项目摘要

The scoring-load capacities of the vegetable oils with anti-wear additive of Phosphoric Acid-Dibutyl (DBPo) were studied by using a power-circulating gear test rig. The tests were carried out under a slash-pan lubrication. From the tests, the following results were obtained. (1) The scoring-load capacities of the vegetable oils increased in following order : Turbine oil<Corn oil<Soybean oil<Rapeseed oil. The normal load per unit face width, Pn, at the incipient stage of scoring when lubricated with the rapeseed oil was approximately 1.7 times as large as that when lubricated with a turbine oil. (2) With respect to the vegetable oils with DBPo additive, surface failure by scoring didn't occur at the final load range in tests. The increases in the scoring-load capacities of rapeseed oil, corn oil and soybean oil with DBPo additive were over 78N/mm, over 378N/mm and over 449N/rnm, respectively. (3) The critical temperature at a risk for scoring with the rapeseed oil was about 400℃, and was the highest of all test oils. On contrast, the critical temperature with the vegetable oils with DBPo additive exceeded about 400℃.

利用动力循环齿轮试验机研究了添加二丁基磷酸（DBPo）抗磨剂的植物油的抗划伤能力。试验是在斜盘式润滑条件下进行的。从试验中获得了以下结果。(1)植物油的减载能力依次为：涡轮机油<玉米油<大豆油<菜籽油。当用菜籽油润滑时，划痕初期阶段每单位面宽的法向载荷Pn约为用涡轮机油润滑时的1.7倍。(2)添加DBPo的植物油在试验的最后载荷范围内没有发生表面划痕破坏。添加DBPo后菜籽油、玉米油和大豆油的抗氧化能力分别提高了78 N/mm以上、378 N/mm以上和449 N/mm以上。(3)菜籽油产生划痕的临界温度约为400℃，是所有试验油中最高的。而添加DBPo的植物油的临界温度超过400℃。
