Abstract
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 mn = 1.5, 5, and 10 mm are examined in pulsator test rigs. Additionally, gear running tests in the FZG back-to-back gear test rigs for the gear size mn = 1.5 are performed.
