【摘要】 采用离心分油试验机和滚筒试验机在不同温度下对润滑脂进行剪切和动态分油性能试验。采用振动仪测定不同状态的润滑脂对轴承振动的影响 ,对试验结果的分析表明 :润滑脂进入接触区的难易程度是影响振动性能的主要因素 ,良好的动态分油能力和适度的皂纤维尺寸可缓解轴承中的贫油状态更多还原

【Abstract】 The shearing test and dynamic separating oil property test for the grease in different temperatures have been made by centrifugal separating oil tester and roller tester. The effect of grease in different states on bearing vibration are measured by vibration instrument .The results show that difficult or easy degree which lubrication oil enters contact areas is main factor affecting bearing vibration, and favorable dynamic separating oil ability and proper soap fiber length can improve poor oil status in the bearing.更多还原
