Gear Materials, Properties, and Manufacture

Gear Materials, Properties, and Manufacture explains how material-related properties and operating conditions affect the lifetime and performance of gears and the ways in which they fail. It begins with a review of the basic design and configuration of gears and related engineering considerations. It then examines the effect of friction and wear and the role of lubrication in gear failures. It explains how to calculate lubricant film thickness, defines lubrication regimes, and presents guidelines for selecting and applying lubricants for specific applications. The chapters that follow cover gear materials and manufacturing methods, providing details on metals and plastics and processes such as casting and forging, powder metallurgy, injection molding, machining, grinding, finishing, and carburizing and nitriding treatments. The final chapters discuss the types and causes of gear failures and the steps involved in failure analysis. They also explain how to assess fatigue damage and estimate remaining service life and describe the tests that are used to evaluate the durability of gears under load.
