Abstract

Abstract

Both tooth flank contact fatigue and tooth bending fatigue with ion-nitrogen case-hardening 25Cr2MoV steel gears were investigated. The conclusions of distributing rules both their fatigue lives and fatigue strength were obtained were investigated.The R-S-N curve equations,both limiting stress of tooth flank contact fatigue and limiting stress value of tooth bending fatigue under various reliabilities were also evaluated.
