高速深沟球轴承广泛应用于新能源汽车驱动电动机及减速箱中,随着新能源汽车的技术发展,对其精度、寿命和可靠性提出了更高的要求。高速深沟球轴承失效的主要形式之一是保持架断裂。系统分析了高速深沟球轴承中保持架的受力来源及对应状态下的应力及应变状态,发现保持架自身离心力是最大影响因素;有针对性地提出了高速保持架设计方案;采用Abaqus及CABA3D进行仿真验证,并通过了台架试验及客户装机测试。研究对高速深沟球轴承的保持架设计、提高轴承可靠性等具有重要借鉴意义。
High-speed deep groove ball bearings are widely used in drive motors and reducers of new energy vehicles
and the requirements of bearing accuracy
life and reliability are getting higher and higher with development of new energy vehicles technology. One of the main failures of high speed ball bearings is cage fractures. In this study
the relationship between the cage stress and the strain is systematically analyzed
the centrifugal force of the cage itself is indicated as the biggest influencing factor
and key points of cage design are proposed. The simulation results are verified by Abaqus and CABA3D; the bench test and customer installation testing are verified. The research is important for cage design of high speed ball bearings and improving bearing reliability.
