减摩剂、油性剂在RV90型减速机专用蜗轮蜗杆润滑油中的应用研究

以320#聚醚类合成油为基础油,选择如下减摩剂、油性剂：含磷化合物类摩擦改进剂、二聚酸、油酸乙二醇酯、硬脂酸丁酯、硫化烯烃棉籽油、二烷基二硫代磷酸氧钼等润滑剂,在工艺和技术条件都相同的情况下,制备了几种RV90型减速机专用蜗轮蜗杆润滑油试验油样。文章采用四球机试验和RV90型减速机台架评定试验作为主要测试手段,通过检测试验油样的减摩抗磨性能来间接判定减摩剂、油性剂的优劣。减摩抗磨性能检测表明上述润滑剂可以有效提高RV90型减速机专用蜗轮蜗杆润滑油的摩擦学性能,其中含磷化合物类摩擦改进剂、二聚酸与硬脂酸丁酯复配使用的效果最佳。

Application Research on Friction -Reducing Agent and Oiliness Agents in Special Worm Gear Lubricant for RVg0 Reducer

Taking 320＂ synthetic oil as base oil and phosphorus -containing friction modifier, dimer acid, ethylene glycol ole- ate, butyl stearate, sulfurized olefin cotton oil and sulphurized oxymolybdenum dithiophosphate, etc. as friction -reducing agent and oiliness agents, several oil samples for RVg0 special worm gear lubricant were prepared under the same process and technical condition. In this article, four- ball test and RVg0 reducer bench evaluation test were used as the main test methods to judge the quality of friction - reducing agent and oiliness agents by testing the friction - reducing and antiwear properties of oil samples. The test showed that the above additives can effectively improve the tribological properties of Rv90 special worm gear lubricant, among them, the combination of phosphorus - containing friction modifier, dimer acid and butyl stearate has better synergistic effect.
