The proof of the reliability of a gear drive is now an additional requirement. In Europe, the acceptance authorities for wind turbines are requesting a system reliability proof from gearbox manufacturers. The AGMA committee reviewing the AGMA 6006 standard for wind turbines is considering adding a chapter about design for reliability. However, reliability considerations are not new; NASA, for example, was in the 1980s using reliability concepts for gear drives.
It was recently announced that the planet Mars has at least one thing in common with planet Earth: all good things come to an end. In this case, the good thing is the recently announced and documented (Feb. 12) demise of the Mars rover Opportunity.
Free vibration and dynamic operation testing of hybrid gears at NASA Glenn Spur Gear Fatigue Test Facility; hybrid gears are compared to their steel counterparts.
In 1941, the federal Aircraft Engine Research Laboratory set up shop in Cleveland, Ohio. This year, and several name changes later, what is now the NASA Glenn Research Center celebrates its 75th anniversary. As part of the year-long festivities, Glennâ™s adjunct Lewis Field main campus will be open to the public May 21 and 22, and Plum Brook Station in Sandusky, Ohio will hold its open house June 11 and 12.
Thereâ™s nothing quite as satisfying as scoring a goal. Here at Power Transmission Engineering, our goal is to provide you with as much relevant educational and technical material as possible, and every issue we strive to cover the subjects of power transmission and motion control from as many different angles as possible, so that no matter your job title, and no matter your industry, if gears, bearings, motors and related components are important to you, weâ™ve got you covered.
The performance of high-speed helical geartrains is of particular importance for tiltrotor aircraft drive systems. These drive systems are used to provide speed reduction/torque multiplication from the gas turbine output shaft and provide the necessary offset between these parallel shafts in the aircraft. Four different design configurations have been tested in the NASA Glenn Research Center, High-Speed Helical Geartrain Test Facility. The design configurations included the current aircraft design, current design with isotropic superfinished gear surfaces, double-helical design (inward and outward pumping), increased pitch (finer teeth), and an increased helix angle. All designs were tested at multiple input shaft speeds (up to 15,000 rpm) and applied power (up to 5,000 hp). Also two lubrication, system-related, variables were tested: oil inlet temperature (160â“250° F) and lubricating jet pressure (60â“80 psig). Experimental data recorded from these tests included power loss of the helical system under study, the temperature increase of the lubricant from inlet to outlet of the drive system and fling-off temperatures (radially and axially). Also, all gear systems were tested with and without shrouds around the gears.
Rosetta Mission mixes with Maxon, Kim K for one unforgettable photo
He was out. Nine years ago, Ross Rivard left the coupling industry for the shimmering new world of luxury automotive components at Lacks Enterprises, where he was immediately enveloped by platinum trim systems and chrome composite wheels. It was glitz and glam and as sparkly clean as the fresh-fromthe-dealership cars his products were embellished onto.

NASA launches Third Rock Radio.
Dust, soil broken rock and other related materials that blanket planetary surfacesâ”known as regolithâ”have great potential to contribute to space observation research, but the physical properties of lunar regolith are unique and very difficult to excavate from a technical perspective. A group of students at the Missouri University of Science and Technology, dubbed the Lunar Miners, decided to step up to the plateâ”that is, by entering the 2008 NASA Regolith Excavation Challenge.
