High positional accuracy in a zero-backlash gearhead
Built for OEM robotic applications, the SHD Gearhead Size 14 has a 1.5 arc-min positional accuracy and ±5 arc-sec repeatability. It has a high precision harmonic drive gearing and high-capacity cross roller bearing, with a rated torque of 33 inches-lb and a maximum torque of 310 inches-lb. It has an outer diameter of 70 mm, is only 17 mm long, and comes in 50:1 and 100:1 gear ratios. It has necessary motion control components like the harmonic drive gear and the cross roller bearing, which allows it to be incorporated into the machine housing.
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.
