A Review of Gear optimization Methods

Gears are the important components of almost every machines used in industrial environment for that Searching for best gear is a very hard problem and Optimization theory is one of the oldest branches of Mathematics. Gear optimization can be divided into two categories, namely, single gear pair or Gear train optimization. The problem of gear pairs or gear design optimization is difficult to solve because it involves multiple objectives and large number of variables. Therefore a reliable and robust optimization technique will be helpful in obtaining optimal solution for the problems. This review is intended to showcase variety of methods used to find the exact solution of elementary problems. Finding an alternative with the most cost effective or highest achievable performance under the given constraints by maximizing desired factors and minimizing undesired ones.
