Looking at a Gear Cube XXL, you can't help but think about a Rubik's Cube. Both are 3x3 puzzle cubes with brightly colored pieces. Moreover, both are sold commercially as toys.

In planetary gear systems of high power density and high gear ratio, helical gears create undesirable tilting moments on the planet gears; therefore, spur gears are still preferred for planetary gears -- a special challenge with respect to noise. Specifically, the different behavior of planetary gears with sequential and symmetric gear mesh is explained in this paper.

Condition Monitoring Technology Evolves for Gear Drives, Gearmotors and Gearboxes. Here's a look at what some leading manufacturers are offering.

This sidebar examines some of the latest E-Mobility products and technologies from companies like Schaeffler, Eaton and Dana. Check out the full ar...

This work explains why some idler sets produce so much gear whine. While transmission error must be managed, there is another tool in the gear whine management toolbox.

You might not expect a humble cylinder to garner more attention than a luxury boat or a giant, shiny stage prop, and yet thatâ??s just what happened in Michigan's latest contest celebrating local manufacturersâ?? contributions.

Special advertising section focuses on motion control.

As concerns surrounding the environmental impact of fossil fuels continue to grow, so does the need to produce vehicles with higher overall efficiency. The importance of enhanced vehicles has spurred drivetrain component manufacturers to study every aspect of efficiency loss in their products. The gearbox is a key contributor to the overall drivetrain efficiency.

Key technical drivers which can be addressed by advanced PM manufacturing technologies are, for example, the need for system downsizing in transmissions and differentials, the need for developing systems with higher power density and the strong NVH (Noise Vibration Harshness) requirements - especially for electrified transmissions or e-axle solutions.
