Experimental and Computational Methods for Strength Analyses of Gears

Gears are machine elements used in most engineering applications, mainly in the automotive and aerospace industries.

When designing gear drives, the available standardised procedures are usually used for that purpose.

However, the available computational methods are also often applied to obtain the load capacity of gears considering different fatigue design approaches (i.e. the stress-life approach, the strain-life approach and the fatigue crack growth approach).

This book consists of five chapters. The first chapter introduces the reader to the fundamental magnitudes of gear drives concerning cylindrical gear pairs, bevel gear pairs, and worm gear pairs.

The second chapter explains the theoretical background of the load capacity of gears; surface pitting load capacity and tooth root load capacity are described in detail.

The third chapter focuses on the strength analyses of metal gears.

Chapters four and five describe the strength analyses of sintered and polymer gears, including some typical practical examples.
