Abstract

Abstract

The lubricating grease degradation and aging performance is critical to the reliability of spacecraft deployment mechanisms, moving components, and other related products. Limited research has been conducted on the effects of grease aging on performance and lifespan prediction, with insufficient theoretical support for the application of long-life lubricating grease in spacecraft. The quality change rate was selected as the key performance for aging failure, a time temperature equivalent model based on the quality retention rate of lubricating grease was obtained by means of the Arrhenius equation and the time temperature relationship, which can predict the quality change of lubricating grease under various storage conditions. Key parameters such as the droplet point and the cone penetration were monitored to evaluate the lubricating grease aging performance. The results show that, aging has a significant impact on the droplet point and the cone penetration performance, with a 1% loss rate of the lubricating grease mass indicating a predicted lifespan of 5.4 a at the failure point. In addition, a 4-ball friction test was used to study the lubricating grease friction performance on bearing steel GCr15 under different loads. The test indicate that aging significantly influences the lubricating grease friction coefficient and the wear zone diameter under high loads. The research results and methods provide a basis for understanding the lubricating grease degradation and aging performance, and predicting its lifespan.
