211 浸炭焼入れ歯車の残留応力と曲げ疲労強度に及ぼす側面浸炭焼入れの影響(OS1-3 伝動装置の基礎と応用)

Abstract

This paper presents a study on effect of gear-side case-hardening on residual stress and bending fatigue strength of case-hardened spur gears. The bending fatigue tests of case-hardened gears with different case depths and case-hardened parts (tooth surface and gear-side) were carried out, and the test results were examined on the basis of the residual stresses calculated by the three dimensional finite-element method (3D-FEM). Effects of the case depth, the residual stress and the gear-side case-hardening were determined to the considerable extent.
