Tol-O-Matic SlideRite CR (corrosion resistant) gearboxes target packaging equipment with washdown requirements or operating environments where water or high relative humidity is present. The units consist of two 45-degree helical gears that mesh at right angles and achieve shaft speeds up to 1,200 rpm. The gearbox has corrosion-resistant electroless nickel-plated geared sleeves, keys and retaining rings as well as corrosion-resistant stainless steel bearings and races. A one-piece hard-coated aluminum case provides a built-in lubricant reservoir. The factory-lubricated units are leak-proof with floating operation in either direction on keyed shafts for long-term alignment. Operating temperature range is 0 to 300F. Recommended shaft materials are either alloy steel or stainless-steel for shafting with a minimum hardness of RC40 or transmission shafting grade such as 4140 or equivalent.

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.
