摘要
直升机减速器润滑系统出现故障,齿轮轴承将处于无润滑油工作状态,使减速器在短时间内破坏,造成灾难性的后果。将2%的T307、T321、T202、T391添加剂分别加入到926和DOD-L-85734航空油中做12Cr2Ni4A钢摩擦副45 min油雾润滑试验。结果表明:抗磨效果最好的是2%T202加入到926航空油和2%T391加入到DOD-L-85734航空油,2%T391加入DOD-L-85734油雾润滑45 min的磨损体积仅是干摩擦43 s磨损体积的1/24。
If the lubrication system of helicopter reducer is destroyed, gears and bearings will be at non-lubricating oil work state, which causes the reducer to be damaged in a very short time and creates disastrous consequence. The various 2% ad- ditives of T307 ,T321 ,T202 ,T391 were mixed with 926 and DOD-L-85734 aeronautical oils to make 12Cr2Ni4A steel pairs 45 min oil-mist lubrication experiments. The results show that the best effect of resistance wear is 926 aeronautical oil contai- ning 2% T202 and DOD-L-85734 aeronautical oil containing 2% T391. The attrition volume of DOD-L-85734 aeronautical oil containing 2% T391 under oil-mist lubrication for 45 min is only 1/24 of the attrition volume of dry friction for 43 s.
