摘要
轴承的抗断油能力直接影响航空发动机的可靠性。为了探究一种新型无保持架角接触球轴承的干运转性能,设计了轴承环下断油试验方案,构建了断油试验平台及运行程序,分析了断油之后的轴承外观形貌、温度、转速及电流等变化情况。试验结果表明,在高转速、高轴向载荷工况下,新型轴承的干运转时间为51 min,验证了该新型轴承具有良好的抗断油能力,可以在机械工业领域广泛应用。
The ability of bearings to resist oil interruption directly affects the reliability of aero engines.In order to explore the dry operation performance of a novel cageless angular contact ball bearing,an oil break test scheme under the bearing ring is designed,and a test platform and an operation program are constructed.The changes of bearing appearance,temperature,speed and current after oil cut off are analyzed.The results show that the dry running time of the new type of bearings is 51 min under high rotation speed and high axial load.It proves that the new type of bearings has good anti-oil interruption ability,and can be widely used in industry.
