Installation on left shows locking ring integrated with both inner and outer bearing rings.
The patented Locking Ring is designed to be a self-locking, vibration resistant installation for mounting ball bearings. For plane housing bores, the ring, which is threaded around the bearing's outer ring, has sawtooth-shaped asymmetrical threads which form a continuous helical inclined surface across the internal length of the ring. Using a "spanner" wrench, locking action is due to the wedging between the surfaces of the tapers on the inside of the ring against similar threads on the bearing's outer ring—the slotted locking ring then expands, fixing the bearing to the housing. Axial and torque loads are transmitted by clamping pressure and friction. A Locking Ring may also be used to clamp the bearing's inner race to the shaft on which it mounts. Advantages include saving installation/removal time and money, being self-centering and dynamically balanced, and relaxation of housing hole and shaft diameter tolerances. Alternatively, the asymmetric threads could be cut into the housing bore and mounting shaft, eliminating need for the intervening Locking Ring.
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
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?
