The technology continues to evolve in chain- and belt-driven systems
Chain and sprocket drives of one form or another have been driving machines and conveying materials for over a thousand years. The chain manufacturing industry has developed numerous types and sizes of drive chains. Although it is a mature form of power transmission, there are still many industrial applications for which drive chain is suited. It is economical, resistant to shock loads, easy to install, has the ability to transmit high torque, operates in hostile environments, and is efficient. Chain and sprocket drives are highly engineered and manufactured within close tolerances.
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.

Much of the industrial energy being consumed by systems is wasted through inefficiency. For this article, a system will be defined as the following components working together: electrical input power, variable frequency drives, induction motors, gearboxes and transmission elements (chains, belts, etc.).
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 todayâ™s economy.

As with just about everything else in the manufacturing world â” and all which that universe entails â” it depends. After all, thatâ™s why the art of manufacturing is a process â” not a one-system-fits-all discipline. Yes, once that process has been properly designed and correctly implemented for a given manufacturing production need, it may well run like the astest, smoothest cookie-cutter-type operation ever devised.
What is the general consensus on the current quality and viability of global bearing sources for the power transmission industry?

Custom PEEK Compounds have led to the development of transmission seals and thrust washers that offer lower wear, friction and temperature advantages.
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.
In the selection of lubricating greases for plastic worm gears, the user needs to know the influence of each grease constituent on the tribological performance in order to choose the appropriate lubricant. In this work, the effect of NLGI class, viscosity, base oil and thickener type are investigated separately regarding the efficiency and temperature close to the tribocontact. With the help of this contribution the user understands the effect of each parameter and learns about the potentially reachable efficiency and temperature ranges.
The first thing you see when you walk into Winzeler Gear is a pretty face. No, scratch that â” the face is beautiful. Streamlined with chiseled cheek bones, delicate yet bold and strong, a half dozen photos of the feminine face line the buildingâ™s entranceway, enclosed tastefully in simple black picture frames, beckoning you to come further in with its pleasant warmth, repelling you to turn and leave with its foreign presence in such a location.
During the past three decades there has been an evolution in the advancement and use of highly engineered plastics in bearing applications.
Regarding 3-D printing of gears and machine tools, etc. â” does plastic gearing have a future in 3-D printing/additive manufacturing?
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.
This article takes a look at alternative-material, non-metal bearings, and it turns out the first bearings of that type - wood, in this case, were the norm - not an alternative.
News From Around the Industry
Machine and equipment manufacturers today are feeling more pressure than ever to reduce costs without sacrificing machine performance â” a balancing act difficult to achieve. OEMs often overlook a simple solution that can have a positive, long-term impact on profitability for themselves and their customers, i.e. â” the elimination of bearing lubricant.
When it comes to a steel-gear mesh, there are several common standards and design rules on how to reduce noise emissions in the mesh. But if plastic gears are involved, this is no longer the case. The topic of this presentation is to highlight some of the differences between metal-and-plastic gear meshes, i.e. which design strategies can be stated as valid for metal as well as plastic and which are not?
Microgears for some types of medical technology need to be inexpensively mass produced. But at the same time, they need to be both precise and reliable, even though their design lifetime is relatively short. Here's how microgears were developed for blood glucose measuring devices, insulin pumps for diabetics and other very small devices.
While metal-to-plastic parts conversion actually began way back in the Fabulous Fifties, think toys, household products, etc., it is only in more recent years that plastic conversion has gained a firm foothold in the more strength- and lifetime-demanding applications such as aerospace, under-the-hood automotive, motors, valves, bearings and, as they say, much more.
Some gear geometries are more practical to produce than others. Since choices made early in the design process aff ect the ease and cost of fabrication, those who design gears would do well to consider molding and how molders operate, especially when they create precision gears.
