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f_(c)、陶瓷球特征频率f_(b)的倍频、内圈特征频率f_(i)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。Here,to investigate effects of cage on vibration characteristics of full ceramic ball bearing under cryogenic working condition,theoretical and test studies were conducted for silicon nitride full ceramic ball bearing under cryogenic working condition.Vibration signal characteristics of full ceramic ball bearings equipped with different material cages were tested and analyzed.The study results showed that vibration characteristics of cage are similar to contribution featural frequencies of its stress state with main components of cage feature frequency f_(c),frequency doubling of ceramic ball feature frequency f_(b),frequency doubling of inner ring feature frequency f_(i)and coupling feature frequencies between cage and inner ring;by changing axial load and test temperature,vibration speeds of full ceramic ball bearings equipped with polymer based and bakelite cages are lower than those of full ceramic ball bearings equipped with carbon fiber composite material cages;however,kurtosis values of full ceramic ball bearings equipped with carbon fiber composite material cages are lower than those of full ceramic ball bearings equipped with bakelite and polymer based composite material cages,i.e.,for signal stability and reducing fault probability of full ceramic ball bearings,carbon fiber composite materials are superior to bakelite and polymer based composite materials;the study results have certain reference and lesson values for choosing full ceramic ball bearing cages under cryogenic working condition.
