A Study on Scoring Resistance of Gears of Biodegradable Synthesis Lubricating Oil

为明确脂肪酸酯类生物降解合成润滑油的抗划破性，在动力循环齿轮机上进行了齿轮试验，在阿姆斯勒齿轮机上进行了双辊试验。并将合成的酯油与植物油的抗刻蚀性进行了比较。试验结果如下：(1)在双辊试验中，不含添加剂的合成酯油的抗癫痫性是不含添加剂的汽轮油的1.5倍左右。(2)在双辊试验中，未添加添加剂的汽轮油的摩擦系数在0.06 ~ 0.08之间。合成酯油的摩擦系数在0.04 ~ 0.07之间。(3)在齿轮试验中，无添加剂合成酯油的抗划痕性约为无添加剂涡轮油的2.3倍。(4)在齿轮试验中，合成酯油的临界表面温度比未添加添加剂的汽轮油高约200℃，约为400 ~ 440℃。(5)在齿轮试验中，无添加剂合成酯油的声压级、齿轮箱振动加速度和损失力矩均低于有添加剂合成酯油。(6)抗氧化剂和抗磨添加剂对合成酯油抗划伤性和抗癫痫性的影响未被认识。(7)不添加添加剂的菜籽油的抗划痕性是不添加添加剂的汽轮油的1.7倍左右。另一方面，未添加添加剂的合成酯油的抗划痕性约为未添加添加剂的涡轮油的2.3倍。

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.
