The issue might be a faulty treadmill at a local gym, the need to update orthopedic surgery equipment or simply a train stuck in neutral at the toy store. Whatever the case may be, viewing e-mails in the marketing department at Torque Transmission is like opening Christmas presents every morning.
He was out. Nine years ago, Ross Rivard left the coupling industry for the shimmering new world of luxury automotive components at Lacks Enterprises, where he was immediately enveloped by platinum trim systems and chrome composite wheels. It was glitz and glam and as sparkly clean as the fresh-fromthe-dealership cars his products were embellished onto.
Four types of gear devices with great transmission ratios (simply called great ratio gears or GRGs) are discussed in this paper. They are strain wave gearing devices (SWGs), trochoidal gear reducers (TGRs), hypocyclic gear reducers (HGRs) and James Ferguson-type planetary drives (JFDs). The structures, advantages and basic performances of these four devices are compared. The latest design and strength analysis methods are also introduced. To conclude, the future tendencies of GRGs are predicted.
Engineers are often challenged with the seemingly impossible task of doing more with less. Customers want more power transmitted in a smaller space, they want more efficient designs, and, of course, they want to spend less money. So engineers are always looking for ways to squeeze the most out of their mechanical systems. They’re constantly working to maximize power density, increase energy efficiency and reduce costs to meet their customers’ needs.
We're pleased to present the first-ever March issue of Power Transmission Engineering.
A wide variety of companies displayed mechanical power transmission and motion control technologies at Pack Expo, held in November in Chicago. The event, which is the largest packaging and processing trade show in North America, attracted more than 48,000 attendees, according to show owner and producer PMMI. The four-day event included 2,352 exhibiting companies, an increase of more than 19 percent from the previous show in 2012.
The 8th International CTI Symposium on Automotive Transmissions, HEV and EV Drives took place in Rochester, Michigan from May 12-15. The event kicked off with its popular introductory seminar "Basics and Practice of Automotive Transmissions."
The mechanical components of your drive system play a major role in overall system efficiency. Don't cut corners.

A core part of what we do here is making sure that our readers – the people who design, buy and use mechanical power transmission products – know where to find the suppliers of technology they need.
Experts gathered at the 9th CTI Symposium to discuss the challenges of reducing noise, improving energy efficiency and meeting the changing demands of the marketplace
We’ve recently completed a major redesign of the powertransmission. com website. I know what you’re thinking. Big deal, right? Websites are redesigned every day. It’s not really news. You’re right, of course. We’re in the news business, and when companies send us press releases about their newly redesigned websites, our first instinct as editors is to respond the same way. So what. Big deal. Moving on.
Highlights from some of the gear, gear drive, power transmission component, software, materials and related exhibitors at Gear Expo 2017.
With Thanksgiving right around the corner, it's hard not to think of the smorgasbord most of us experience on America's most food-centric holiday. If your family celebrates like mine, then there's always plenty of food—and more importantly—plenty of choices.
Just over 10 years ago, we started publishing Power Transmission Engineering, and I'm proud to say we're still going strong.

End users and OEMs frequently specify "lubed-for-life" mounted bearings, thinking the lubed-for-life bearings will deliver the same life — without lubrication — as bearings that currently require periodic lubrication. The truth is it depends on many factors, and only a detailed review of the application and testing will provide a more accurate answer.

Managing Editor Randy Stott explains the recent updates and improvements to the website.
Norkol Converting Corporation is one of the nation’s leading independently owned converters and distributors of commercial printing papers. The company has full production capabilities and state-of-the-art machinery for winding, trimming and sheeting. The company utilizes traditional slitter re-wind equipment that unwinds, slits and then re-winds paper to new dimensions. These conventional re-winders, while typically producing new widths of paper with clean cuts, work at an inefficient, slow pace.
The use of motor structures which can concentrate magnetic flux allows ferrite PM motors to achieve performance and power densities that approach those of PM motors using rare earth magnets, but without the cost penalties and supply source concerns of rare earth magnets.

Q&A: My company manufactures high-speed metal forming machines. We have one application on a feed axis where we are encountering problems with the coupling...
Most manufacturers of shaft-mounted speed reducers offer torque arms for their products. However, in some situations, a machine designer may be required to design his own.
The world of high horsepower drives often calls for mechanical design to be approached from different perspectives. As motors, gearboxes and machines increase in size, power density can become disproportionate from one driveline component to the next, emphasizing the need for more rugged, robust and compact equipment.
Permanent-magnet, synchronous-torque motors offer significant advantages on high-energy-consuming and high-dynamic applications.
When talking about high-end machining or manufacturing applications that include direct-drive technology, one of the key advantages of utilizing this particular transmission method is its endurance. Because of the very nature of direct-drive motors they are able to operate at peak performance levels indefinitely — without any kind of wear or aging — as long as the motor isn’t pushed past its capacity. Unfortunately, because this isn’t a perfect world, unexpected things can happen which can cause the motor to overheat. Whether the heat source is due to a parameter being input incorrectly, or an unexpected external force causing more resistance than expected — it is important to have certain forms of thermal protection in place. Since torque motors are built in such a way that they cannot be repaired and yet maintain their efficiency, it is vital to prevent any overheating — thus precluding the need to purchase a new one.

Over the past several weeks, I've had quite an interesting back-and-forth e-mail conversation with John Pellegrino, an engineer, inventor and dreamer whose letter appears on page 8.
Compact loaders are employed where large machines have no access or are over dimensioned. New hydrostatic drives from ZF meet the demanding needs of this market.
In the publishing business we thrive on new ideas. We employ creative people who are constantly coming up with new and better ways to serve our readers and website visitors.

Reader John Pellegrino looks for advice on his pursuit of a positively engaged continuously variable transmission.
This paper describes two devices—a clutch and a differential— which are based on the Ikona continuously variable transmission (CVT).
In today's highly competitive world, the better someone understands the advantages and benefits of direct drive technology, then the more they will have an advantage in machine building, giving them an edge over their competition.
In the process of applying industrial drive products, we occasionally are misled into believing that we are applying horsepower. The real driving force is not horsepower - it is torque. This paper is developed to impart a deeper understanding of torque, its relationship to horsepower, and the types of loads we most frequently encounter.
