ATLANTA Drive Systems Inc. has expanded its range of servo worm reducers, building a high-torque, economy and basic version to go with the existing high-precision reducer. The high-torque model has 150 percent of the torque capacity of ordinary servo-worm reducers, and a backlash level of less than 1 arc-minute. It has a redesigned output for higher bearing capacity, plus an option for ISO 9409 flanged connections. The economy model has the same torque capacity of an ordinary servo-worm reducer, with a less than 6 arc-minutes backlash level. The basic version has 90 percent of an ordinary servo-worm reducer, and a backlash level of less than 12 arc-minutes. There is a range of motor couplings and mounting flanges available for almost any servo motor, and the hollow bore output works well with output shafts, pinion shafts or other drive elements.
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.
