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.

One of our goals at Power Transmission Engineering is to help you understand, identify and select the best technology for your mechanical power transmission or motion control applications. With every project, you have to decide which components to use, and which suppliers, based on functionality, quality and price. We aim to help you make those decisions informed by providing the latest information on current technology, especially when it comes to mechanical components.

Heavy industry. The phrase conjures images of mines and steel mills, of huge caverns underground, of cavern-like factories, of oldline companies operating heavy-duty machines for hightorque work. That's the image of heavy industry. Today, though, there's also another image. It's of an operator walking a steel mill's floor, looking at his smartphone or his tablet.
The theme of this issue is integration. Mechanical components are being developed with embedded sensors. The components are talking to each other, sending information to the cloud and producing terabytes of big data to help manufacturers better understand their processes, predict problems and control costs.
This issue Engineering Showcase features some of the leading suppliers of couplings.
Custom PEEK Compounds have led to the development of transmission seals and thrust washers that offer lower wear, friction and temperature advantages.
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?
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.
Regarding 3-D printing of gears and machine tools, etc. âÂ€” does plastic gearing have a future in 3-D printing/additive manufacturing?
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.
igus bearings solve undersea issues for the marine vehicle industry.

The first thing you see when you walk into Winzeler Gear is a pretty face. No, scratch that âÂ€” the face is beautiful. Streamlined with chiseled cheek bones, delicate yet bold and strong, a half dozen photos of the feminine face line the buildingâÂ€™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.
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.
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.
Machine and equipment manufacturers today are feeling more pressure than ever to reduce costs without sacrificing machine performance âÂ€” 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. âÂ€” the elimination of bearing lubricant.
News From Around the Industry
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.
