摘要/Abstract

摘要： 基于齿轮耐久性能试验台开展了一系列干接触/油润滑下POM(聚甲醛)-POM齿轮副承载能力试验，并测量了服役过程中的轮齿温度、磨损量、齿廓精度和齿面形貌。试验发现，POM齿轮失效形式与载荷和润滑方式有关。通过对齿面微观形貌和磨屑表征，确认干接触下POM齿轮主要磨损模式为黏着磨损与磨粒磨损，而油润滑下POM齿轮失效形式为接触疲劳失效。由于润滑油减少了齿面摩擦，降低了运行温度，延缓了齿面劣化程度，因此POM齿轮在油润滑下的承载能力明显提高。

Abstract: A series experimental work on the load capacity of POM-POM gear pairs was conducted based upon a gear durability test rig, together with the measuring examination of tooth temperature, wear volume, tooth profile deviation and surface morphology. Several loading levels were chosen under both of the dry contact and the lubrication conditions. Experimental results reveal that the failure modes of POM gears are related to the loading levels and lubrication modes. The wear modes of POM gears are identified as adhesive wear and abrasive wear through the characteristic analysis of tooth flank microtopography and debris. Meanwhile, the failure mode of POM gears under oil lubrication is contact fatigue failure. As the oil reduces the tooth surface friction and running temperature, the tooth surface deterioration is delayed and the load capacity of POM gears increases.

Key words: polyoxymethylene(POM) gear, lubrication method, tooth temperature, wear mode, failure mode
