摘要
滚动轴承在非稳定载荷作用下,逐步受损,承载能力也逐渐下降。根据疲劳损伤累积理论,对这一过程进行了讨论,使定量确定受损伤滚动轴承的剩余寿命和许用当量动负荷,较为方便和简洁。
Rolling-bearings suffered from varying-amplitude cycle loads are damaged along with the process of loading. In this paper, bearings damaged by fatigue are studied, with the purpose of appraising the load-life behavior of them. A new method of fatigue design for bearings is recommended and an example is provided. Results of examples show that the new method is simple and reliable.
