电机中最常使用的滚动轴承,在其实际成绩已超过其理论值的发展过程中,由于采用了从大气溶解材料过渡到真空脱气材料的方法,从而使得轴承寿命得到了延长。另外,还认识到润滑状态对轴承寿命的极大影响,从而更加重视了轴承的诊断以及为保持良好润滑状态的 Rolling bearings, the most commonly used in the motor, have extended their bearing life due to the transition from atmospheric-to-vacuum material to vacuum degassing material as their actual performance has exceeded their theoretical value. In addition, it is also recognized that the lubrication state has a great influence on the bearing life, so as to pay more attention to the bearing diagnosis and to maintain a good lubrication state
