摘要:
油膜刚度影响静压推力轴承振动幅值和承载能力,严重时将导致静压推力轴承摩擦副接触失效,影响立式数控装备的加工精度和运行稳定性。为了避免此现象发生,本文根据润滑理论和摩擦学原理对恒流环形腔多油垫静压推力轴承油膜刚度进行研究,分析润滑油粘度、工作台旋转速度和承载重量等因素对油膜刚度的影响规律,并进行了实验验证。结果表明:润滑油粘度对油膜刚度有一定的影响,考虑粘度变化时油膜刚度大,计算结果相对精确。空载和承载工况条件下,随着旋转工作台转速增加,间隙油膜变薄,油膜刚度变大。相同旋转速度条件下,承载时油膜厚度小于空载时油膜厚度,承载时油膜刚度大于空载时油膜刚度。理论计算结果与实验值吻合较好,所得结论可为静压推力轴承油膜厚度控制系统设计提供理论依据,提高立式数控加工装备运行稳定性。
