摘　　要：陀螺仪高速转子球轴承是陀螺仪的核心元件，其精度、寿命及可靠性对陀螺仪的性能、寿命及可靠性影响极大。对失效轴承的分析表明．润滑是陀螺仪球轴承使用寿命及可靠性的核心问题。轴承优化设计时应将润滑系统综合考虑．同时还要考虑润滑载体─-保持架及摩擦表面的物理性能及表面状态等。Gyro high - speed rotor ball bearing is a key element of gyroscope, influence of its accuracy,life and reliability on gyroscope's performance, life and reliability is extremely great. Analyzing failed bearings showed: lubrication is the key problem of service life and reliability of gyro ball bearings. In optimization of design for bearings, lubricating system should be considered comprehensively, in the mean time physical performance and surface condition of lubrication carrier - cage and rubbing surface are also considered.
