Abstract
Gear is a handy power transmission machine element, and is widely used in industrial machineries. However, it yields vibration and noise with the rotation. Various researches (1) (3) have been made on this problem so far. In the past research, it is said that the vibration of the meshing frequency was caused by the change of equivalent stiffness of meshing teeth. However, it is observed experimentally to receive the influence of the lubrication. Moreover, when considering the lateral-torsion coupled vibration, the vibration of power transmitting direction and teeth slide direction are said to be independent while slight interaction is observed experimentally. In this study, we experimentally confirm the phenomenon, and investigate the cause.
