摘要

In order to rank bearing materials, lubricants and design variables using rolling-element bench type fatigue testing and rolling-element bearing tests, the investigator needs to be cognizant of the variables that effect rolling-element fatigue life and be able to maintain and control them within an acceptable experimental tolerance. Once these variables are controlled, the number of tests and the test conditions need to be specified to assure reasonable statistical certainty of the final results. Using the statistical methods of W. Weibull and L. Johnson, the minimum number of tests required can be determined. There is a reasonable correlation between the results from elemental test rigs with those results obtained with full-scale bearings. This paper brings together and discusses the technical aspects of rolling-element fatigue testing as well as making recommendations to assure quality and reliable testing of rolling-element specimens and full-scale rolling-element bearings.
