Rolling bearings are one of the most widely used components in industrial machinery. If
suitably mounted, loaded, lubricated and isolated from contamination, rolling contact fatigue …

This paper presents a review of existing theory and practice relating to main bearings for
wind turbines. The main bearing performs the critical role of supporting the turbine rotor, with …

随着航空, 风电, 重载车辆等装备对齿轮传动功率密度, 承载能力, 疲劳寿命要求的提高,
以微点蚀, 点蚀, 深层齿面断裂等多种形式存在的齿轮接触疲劳失效成为限制现代齿轮及装备 …

Modern bearing steels are critically important ultra-high strength structural materials used in
a multitude of industrial systems, and subject to the highest loading conditions for billions of …

Non-metallic inclusions such as sulfides and oxides are byproducts of the bearing steel
manufacturing process. Stress concentrations due to such inclusions can originate cracks …

The crack propagation in bearing steel with a non-metallic inclusion is analyzed by Voronoi
finite element method. The load applied on the Voronoi finite element model is obtained by …

The continuing improvement on the power density, loading capacity and fatigue life of gear
transmissions used in industrial machineries such as in the aerospace, wind turbine and …

This paper focuses on the crack nucleation and crack propagation induced by a cluster of
carbides. The morphology of the carbides is extracted from scanning electron microscope …

The fatigue failures of gears have great influence on lifetime and reliabilities of mechanical
transmissions. Initial residual stress (IRS) induced in the manufacturing process, together …

Fatigue failure in rolling element bearings (REBs) is a highly stochastic process influenced
by the anisotropy of bearing material and the coupled elastohydrodynamic lubrication (EHL) …
