Rotational Vibration of a Helical Gear Pair Having Tooth Surface Deviation during Transmission of Light Load. 1st Report. An Analysis of Approach between Gear Teeth with Surface Deviation.

Abstract

A detailed description of elastic behavior due to contact is necessary for the analysis of vibrational behavior of a pair of helical gears having a tooth flank deviation which yields partial face contact under light load conditions. This paper shows how we can obtain the relationship between load distribution and the compressive deformation of meshing surfaces assigning the tooth contact pattern with geometry of two surfaces. Tooth surface contact is approximated by the contact between a finite-length cylinder surface whose radius varies along its center axis and a plane with the same width. Our results have been verified by experiment.
