摘　　要：润滑和磨损特性一直为机械工业所密切关注。通过振动式混合机对镀锌钢球在液体中的振动磨损实验,研究了磨损量和润滑油特性之间的关系。分别选用聚四氟乙烯(PTFE)和不锈钢两种小瓶,选用合成润滑油等四种液体,在不同温度下进行钢球的振动磨损实验,测得相应的磨损量。磨损量采用差重法获得,采用标准砝码调零的称量方法来提高差重法的准确性。从钢球在润滑油中运动的角度结合流体力学理论推导了磨损量与润滑油特性的关系;根据此关系对使用聚四氟乙烯小瓶和不锈钢小瓶得到的实验数据进行了关联,发现使用不同的小瓶时小球在润滑油中的运动规律是一致的。此外,所提出的磨损实验方法可用于润滑油润滑性能的评定。Lubrication and wear characteristics have been closely watched by the machinery industry.In this paper,relationship between attrition amount and lubricating oil characteristics was studied by attrition test of galvanized steel balls in liquid with vibrating mixer.Two kinds of vials made of Teflon(PTFE)and stainless steel were used and four kinds of liquids including synthetic lubricating oil were selected,the attrition test was carried out at different temperatures and then corresponding attrition amount was measured.The amount of attrition was obtained by different method,zeroing with standard weights was implemented to improve the accuracy of the method.From the perspective of movement of steel balls in the lubricating oil,combined with the theory of fluid mechanics,relationship between attrition amount and characteristics of lubricating oil was derived.Based on this relationship,experimental data obtained when using PFTE vials and stainless steel vials were correlated respectively.It was found that the motion of steel balls in lubricating oil was consistent when using different vials.In addition,the attrition test method proposed in this paper could be used to evaluate the lubricating performance of other lubricating oils.
