The optimum carburized and hardened case depth for each gear failure mode is different and must be defined at different locations on the gear tooth. Current gear rating standards do not fully explain the different failure modes and do not clearly define the different locations that must be considered.

An economical modernization program gives Designatronics' tried-and-true Gleason No. 102 Coniflex generators a new lease on life for fast, reliable production of smaller precision straight bevel gears.

Lubrication - as it pertains to the gear industry - is a rather large universe, much, much more than the old double-entendre, "the squeaky wheel gets the grease."

When I started Gear Technology more than 35 years ago, my intention was to create something of lasting value for the gear industry. It was a way of giving back to the industry that had been so good to me and my family.

Geoff Ashcroft’s wonderful account of his odyssey from the United Kingdom through India and on to the United States illustrates just how different ...

The oil-off (also known as loss-of-lubrication or oil-out) performance evaluation of gears is of significant interest to the Department of Defense and various rotorcraft manufacturers, so that the aircraft can safely land in an accidental loss-of-lubricant situation. However, unlike typical gear failure modes such as pitting or bending fatigue where early detection is possible, gear failure in an oil-off situation is very rapid and likely catastrophic. Failures rapidly result in the loss of torque transmission and the inability to control the aircraft.

Finding capable, dependable machinists is one of the great challenges of modern manufacturing. Most gear manufacturers we talk to would hire more machine operators - if only they could find them. They lament the fact that their workforce is getting older and grayer, and they don't know what to do.
