Abstract

Little has been published on the behaviour of polymer gears operating under lubricated conditions. An experimental and analytical programme was undertaken to classify the regimes of EHL under which polymer spur gears operate. In doing so theoretical film thicknesses were calculated and then used to classify the regime according to Johnson's Map. The effects of lubrication on the operating efficiencies of high-performance polymer gears were interpreted and from these results coefficients of friction were derived. In addition to this the effect of tooth geometry was investigated and the beneficial influence of high-pressure angle tooth geometry is demonstrated. At loads typically associated with polymer gears the operating regime is shown to be mixed film lubrication. When high-pressure angle gears were tested at high loads the operating regime became full film lubrication and relatively little tooth flank damage occurred.
高性能聚合物直齿齿轮的润滑机制
很少有发表的行为的聚合物齿轮在润滑条件下运行。进行了一项实验和分析程序,对聚合物直齿齿轮运行的EHL制度进行了分类。在这样做的过程中,理论薄膜厚度被计算出来,然后用来根据约翰逊的地图对体系进行分类。分析了润滑对高性能聚合物齿轮工作效率的影响,并推导了摩擦系数。此外,还研究了齿形的影响,证明了高压角齿形的有利影响。在负载通常与聚合物齿轮相关的操作制度显示为混合膜润滑。当高压角齿轮在高负荷下测试时,工作状态变为全膜润滑,齿侧损伤相对较小。
