HCR gearing geometry optimization by using of generalized particle swarm algorithm

Abstract

© Springer International Publishing Switzerland 2014. Pitting and temperature scuffing evidenced by damage to teeth flanks of gears are the most important problems needing to be solved in the process of gearing design and calculation. According to current valid standards, such calculations can be resolved with a high level of reliability for all the usual gearing types. However, suitable calculations for High Contact Ratio (HCR) gears have not been adequately researched to date. It has been identified that in HCR gears some different process of scuffing and pitting formation occurs during the gear’s operation. Therefore it is actual to deal with optimization of HCR gearing just from these kinds of teeth flanks damages. In article, the authors describe a new method for finding optimal solutions for geometrical parameters h*a1, h*a2 and x1, using a Generalized Particle Swarm Optimization Algorithm for both above mentioned optimization tasks.
