MOTION CONTROL: An Ohio-based manufacturer of horse-drawn farming equipment predominately employed by Amish communities uses iglide® plastic plain bearings from igus® on a “crumbler” mechanism; used to crush clods of dirt during the tilling process. The bearings replaced a system of metal shafts and collars that required messy lubricants and frequent maintenance. iglide G300 bearings are used on each of the crumbler’s eight rolling elements. Grease fittings made the rollers susceptible to dirt build-up, which eventually led to the formation of a thick sludge as the tool sat idle between harvests. iglide bearings are lubrication-free and dirt- and dust-resistant. They are also unaffected by rain and any moisture from the soil because of their corrosion-resistant and low-moisture-absorption properties.
iglide plastic plain bearings are available in 28 different polymers. Every iglide bearing material possesses a number of special features, which makes it suitable for particular applications and requirements. iglide G300 bearings are cost-effective and can be paired with a number of different shafting materials. They are best for rotational and oscillating movements and low to average running speeds. They also possess a low coefficient of friction and high wear-resistance.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
