摘要

通过测试水润滑橡胶轴承的摩擦力矩，定量分析平面型水润滑橡胶轴承摩擦特性与主轴转速、轴承比压以及回旋振动载荷之间的关系，并建立相应的摩擦系数模型，为准确预测系统在轴承摩擦激励下的振动响应特性提供重要支撑。结果表明，橡胶轴承摩擦系数随着主轴转速升高而减小；相对于磨合初期，充分磨合后的橡胶轴承摩擦系数对主轴转速变化更加敏感；相对于磨合初期，轴承比压对充分磨合后橡胶轴承摩擦特性的影响较小；回旋振动载荷对橡胶轴承摩擦系数的影响主要体现在主轴中速段。

Abstract

The quantitative dependence of friction property of planar-type water-lubricated rubber bearing on spindle speed, bearing pressure and load resulted by whirling vibration was investigated based on friction torque measurement and which was presented mathematically providing an important guarantee for prediction of dynamic response in system excited by bearing friction. Experiment results show that friction coefficient of water-lubricated rubber bearing decreases as spindle speed increases; the friction characteristic under fully run state plays more sensitive to variation of spindle speed than it being in the initial phase; bearing pressure has little influence on friction coefficient if it has been smoothed; the effect of load resulted by whirling vibration mainly plays a part in friction coefficient when the rotor speed is located at intermediate level.
