本文回顾了在过去十年左右的陶瓷滚动体轴承领域的一些广泛的研究。作为这项工作的结果，热等静压氮化硅（HIPed Si 3 N4），已成为一个非常有前途的材料，用于制造高性能的全陶瓷或混合钢/陶瓷滚动接触轴承。与传统的钢轴承相比，氮化硅轴承在滚动接触疲劳寿命方面具有显著的优势，并且材料的低密度大大降低了在机床主轴和燃气涡轮机发动机等极高速应用中球/滚道接触处的动态载荷。研究表明，在极端温度、大温差、高速、超高真空等苛刻润滑和磨损条件下以及在安全关键应用中使用氮化硅轴承具有特殊优势，例如，它们可以满足飞机发动机短时间断油运行的要求。其他已被证明的好处是耐腐蚀性和受污染的润滑剂的耐受性。由于其持续的发展和测试，预计氮化硅轴承将继续在所有类型的应用中获得广泛的认可。
The paper reviews some of the extensive research in the field of ceramic rolling element bearings that has been carried out over the past decade or so. As a result of this work hot isostatically pressed silicon nitride (HIPed Si3N4), has emerged as an extremely promising material for fabricating high performance all-ceramic or hybrid steel/ceramic rolling contact bearings. Compared with conventional steel bearings silicon nitride bearings have been shown to offer significant benefits in terms of rolling contact fatigue life, and the lower density of the material greatly reduces the dynamic loading at ball/raceway contacts in very high speed applications such as machine tool spindles and gas turbine engines. Investigations have shown the particular benefits of using silicon nitride bearings in severe lubrication and wear conditions such as extreme temperature, large temperature differential, high speed, ultra-high vacuum and in safety-critical applications where, for example, they can respond to the requirements of short periods of oil-off operation in an aircraft engine. Other benefits which have been demonstrated are corrosion resistance and tolerance of contaminated lubricants. As a result of their sustained development and testing it is expected that silicon nitride bearings will continue to achieve wide acceptance in all types of applications.
