- Abstract
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.
