A Review of Recent Advances in Design Optimization of Gearbox

Gearboxes find extensive use in a wide variety of fields. Over the years, a great deal of research has been devoted to prevention of gear failures and gear noise. Devising an optimal design is often considered as the most important stage in the development of a new gearbox. Similar to the varying requirements of different applications, the directions and method of gearbox design optimization are also varied. Usually, gear geometry optimization has a great influence on the strength and transmission error which is the excitation factor that affects the noise level. The main objective of this article is to summarize common optimization methods that have been recently studied by scholars. Moreover, a review of recent patents status quo, both domestic and overseas, is carried out.
