作者根据高温真空下自润滑保持架转移润滑的特点,论述了几种轴承结构类型及其主要参数设计时应考虑的因素和确定方法。从实践中作者认为,该类轴承采用单列向心推力球轴承或三点接触球轴承为宜。其游隙除工作游隙外,尚需考虑转移膜及其滞留松散磨屑所需之游隙。沟曲率应取较大值,保持架采用球引导方式为宜 According to the characteristics of transfer lubrication of self-lubricating cage under high temperature and vacuum conditions, the author discusses the factors that should be considered in the design of several kinds of bearing structures and their main parameters and the determination methods. In practice, the authors believe that this type of bearing using single row radial ball bearings or three-point contact ball bearings is appropriate. In addition to the clearance of its clearance, but also need to consider the transfer film and its retention loose debris required clearance. Groove curvature should take a larger value, the cage ball guide method is appropriate
