Belt-Driven Actuators

By Design News Staff -- Design News, September 4, 2006

High speeds and no maintenance

Del-Tron's newest actuators run at speeds up to 5.1 m/sec, and without lubrication or maintenance under normal conditions. They have travel lengths up to 6m with a repeatability of ±0.025 mm and a linear accuracy of ±0.083 mm/m. They come with a steel-reinforced polyurethane belt, and the drive features Del-Tron's own extrusion design. The planetary gearheads can handle input speeds up to 10,000 rpm and have high output loads. They use zero helix angle gears, not helical gears and large, sealed, deep-groove ball bearings support the output shaft. The actuators come with a choice of steel concave rollers on chrome-plated steel rails, a plastic-coated needle bearing assembly, or plastic bearings on aluminum rails. The steel bearings come with lifetime lubrication, while the plastic bearings need no lubrication at all.

Light Matters: A High-Performance, "No-Compromise" Solid State Lamp?
First, let's define "no-compromise". In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package, and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible.
