FLUID POWER: New CD Couplings® from Zero-Max provide the ideal combination of high dynamic load capacity and high torsional stiffness to ensure reliable system operation in fixed displacement hydraulic pumps driven by servo motors. They are designed so the working part is made of a composite material. The composite disc design withstands the punishment and stress of a servo motor. CD Couplings® are available in single and double flex aluminum hub models with or without keyways. The single flex models have a torque capacity range from 40 to 1,436 Nm and beyond with speed ratings from 4,400 to 17,000 rpm. All CD Couplings are environmentally friendly and manufactured of RoHS-compliant materials.
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.
