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.
The Industrial Internet of Things may be going off the deep end in connecting everything on the plant floor. Some machines, bearings, or conveyors simply donít need to be monitored -- even if they can be.
Wind turbines already are imposing structures that stretch high into the sky, but an engineering graduate student at the University of Notre Dame wants to make them even taller to reduce energy costs and improve efficiency.
