Top 10 Reasons You Should Go to Gear Expo 2009

Let's face it. It's been a bummer of a summer economically speaking. Here's why you should still go to the show.

CFD Technology for Rotorcraft Gearbox Windage Aerodynamics Simulation

A computational fluid dynamics (CFD) method is adapted, validated and applied to spinning gear systems with emphasis on predicting windage losses. Several spur gears and a disc are studied. The CFD simulations return good agreement with measured windage power loss.

Effects of Axle Deflection and Tooth Flank Modification on Hypoid Gear Stress Distribution and Contact Fatigue Life

As is well known in involute gearing, “perfect” involute gears never work perfectly in the real world. Flank modifications are often made to overcome the influences of errors coming from manufacturing and assembly processes as well as deflections of the system. The same discipline applies to hypoid gears.

Steadfast and Streamlined: Can Lean Soften the Economic Blow

Two high-volume gear production cells grace the shop floor at Delta Research Corporation in Livonia, Michigan. Thanks to lean manufacturing, these cells have never shipped a defective part to a customer since they were developed over three years ago.

Gear Expo 2009 - The Show of Shows for All Things Gearing

As Gear Expo 2009 approaches (Sept. 15–17), the show finds itself in an “It was the best of times, it was the worst of times” mindset.

Candy Gears - Where Mesh Meets Marshmallow

On the production floor at Knechtel, food scientists, chemists and engineers take part in Willy Wonka-like experiments in search of the perfect piece of candy.
