted from traditional setscrew locking designs to newer concentric locking solutions. Concentric locking results in more near-perfect concentricity, quieter operation, increased lock reliability, higher speed of operation, and less damage to the shafting. The results: improved equipment performance and increased uptime. White Papers Courtesy of Regal Beloit

According to the Department of Energy (DOE), more than half of all electrical energy consumed in the U.S. is used by electric motors. To address this, several years ago, the DOE conducted a technical study as to what could be done to raise the efficiency levels of âÂ€œsmallâÂ€Âť motors. After years of study and litigation, the Small Motor Rule (SMR) was passed that covers two-digit NEMA frame single- and three-phase ¼ through 3 horsepower motors in open enclosures.
EnergyâÂ€™s endless energy efficiency game of whack-a-mole, motors have historically always been one of the go-to moles. TheyâÂ€™ve been in the spotlight since 1992. Over the past few decades, repeated efficiency laws have seen motor efficiency get whacked into tighter and tighter shape.

This issue, we're pleased to present our annual Buyers Guide. It's our comprehensive directory of suppliers of mechanical components, including gears, bearings, motors, couplings, clutches, brakes, gear drives and more. This directory represents our best effort to give you updated information about the companies who can provide you with the components you need to design, build and maintain better machinery.
If youâÂ€™re an electrical engineer you know how an electric motor works; if you arenâÂ€™t, it can be extremely confusing. Therefore, hereâÂ€™s the simplified explanation (or the âÂ€œhow an electric motor works for dummiesâÂ€Âť version) of how a four-pole, three-phase AC induction motor works in a car.
Our politicians in Washington continue dithering over the Obama administration energy bill aimed at developing alternative, green sources of energy production. As a result, when this country will have a viable energy program in place is anyoneâÂ€™s guess, given the usual D.C. gridlock. And yet, Americans can take more than cold comfort in the fact that at least some government agenciesâÂ€”U.S. Department of Energy (DOE)âÂ€”and the private sectorâÂ€”some major manufacturersâÂ€”are doing more than their share of work in trying to harness our existing, fossil-based energy sources in such a way that they are used to their best efficiencies.
You may have noticed a lot of merger and acquisition activity lately in the power transmission industry. What does it mean?
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.
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.

Are you looking for one simple formula to help you choose between centralized and decentralized motor control? Unfortunately, such a formula does not exist. However, evaluating the overall size of the system, comparing labor and material costs, and maintaining flexibility can help guide engineers in the right direction.
Who doesn't love LEGO? While no parent enjoys stepping on them in the living room, I'd rather have my kids building a castle, a tower or a giant LEGO wind mill then watch their faces glued to their cell phones for hours on end.
Experienced operators can often tell if a machine is not working properly, on the basis that it does not âÂ€˜sound right.âÂ€™ The same principle can be applied âÂ€” using modern electronics âÂ€” 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.
The integration of manufacturing information into gear design software reduces cost during the design process by avoiding time-consuming back and forth between the design and manufacturing departments. The challenging task for such software is ensuring the design engineer does not need specific manufacturing expertise. Otherwise he or she would be overwhelmed and not use such a feature.
Staying sane is tough when the world seems so crazy, and having your brain plugged directly into the news cycle doesn't help. I know it's not healthy to keep refreshing my news feed. But the coronavirus has everyone scared, myself included.
Regarding 3-D printing of gears and machine tools, etc. âÂ€” does plastic gearing have a future in 3-D printing/additive manufacturing?
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.
Remember Paul Winchell? Sure you do - if you are a child of the âÂ€™50s. Who of that period does not recall ventriloquist dummies Jerry Mahoney and Knucklehead Smiff?

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.
How does one draw and mesh involute gear teeth in AutoCAD?
There are few things in this world that elicit such a gleeful, childlike sense of wonder as does the word âÂ€œhoverboardâÂ€Âť.
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?
LetâÂ€™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 âÂ€œgoes without saying.âÂ€Âť Yet, not all that long ago,Tony Werschky had to say it.
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 SKFâÂ€™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).
