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.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
A group of researchers at the Seoul National University have discovered a way to take material from cigarette butts and turn it into a carbon-based material that’s ideal for storing energy and creating a powerful supercapacitor.
