Abstract

Polytetrafluoroethylene (PTFE) is widely utilized in engineering applications due to its low friction, self-lubricating properties and chemical inertness. However, its tribological performance under variable loading conditions has been insufficiently studied. This research investigates the influence of variable loading on the wear and friction characteristics of PTFE under dry sliding conditions, particularly within the context of rolling and sliding contact bearings. A modified pin-on-disk tribometer equipped with a variable loading assembly was used to simulate fluctuating load scenarios commonly encountered in bearing applications. The results show that PTFE experiences wear rates that fall between those observed under mean and maximum constant loading conditions, with a notable increase in wear and specific wear rate compared to mean static loads. However, no similar trend was observed for the friction coefficient. These results provide insightful information on the optimization of PTFE performance in dynamic environments including bearings, biomedical implants, and mechanical seals.

干滑动动载荷作用下未填充PTFE的摩擦学行为
聚四氟乙烯(PTFE)由于具有低摩擦、自润滑和化学惰性等特性,在工程应用中得到了广泛的应用。然而,其在变载荷条件下的摩擦学性能研究还不够充分。本研究探讨了干滑动条件下变载荷对PTFE磨损和摩擦特性的影响,特别是在滚动和滑动接触轴承的情况下。采用一种改进的带可变载荷组件的销盘摩擦计来模拟轴承应用中常见的波动载荷情况。结果表明,PTFE的磨损率介于平均和最大恒定载荷条件下的磨损率之间,与平均静态载荷相比,磨损率和比磨损率显著增加。然而,摩擦系数没有观察到类似的趋势。这些结果为动态环境中PTFE性能的优化提供了有见地的信息,包括轴承,生物医学植入物和机械密封。
