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.
There is currently much discussion around the term "platform," which may be preceded by the adjectives "mobile," "wearable," "medical," "healthcare," etc. However, regardless of the platform being discussed, they usually have one key aspect in common: They tend to be wireless. So, why is this one aspect so fairly universal? The answer is convenience.
Everyone has a MEMS story. For most of us it’s probably the airbag that saved our lives or the life of a loved one. Perhaps it’s the tire pressure sensor that alerted us about deflation before we were stranded alone on a dark muddy road.
Bioimimicry is not merely a helpful design tool -- it also encourages designers to think not only about how to solve design problems by imitating nature, but how to make the products, materials, and systems they design more ecologically sound and nature-friendly.
