Biodegradable Lubricating Oil Synthesis Oil Gear Scoring Fatty Acid Ester Two-Roller Test Power-Circulating Gear Machine

项目摘要

To clarify the scoring resistance of biodegradable synthesis lubricating oil made of fatty acid ester, a gear test was carried out using a power- circulating gear machine and a two-roller test was carried out using an Amsler machine. Further, the scoring resistance of the synthesis ester oil was compared with that of vegetable oils. From the test, following results were obtained.(1)In the two-roller test, the seizure resistance of the synthesis ester oil without additives was about 1.5 times as large as that of turbine oil without additives.(2)In the two-roller test, the coefficient of friction of the turbine oil without additives was between 0.06 and 0.08. On the other hand, the coefficient of friction of the synthesis ester oil was between 0.04 and 0.07.(3)In the gear test, the scoring resistance of the synthesis ester oil without additives was about 2.3 times as large as that of the turbine oil without additives.(4)In the gear test, the critical surface temperature for scoring of the synthesis ester oil was approximately 200℃ higher than that of the turbine oil without additives, and it was about 400〜440℃.(5)In the gear test, the sound pressure level, the acceleration due to vibration of gear box and loss torqe in case of the synthesis ester oil without additives were lower than those of the synthesis ester oil with additives.(6)The effects of oxidation inhibitor and anti-wear additive on the scoring resistance and the seizure resistance of the synthesis ester oil were not recognized.(7)The scoring resistance of rapeseed oil without additives was about 1.7 times as large as that of the turbine oil without additives. On the other hand, the scoring resistance of the synthesis ester oil without additives was about 2.3 times as large as that of the turbine oil without additives.

为了阐明由脂肪酸酯制成的可生物降解的合成润滑油的耐擦伤性，使用动力循环齿轮机进行齿轮试验，并使用Amsler机进行双辊试验。此外，将合成酯油的耐划伤性与植物油的耐划伤性进行比较。从试验中，获得了以下结果。(1)In在双辊试验中，不含添加剂的合成酯油的抗咬合性是不含添加剂的涡轮机油的抗咬合性的约1.5倍。(2)In在双辊试验中，不含添加剂的涡轮机油的摩擦系数在0.06和0.08之间。另一方面，合成酯油的摩擦系数在0.04和0.07之间。(3)In在齿轮试验中，不含添加剂的合成酯油的抗划伤性是不含添加剂的涡轮机油的抗划伤性的约2.3倍。(4)In在齿轮试验中，合成酯油的划伤临界表面温度比不加添加剂的涡轮机油高约200℃，约为400 ~ 440℃。(5)In不加添加剂的合成酯油的齿轮试验、声压级、齿轮箱振动加速度和损失转矩均低于加添加剂的合成酯油。（6）抗氧剂和抗磨剂对合成酯油的抗划伤性和抗咬合性影响不大。（7）不加添加剂的菜籽油的抗划伤性是不加添加剂的涡轮机油的1.7倍。另一方面，不含添加剂的合成酯油的耐划伤性是不含添加剂的涡轮机油的耐划伤性的约2.3倍。
