气油润滑由于其供油量正、控制精确，已广泛应用于高速主轴轴承。在这项研究中，空气-油润滑条件的影响，如排油量，排油间隔，油粘度，空气供应率和管长度，相对于供油率的变化进行了分析。利用由油气润滑单元、吸油纸进给单元和图像处理单元组成的油气润滑特性评价系统进行了分析。从油气润滑单元排出的供油量的变化作为由图像处理单元测量的吸油纸上的油带宽的变化率来测量。建立了基于响应面法的油膜带宽变化率预测模型，并通过在各种油气润滑工况下预测的油膜带宽变化率与实测值的比较，验证了模型的可靠性。特别地，通过分析实验因素之间的相互作用，研究了油带宽的变化与空气-油润滑条件之间的关系。
Air-oil lubrication has been widely used for high-speed spindle bearings because its oil delivery is positive and can be controlled very accurately. In this study, the effects of air-oil lubrication conditions, such as the oil discharge quantity, oil discharge interval, oil viscosity, air supply rate and tube length, were analyzed with respect to the variation of the oil supply rate. The analysis was carried out by using an air-oil lubrication characteristics evaluation system which was consisted of an air-oil lubrication unit, oil absorbent paper feeding unit and image processing unit. The variation of the oil supply rate discharged from the air-oil lubrication unit was gauged as the variation ratio of the oil band width on the oil absorbent paper measured by the image processing unit. A prediction model for the variation ratio of the oil band width was established based on a response surface method, and its reliability was proved by the fact that the predicted variation ratios of the oil band width agreed well with the measured variation ratios under the various air-oil lubrication conditions. In particular, the relationships between the variation of the oil band width and the air-oil lubrication conditions were examined by analyzing the interactions between the experimental factors.
