Abstract

Abstract In the framework of a research project, the tooth root bending strength of high-strength gears is investigated. The most common type of failure encountered with these shot-peened, case-hardened gears is tooth root breakage caused by a crack initiation below the surface at a non-metallic inclusion (fisheye failure). However, it is well known that case-hardening depth and quenching grain size can have a great influence on a gear’s load carrying capacity. To ensure that this research project solely investigates the influence of non-metallic inclusions, any cross-influences must be excluded or minimized, or at least known. However, in the case of such ultra-clean gear steels, no recommendations or investigations of the influence of case-hardening on material properties are currently available. Therefore, in the framework of this paper, extended investigations are conducted into the effects of different process steps during case-hardening on the resulting material properties of ultra-clean gear steels.

淬火过程中加热速率和浸泡温度对超净齿轮钢硬度和晶粒尺寸的影响
在某研究项目的框架下,对高强度齿轮的齿根弯曲强度进行了研究。这些喷丸淬火齿轮最常见的失效类型是由表面以下非金属夹杂物处的裂纹引发的齿根断裂(鱼眼失效)。然而,众所周知,淬火深度和淬火晶粒尺寸对齿轮的承载能力有很大的影响。为了确保本研究项目仅研究非金属夹杂物的影响,必须排除或最小化任何交叉影响,或至少知道。然而,在这种超清洁齿轮钢的情况下,目前还没有关于表面硬化对材料性能影响的建议或调查。因此,在本文的框架内,扩展的研究进行了不同的工艺步骤,在淬火过程中对所得的超净齿轮钢的材料性能的影响。
