After more than two years of COVID isolation, it feels good to be getting out of our bunkers and interacting with people again. Last month, I had the great pleasure of attending the AGMA Annual Meeting, where executives from member companies got together in person for the first time since 2019. The 2020 meeting was canceled at the last minute due to COVID. Last year’s meeting was held virtually, with an electronic meeting room and videoconference presentations. But this year felt like a return to normal.
Tool-X is a nanofluid that changes the characteristics of existing metalworking fluids by ‘manipulating’ speeds, feeds and metal removal rates using nanotechnology. The science behind Tool-X can potentially change metal cutting dynamics, improve surface finishes and extend tool life. The backstory of this technology is just as fascinating as its production results.
The objective of this paper is to improve the methodology for determining the tooth flank temperature. Two methods are proposed for assessing scuffing risk when applying AGMA 925 for high-speed gears. Both methods provide similar results.
When it comes to noise, vibration and harshness (NVH), I’m reminded of that dog-van scene from Dumb and Dumber where Jim Carrey says, “Want to hear the most annoying sound in the world?” and then proceeds to emit an astonishingly awful noise. Annoying as NVH may be, it’s a key metric in drive-system development for e-mobility, and the careful design and manufacture of gears are crucial to minimizing NVH as tolerance variations can result in large differences between nominally identical components.
It wasn’t long ago that cylindrical gear chamfering and deburring was almost an afterthought. Now the process ranks as high in importance as hobbing, shaping and grinding. Seemingly every gear manufacturer, particularly those developing transmission gears for e-drive applications, recognizes that anything less than a flawless tooth flank can result in premature transmission failure, less-than-optimal efficiency, and unacceptable noise. Thus, generating a chamfer to precise customer specifications is critical to minimize the potential for sharp, brittle edges after heat treat; avoid edge load situations in the gearbox; and eliminate excessive stock and hardened burrs in the tooth flank prior to the hard finishing operations (conditions which can greatly diminish tool life).
Manufacturers need to measure and quantify the causes of unproductive time so they can optimize their efficiency. Machine Monitoring from Seco provides them with the data-driven knowledge they need to not only manage production efficiency, but also increase both output volume and product quality.
Southern Gear has added two rebuilt Gleason No. 102 Generators to its production capabilities to meet growing demand for smaller, high-precision straight bevel gears produced with the Coniflex process.
Jorgensen Conveyor and Filtration Solutions has introduced its new FlexFiltration line that also includes the company’s new Flex G Series of modular filtration systems. The new cost-effective systems feature pre-engineered modules that ensure fast, easy and flexible filtration system configurations for practically any filtering application.
The automotive industry is evolving. The trend toward more electromobility is also changing the way cars are being manufactured. In some cases, this has a serious impact, not only on automakers themselves, but also on suppliers. Jürgen Hechler, Global Application Engineering Leader at 3M, is nevertheless confident: "We expect the demand for high-precision abrasives to continue to grow, despite the discussion about electromobility." Among other things, 3M supplies the automotive industry with abrasives for machining gears and shafts.
AGMA is happy to announce the publication of two new documents: AGMA 925-B22, Effect of Tribology and Lubrication on Gear Surface Distress, written by a subcommittee of the AGMA Helical Gear Rating Committee, and, AGMA 943-A22, Tolerances for Spur and Helical Racks, written by the AGMA Gear Accuracy Committee.
Saint-Gobain Abrasives has introduced its new Norton Abrasive Process Solutions (APS) Program which was established to help customers determine the optimal grinding or finishing solution for the application at hand, ranging from simple to complex, off-hand or automated, and for metal fabrication, production grinding and virtually any abrasives operation.
As a sustainability advocate and supporter of global sustainability goals, Sandvik Coromant has developed a set of internal goals called Make the Shift to set a new industry standard and raise the bar for sustainable business.
Eaton's Vehicle Group is celebrating 50 years of MLocker differential production. The mechanical locking differential provides drivers with best-in-class traction without the need for pushbuttons, shift knobs, or other driver intervention, and is applicable to vehicles with both internal combustion engines and electrified vehicles (EVs).
