Investigations on the tooth root bending strength and the fatigue fracture characteristics of case-carburized and shot-peened gears of different sizes

This paper contains data of the research project FVA 293 III by Schurer et al. and investigates the tooth root bending strength and the fatigue fracture characteristics of case-carburized and shot-peened gears of different sizes. The investigated carburized and shot-peened gears are made out of high-purity steel batches of the materials 20MnCr5 and 18CrNiMo7-6. Three different gear sizes with the normal modules m n = 1.5, 5, and 10 mm are...
