MOTION CONTROL: Servometer®/PMG LLC precision, electrodeposited, nickel alloy, bellows-type, flexible shaft couplings provide torque capabilities from 2 oz-inch (1.4 Ncm) to 20 lb-ft (27 Nm), for shaft sizes ranging from .090 to 1 inch. Because of their flexibility, the low torque couplings can handle angular misalignment up to 31 degrees or parallel misalignments (shafts parallel but offset) up to .076 inch. In general, as flexibility increases, torque capacity decreases. For attachment to shafts, standard set screw hub, split hub with clamping collar or integral clamp hub styles are available. Unique characteristics of Servometer bellows couplings include zero backlash; vibration damping capability; zero cyclic speed variation during 360-degree rotation; very low elastic windup, due to torsional rigidity; and low side thrust on bearings because of lateral flexibility. Bellows couplings are for use in critical applications such as resolvers, encoders, servos, motion control devices and computers.
Enabling the Future is designing prosthetic appendages modeled more like superhero arms and hands than your average static artificial limbs. And they’re doing it through a website and grassroots movement inspired by two men’s design and creation in 2012 of a metal prosthetic for a child in South Africa.
In order to keep an enterprise truly safe from hackers, cyber security has to go all the way down to the device level. Icon Labs is making the point that security has to be built into device components.
Three days after NASA's MAVEN probe reached Mars, India's Mangalyaan probe went into orbit around the red planet. India's first interplanetary mission, and the first successful Mars probe launched by an Asian nation, has a total project cost of nearly $600 million less than MAVEN's.
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.
