摘 要: Timken engineers recently worked with defence aircraft builders to develop hybrid roller bearings for several applications, including an aircraft turbine engine offering significantly more power and efficiency than existing low-bypass turbofans. Timken tribology specialists played an important role in R&D, testing the strength of ceramic rollers against a variety of steel grades typically used to make roller-adjacent bearing components. Melissa Kerney, aerospace programme manager, says that the silicon nitride used is the highest available grade and processed to very high standards: "Differentiation to achieve an aerospace-grade product occurs in two stages, both of them in manufacturing."

蒂姆肯工程师近期与国防飞机制造商合作,开发了适用于多种场景的混合式滚子轴承,其中包括一种航空涡轮发动机,其功率和效率远超现有低旁通涡扇发动机。蒂姆肯摩擦学专家在研发过程中发挥了重要作用,对陶瓷滚子的强度进行了测试,对比了用于制造滚子接触轴承部件的各种钢材等级。航空航天项目主管梅丽莎·克尼表示,所使用的氮化硅是目前最高级别的材料,并按照极高的标准进行加工:“实现航空航天级产品的差异化需经过两个阶段,且这两个阶段均在制造过程中完成。”
