自润滑关节轴承寿命的计算和预测对于提高装备的运行安全性具有重大的意义。针对自润滑关节轴承磨损寿命计算和预测的需求,从自润滑关节轴承的磨损机理出发,依据材料摩擦磨损理论,采用组合磨损计算方法分别建立了自润滑推力关节轴承和向心关节轴承的磨损寿命模型。该模型综合考虑了影响自润滑关节轴承寿命的磨损机理、结构特点、工作特性以及零部件功能要求等因素,特别是将结构参数和功能要求显式地在模型中表示,可直接反映结构变化和功能要求对自润滑关节轴承磨损寿命的影响。计算实例和分析结果表明:相对目前使用的自润滑关节轴承经验计算公式,本文模型计算结果准确,理论依据更充分,对于特殊结构和功能的特种自润滑关节轴承适用性更好。

Wear-life forecast of self-lubricating spherical plain bearing has very great significance to the operating security of equipment.To meet the demand of wear-life calculation and forecast of self-lubricating spherical plain bearing,the wear-life models for self-lubricating thrust spherical plain bearing and self-lubricating radial spherical plain bearing were created based on the principle of joint wear calculation method and the wear mechanism of self-lubricating radial spherical plain bearing.The models proposed integrated the wear mechanism of self-lubricating radial spherical plain bearing,the friction wear laws of materials,configuration,mating characteristic of the self-lubricating spherical plain bearing,and function requirement.Especially,the configuration parameters and function requirement were more specific in the models to different types and functions of self-lubricating spherical plain bearing.Example results and analysis on the models showed that the model can calculate the wear life accurately,and it is more theoretical and has a good applicability to the special designed and applied self-lubricating spherical plain bearing compared with the experiential calculation formulas used at present.
