AGMA 06FTM11 PDF

This paper is an analytical study of tooth failure in gearing having small numbers of teeth. For the analysis, tooth contact stresses and combined shear stresses are investigated. The study is based on gear tooth loading, accounting for load variations with time and other gear parameters in various phases of tooth meshing. The contact and shear stresses are by simultaneous: (a) contact stresses together with (b) stresses caused by the pinion and gear sliding. While developed for use in gearing with low numbers of teeth, the method can be used for computation of stresses in gearing having more teeth. The results of the research could be used with AGMA 908-B89 for gears having less than 12 teeth.
