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.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
