摘 要: A method for accelerated zero-failure testing was proposed for rolling bearings at high operational temperature. The life-load relationship of rolling bearings is combined with the Arrhenius model based on a life-temperature relationship on bearing lubricants to take the temperature effect on bearing life into consideration. Testing duration was calculated to demonstrate at least 90% reliability at a designed rating life of rolling bearings with a given confidence level under the service load and temperature conditions. A step by step procedure for calculating equivalent bearing load and speed was also proposed using a data of load distribution duration of bearings. Finally, an example was given for the case of a deep-groove ball bearing.

针对高运行温度下的滚动轴承,提出了一种加速零故障测试方法。将滚动轴承的寿命-载荷关系与基于轴承润滑剂的寿命-温度关系的阿伦尼乌斯模型相结合,以考虑温度对轴承寿命的影响。通过计算测试持续时间,证明在给定的置信水平下,在设计的滚动轴承额定寿命和给定的运行载荷及温度条件下,至少能保证 90%的可靠性。还提出了使用轴承载荷分布持续时间数据来计算等效轴承载荷和转速的逐步计算步骤。最后,给出了一个深沟球轴承的实例。
