The trend in
industry to process more material faster and more efficiently calls for a
high-torque, high-misalignment, low-inertia servo coupling, with minimal compromise
to torsional stiffness. Stainless-steel bellows couplings have the highest
torsional stiffness of commercially available flexible couplings, making them
the best choice for aggressive servo-driven applications. But in cases where
the two shafts to be connected are mounted to different bearing surfaces, it
can be difficult to maintain the precise alignment tolerances normally
special, high-stiffness bellows and new, high-strength connection method, R+W's
handles an average of 2.6 times the traditional torque rating at a given
outside diameter, and an average of 2.9 times more lateral misalignment,
opening up the benefits of precision bellows couplings to a whole new segment
of machine design and servo motion control.
diameters ranging from 15 to 60 mm and torque ratings from 20 to 1,000Nm, the
BKZ range is available in four sizes, with a variety of materials, finishes and
the optional self-opening clamp system.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
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.
