MOTION CONTROL: Servometer®/PMG LLC precision, electrodeposited, nickel alloy, bellows-type, flexible shaft couplings provide torque capabilities from 2 oz-inch (1.4 Ncm) to 20 lb-ft (27 Nm), for shaft sizes ranging from .090 to 1 inch. Because of their flexibility, the low torque couplings can handle angular misalignment up to 31 degrees or parallel misalignments (shafts parallel but offset) up to .076 inch. In general, as flexibility increases, torque capacity decreases. For attachment to shafts, standard set screw hub, split hub with clamping collar or integral clamp hub styles are available. Unique characteristics of Servometer bellows couplings include zero backlash; vibration damping capability; zero cyclic speed variation during 360-degree rotation; very low elastic windup, due to torsional rigidity; and low side thrust on bearings because of lateral flexibility. Bellows couplings are for use in critical applications such as resolvers, encoders, servos, motion control devices and computers.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
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.
