摘要
在干摩擦、水润滑条件下,考察了PA1010、PTFE、胶木4012与45#钢滚动接触时的摩擦行为以及三种聚合物的静态蠕变特性.研究结果表明,两种实验环境下三种偶副的滚动摩擦系数均随转速增加呈上升趋势;同样转动速度下,钢/PA1010的滚动摩擦系数最大,其次为钢/PT-FE,而钢/胶木配副时滚动摩擦系数最小.理论分析显示这一现象与三种聚合物材料的粘弹性密切相关.
The creep characteristics and the rolling friction behavior of three polymers (PA1010, PTFE bakelite 4012), and 45 steel were studied in this paper. The results indicated that the rolling friction coefficients of three polymers increased with the rotational speed increasing both in dry friction and water lubricating conditions. The tribopair with maximum rolling friction coefficient was steel/PA1010, followed by steel/PTFE, while steel/bakelite had the minimum rolling friction coefficient. Theoretical analysis indicates the phenomenon is closely connected with the viscoelasticity of these three polymers.
