This coupling variant was designed for machining spindles, flying shears and other applications with shock loads that can't have any backlash. The couplings have conical sleeve hubs for keyless torque transmission in highly dynamic, reciprocating loads. They work well with high-speed applications with frequent load reversals or stops, with no backlash characteristics and a high clamping force and concentricity. They have a positive stop on the conical ring, which ensures clamp screws will tighten to the right torque during installation, but the ring can't be tightened more than needed, so they are much easier to remove from shafting. Sizes range from 10 Nm (89 lbs-inch) to 2150 Nm (19027 lbs-inch), and can take English or metric bores with 6- to 80-mm diameters.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
