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.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
