THK's newest actuator has 200 percent higher load capacity than the original Type GL, using two caged ball type LM guides (Type SSR and Type SHS), and four raceways, instead of the standard two. It goes up to twice as fast as conventional types (at 5m/sec, and accelerations over 5Gs), due to the lack of metal-to-metal contact, plus tests show noise levels up to 15 dBA lower. It lubricates itself with gaps between rolling elements that retain grease. An aluminum extrusion base makes for a lightweight, strong construction. It comes with metric mounting holes, but inch mounting holes are available for the same price. Ball screw and belt-driven versions are available, the former with a QZ lubricator. They come in standard lengths of up to 3m, with custom lengths available. Accessories include bellows covers and a LaCS Scraper.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
