Tol-O-Matic has introduced line of rod screw actuators that is noteworthy for the breadth of standard sizes available, including metric, English, and ISO sizing, says Derek Wise, project engineer. Six different body sizes are available, ranging from 3/4 to 4 inches and five different lead screw diameters, from 3/8 to 1/2 inch with a solid or ball nut configuration. Any stroke length is available up to an actuator's maximum capacity, with thrust capabilities ranging from 70 to 4,200 lbs.
"With other lines that are more limited, the engineer often has to compromise on the stroke size. For example, he or she may want a 13-inch-stroke but have to settle for a 16-inch-stroke," says Wise. "Obviously, they will be paying for capabilities they don't need, and they'll have to oversize their design."
The actuator features an extruded body, allowing for easy four-sided mounting and an internal guide bearing design that provides rigid support of the thrust rod at the full stroke length and maximum surface area for extended life. "We've got a lot of interest going on in the medical industry today," says Wise. "That's primarily because of the accuracy of the product."
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.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
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.
