密封球轴承摩擦力矩计算模型

Calculation Model of Friction Moments in Sealed Ball Bearings

从量纲分析着手,对密封球轴承摩擦特性的主要影响因素——负荷、转速、装脂量和密封唇过盈量进行了大量的试验分析,着重探讨了装脂量、密封件对密封球轴承摩擦力矩的影响,得出了回归分析模型。给出了适合接触式,非接触式密封球轴承以及开式轴承的摩擦力矩计算模型,为密封球轴承摩擦力矩的估算提供了经验公式,并为密封球轴承CAD建立分析软件提供了依据,附图1幅,表5个,参考文献6篇。

The main factors, that is, load, speed, packed grease amount and interference amount of seal lips, which influence the friction characters of sealed ball bearings, are experimentally analyzed a lot by means of dimension analysis.The regression analysis m'odel is obtined throngh emphatically researching the influence of packed grease amount and seal elements on the friction moment of sealed ball bearings. The calculation model of friction moments suitable for contact and non-contact sealed ball bearings and opentype bearings is given. The model provides the empirical formula for evaluating the friction moments of sealed ball bearings and provides the basis for sealed ball bearing CAD.
