摘　　要：为了研究不同基础油对平面二次包络环面蜗杆传动的影响,进行了跑合试验。试验发现,相对于聚α-烯烃合成油,采用聚乙二醇合成油时,其传动效率会提高4.5%左右,温升降低15℃;采用矿物油时,其传动效率则会降低10%左右,温升提高58℃以上。长期连续工作的平面二次包络环面蜗杆减速器采用聚乙二醇合成油性能更佳;矿物油仅适用于非连续工作且负载较低的场合。当采取散热措施后,可以使用聚α-烯烃合成油。进一步研究发现,最小油膜厚度不足以完全反映采用不同基础油在传动效率和温升方面产生的差异,但是可以用来评价润滑状态。In order to study the influence of different base oils on the lubrication of planar double envelop⁃ing hourglass worm drive,running in test is carried out.It is found that,when using polyethylene glycol synthetic oil,the transmission efficiency increases by 4.5%and the temperature rise is 15℃lower than that of poly-al⁃pha-olefins synthetic oil.When mineral oil is used,the transmission efficiency will be reduced by about 10%,and the temperature rise will increase by more than 58℃.Polyethylene glycol synthetic oil has the better perfor⁃mance for long-term continuous working plane double enveloping hourglass worm reducer.Mineral oil is only suitable for discontinuous operation and low load applications.When heat dissipation measures are taken,poly alpha-olefins synthetic oil can be used.Further research shows that the minimum film thickness is not enough to fully reflect the difference of transmission efficiency and temperature rise caused by different base oils,but it can be used to evaluate the lubrication state.
