摘要

为探究保持架对低温工况下全陶瓷球轴承振动特性的影响，开展氮化硅全陶瓷球轴承低温工况下的理论与试验研究，测试并分析装配有不同材料保持架的全陶瓷球轴承振动信号特征。研究结果表明，保持架的振动特性与其受力状态的贡献特征频率类似，均以保持架特征频率fc、陶瓷球特征频率fb的倍频、内圈特征频率fi的倍频及保持架与内圈耦合的特征频率成分为主；改变轴向载荷及试验温度，装有聚合物基和胶木保持架的全陶瓷球轴承振动速度小于装有碳纤维复合材料保持架的全陶瓷球轴承，但装有碳纤维复合材料保持架的全陶瓷球轴承峭度值小于装有胶木和聚合物基复合材料保持架的全陶瓷球轴承，即在全陶瓷球轴承信号平稳性以及降低故障概率方面，碳纤维复合材料要优于胶木和聚合物基复合材料。研究结果对于低温工况下全陶瓷球轴承保持架的选取具有一定的参考与借鉴价值。

Abstract

To investigate the effect of cage on vibration characteristics of full ceramic ball bearings under cryogenic condition, theoretical and experimental research is carried out for silicon nitride full ceramic ball bearings under cryogenic condition, and vibration signal characteristics of full ceramic ball bearings equipped with cages of different materials are tested and analyzed. The results show that the vibration characteristics of the cage is similar to the contribution characteristic frequency of its stress state, which are mainly composed of the characteristic frequency of cage fc, the frequency doubling of ceramic ball characteristic frequency fb, the frequency doubling of inner ring characteristic frequency fi and the characteristic frequency components of cage and inner ring coupling. The vibration velocity of full ceramic ball bearings equipped with polymer matrix composite and bakelite cage is lower than that of full ceramic ball bearing equipped with carbon fiber composite cage, while the kurtosis value of the full ceramic ball bearing equipped with carbon fiber composite cage is lower than that of the full ceramic ball bearings equipped with bakelite and polymer matrix composite cages. In other words, carbon fiber composite is superior to bakelite and polymer matrix composite in signal stability and fault probability reduction of full ceramic ball bearing. The research results have a certain reference value for the selection of full ceramic ball bearing cage under cryogenic condition.
