2 Hybrid Gear Preliminary Results: Application of Composites to Dynamic Mechanical Components (May 2013)

Composite spur gears were designed, fabricated and tested at NASA Glenn Research Center. The composite web was bonded only to the inner and outer hexagonal features that were machined from an initially all-metallic aerospace quality spur gear. The hybrid gear was tested against an all-steel gear and against a mating hybrid gear. Initial results indicate that this type of hybrid design may have a dramatic effect on drive system weight without sacrificing strength.

3 Green Gravy (January/February 2009)

Step right up! Get your U.S. government gravy here! We’re the U.S. Treasury Department’s Troubled Asset Relief Program, and we’re printing money like we’re—well—the U.S. reasury. If you’ve got trouble, then get your assets in line!

4 Hybrid, Alternative Drivetrains Take Center Stage at CTI Symposium (May 2010)

As the automotive industry continues to reinvent itself, new transmission technologies are at the forefront of this effort, and there is a whirlwind of new developments being detailed at the German Car Training Institute’s Automotive Transmissions and Drive Trains Symposium North America.

5 Noise Reduction in an EV Hub Drive Using a Full Test and Simulation Methodology (May 2016)

With the ongoing push towards electric vehicles (EVs), there is likely to be increasing focus on the noise impact of the gearing required for the transmission of power from the (high-speed) electric motor to the road. Understanding automotive noise, vibration and harshness (NVH) and methodologies for total in-vehicle noise presupposes relatively large, internal combustion (IC) contributions, compared to gear noise. Further, it may be advantageous to run the electric motors at significantly higher rotational speed than conventional automotive IC engines, sending geartrains into yet higher speed ranges. Thus the move to EV or hybrid electric vehicles (HEVs) places greater or different demands on geartrain noise. This work combines both a traditional NVH approach (in-vehicle and rig noise, waterfall plots, Campbell diagrams and Fourier analysis) — with highly detailed transmission error measurement and simulation of the complete drivetrain — to fully understand noise sources within an EV hub drive. A detailed methodology is presented, combining both a full series of tests and advanced simulation to troubleshoot and optimize an EV hub drive for noise reduction.

6 Future Demands Next Generation of Standards and Practices in Gear Industry (May 2010)

Gear manufacturers are moving into an era that will see changes in both engineering practices and industry standards as new end-products evolve. Within the traditional automotive industry, carbon emission reduction legislation will drive the need for higher levels of efficiency and growth in electric and hybrid vehicles. Meanwhile, the fast growing market of wind turbines is already opening up a whole new area of potential for gearbox manufacturers, but this industry is one that will demand reliability, high levels of engineering excellence and precision manufacturing.
