Abstract
High strength transmission gears have been developed for use in the final gear set of front-wheel-drive vehicles. The steel used as the gear material has a higher molybdenum content, allowing more austenite to be retained following carburizing than is possible with chromium steel. As a result, the steel can be subjected to higher intensity shot peening by using harder peening particles which are projected by an air-nozzle peening system. With this procedure, the fatigue strength of the gears can be increased 1.6 times over that of conventional gears.
