中文摘要
在该项目的框架内,将展示如何通过使用合适的固体和对配对体进行适当的表面处理,对机械高负载滚动接触件进行无流体润滑的解决方案。作为试点应用,选择了系统滚柱轴承线性导轨,因为这在技术上具有高度相关性,并且典型的负载范围(振荡运动、停机时间)注定用于无流体润滑。这是要论证技术可行性的地方,需要形成稳定的转移膜。一方面,这是为了将摩擦系统的基体和配对体分开,以确保低磨损运行并同样减少摩擦,从而也存在热亚临界平衡状态。最初使用简单的摩擦学测试来评估各种固体、表面改性和交付选项。借助现代表面分析,可以分析层形成过程中的底层转移过程并确定有针对性的解决方案。使用以下数值方法(FEA 和分子动力学)对作用机制进行建模。其次,将研究结果转移到真实的演示系统中。该研究项目的主要目标是确定滚动接触中形成转移膜的机制,并能够借助合适的模型从理论上描述它们。因此,可以导出措施来有针对性地控制过程,最终直接在实际系统中进行控制。该项目的创新方法不仅是提供固体润滑剂,而且还通过表面改性对要形成转移膜的表面进行最佳调节。
英文摘要
Within the framework of the project, a solution is to be shown how mechanically high loaded rolling contacts can be lubricated fluid-free through the use of suitable solids and an adapted surface treatment of the counter-body. As a pilot application, a system roller bearing linear guide was selected, since this is technically highly relevant and the typical load spectrum (oscillating motion, downtime) is predestined for a fluid-free lubrication. This is where the technical feasibility is to be demonstrated and it is necessary that a stable transfer film be formed. On one hand, this is intended to separate the base body and the counter body of the tribological system in order to ensure low-wear operation and likewise to reduce the friction, so that a thermally subcritical equilibrium state is also present. Initially various solids, surface modifications and delivery options are evaluated using simple tribological tests. With the aid of modern surface analysis, the underlying transfer processes during layer formation are analyzed and targeted solutions identified. The following numerical methods (FEA and molecular dynamics) are used to model mechanisms of action.Secondly, the findings are transferred to a real demo system. The main goal of this research project is to identify the mechanisms leading to transfer film formation in rolling contacts and to be able to describe them theoretically with the help of suitable models. As a result, measures can be derived to control the processes in a targeted manner, ultimately directly in the real system. The innovative approach of the project is not only to provide a solid lubricant but also to optimally condition the surfaces on which the transfer film is to be formed by means of surface modification.
