良好的润滑条件是降低机械运动副金属元件表面摩擦和减少磨损的最有效方法之一。针对差速器总成中行星齿轮轴的摩擦磨损失效过快问题,研究富勒烯C60纳米碳球润滑油对行星齿轮轴的抗磨减摩作用。
方法
2
开展富勒烯C60润滑油作用下的摩擦磨损实验,分析C60纳米碳球浓度对摩擦因数和磨痕表面形貌的影响;使用变速器总成疲劳寿命试验台,开展差速器行星齿轮轴疲劳磨损试验,观测C60纳米碳球对齿轮轴的减摩效果。
结果

分析表明,富勒烯C60纳米碳球润滑油作用下的平均摩擦因数最低为0.080 1,比基础润滑油降低了71.1%;行星轮轴销两端磨损量均降低约60%。
Objective
2
Effective lubrication is one of the most efficient methods for reducing friction and minimizing wear on metal component surfaces in mechanical motion pairs. To address the rapid friction and wear failure of the planetary gear shaft in differential assemblies
this study investigates the anti-wear and friction-reduction effects of fullerene C60 nano-carbon sphere lubricant on planetary gear shafts.
Methods
2
Friction and wear experiment were conducted under the action of fullerene C60 lubricant to analyze the influence of C60 nano-carbon sphere concentration on the friction coefficient and wear scar surface morphology. Additionally
a transmission assembly fatigue life test bench was utilized to perform fatigue wear experiments on the differential planetary gear shaft
observing the friction-reducing effects of C60 nano-carbon spheres on the gear shaft.
Results
2
The analysis results demonstrated that the average friction coefficient under the action of fullerene C60 nano-carbon sphere lubricant was as low as 0.080 1
representing a 71.1% reduction compared to the base lubricant. Furthermore
the wear on both ends of the planetary gear shaft pins decreased by approximately 60%.
