Precision Gearing

High Speed. High Quality.

From Concept Drawing to Flight Safe Operation.

Timken Aerospace Drive Systems (ADS) has manufactured some of the most complex gears and ancillary gear products used in the toughest rotorcraft applications in the world. This suite of products merges around a single, driving concept: attention to detail.

Capable of manufacturing gears up to AGMA 15 quality, ADS uses only the highest quality aerospace materials. These include either carburized 9310, or Pyrowear® X-53 and nitrided Nitralloy N, or 4340 steels. Further, because ADS has its own in-house heat treatment and vacuum carburizing capability (including the design of quench dies) as well as a metallurgy laboratory, ADS can control each aspect of the production process to guarantee adherence to the exacting specifications of its customers.

This ability to maintain absolute control of the material – from microhardness and microstructure verification, to assessing carbon potential, to physically sampling sections of the gears – uniquely positions ADS to deliver the highest quality aerospace gearing available.

Additionally, each gear undergoes a rigorous inspection and metrological process to create a permanent record of all dimensions and performance characteristics.

For example, we compare spiral bevel gears to master gear data and archive tape transfers showing the approved contact pattern between the gears we manufacture and customers’ master gears. Attention to detail.

High precision gearing products made by ADS:

  • Electron Beam (EB) welded assemblies
  • Splines (straight and crowned)
  • Curvic couplings
  • Spur gears
  • Single helicals
  • Double helicals
  • Spiral bevels
