Abstract

Abstract

In order to establish the bearing wear life analysis method of nuclear reactor control rod rotating device and optimize the existing experimental bearing life analysis means of rotating device, by constructing the bearing mechanical analysis model under operating conditions, the contact mechanical characteristics of raceway-roller are obtained. Through the ring control theory, combined with the operating characteristics of the rotating device, the motion characteristics between the bearing roller and the inner and outer raceways are obtained. The wear analysis model of the bearing under the operating condition of the rotating device is constructed based on the Archard wear model, and the wear characteristics between the bearing raceway and the roller are obtained by using the wear iterative method. The research results show that the bearing wear life obtained by the bearing wear life analysis method established in this paper is in good agreement with the test results, and can be used for the bearing wear life analysis of the control rod rotating device in nuclear reactors.
