Contact Stress Analysis for Helical Gear with 3-Dimensional Finite Element Method. The Profile Correction Amount to Reduce the PV Factor of Helical Gear Teeth.

Kousaku OHNO, Naoyuki TANAKA

Abstract

The contact stress of helical gears is calculated with 3-dimensional finite element method. The relation between the contact stress and the profile correction amount is investigated and the foliowings were obtained; (i) The tooth stiffness of helical gears is able to be estimated with that of virtual spur gears. (ii) The stress decrease at the tooth tip results in partial increase of the stress at the correction starting point. (iii) About 1.5 times the tooth deflection amount of the virtual spur gear is reasonable for the profile correction amount of helical gear.
