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.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
