Abstract
The effort of gear noise reduction has traditionally focused on minimizing transmission error. On the other hand, gears vibration characteristics are also known to influence gear noise strongly. With the thin helical gears, therefore, the entire gear noise mechanism is clarified quantitatively by experimental analysis, and a dominant factor is specified. The analysis has shown that meshing force is the most significant factor. Thus, innovative gear structure has been devised, which aggressively controls meshing force characteristics like a dynamic vibration reducer. Redesigned gears have successfully improved gear noise. These experimental technologies and design methods can be applied to general gear noise problem in order to conduct optimization.
