Low friction and long life on a lubrication-free pivot
This is a patented pivot that doesn't use lubrication, so it will work in a vacuum or super-clean area, and with no rubbing surfaces, it will also work in an unclean atmosphere without the problems of fretting or friction. With a radial design, the pivot has low hysteresis, center shift and thermal drift. The pivot uses springs with low cyclic stress, giving it an indefinite life, perfect for those critical, hard-to-get-at areas. It's often used in oscillating mirrors, lever linkages, instrument nulling, weighing machines, bearing preloading, gimbal rings, mirror positioning, scanners, fuel controls and pressure and vibration transducers. It has cantilever or double-ended support configuration.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
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.
