MOTION CONTROL:Ruland now offers miniature rigid couplings with bore sizes as small as 3 mm. Miniature rigid couplings are suitable for micro component applications where misalignment is neither present nor desired, including connecting line-shafts, attaching a motor to a gearbox, and servo applications. Offering high torque capacity, stiffness and zero backlash, Ruland’s rigid couplings are increasingly being used in precision motion control applications where misalignment is tightly controlled.Ruland’s miniature rigid couplings are available in aluminum, carbon steel or stainless steel. The bores of the couplings are precision honed in the manufacturing process, assuring tolerances of +.05/-.00 mm. This enhances the overall performance of the couplings, especially important for applications that require strict control of shaft alignment and greater torque transmission ability. All rigid couplings from Ruland have Nypatch socket head cap screws for increased performance and reliability. This coating is designed to reduce screw vibration, which can cause the screws to loosen and torque transmission ability to diminish during the course of normal use.
Rigid couplings are available in one-piece clamp style, two-piece clamp style and set screw style versions, with or without keyways. A large number of standard sizes are available in straight and step bore combinations to fit shafts ranging from 1/8 to 2 inch in the inch dimension series and from 3 to 50 mm in the metric dimension series. Inch to metric conversion couplings are also available by special order.
Rigid couplings are part of Ruland’s product line which also includes shaft collars and five types of zero-backlash motion control couplings including beam couplings, bellows couplings, oldham couplings, jaw couplings and miniature disc couplings.
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.
