摘　　要：通过射流形态拍摄、液滴分布和尺寸测量及油气润滑供油量台架试验对新型导流式油气润滑喷嘴进行了优越性研究,分析了喷嘴导流体结构参数对轴承润滑效果的影响。最后将有AF涂层和未作任何处理的导流体对轴承润滑效果的影响进行对比可知,导流体材料表面能并非越小越好。The superiority of new guide type nozzle in oil-air lubrication is studied through jet flow form shooting,droplet distribution,size measurement and bench test for oil supply amount in oil-air lubrication. The influences of structural parameters for guiding fibers of nozzle on lubrication effect of the bearings are analyzed. Finally,the influences of guiding fibers coated with and without AF coating on lubrication effect of the bearings are compared. The result shows that the surface energy for materials of guiding fibers is not the smaller the better.
