【摘要】 国内外对橡胶材料在煤粉条件下的摩擦磨损特性尚缺乏研究 ,因而对丁腈橡胶在湿煤粉条件下的磨料磨损进行了研究 ,发现其磨损机理为疲劳磨损 ,磨损率随着法向载荷的增大而增大 ,随着旋转速度的增大而减小 ;而摩擦系数则与法向载荷和旋转速度大致无关 ,其中水份在丁腈橡胶磨料磨损中主要起着三个作用 :(1)对煤粉的粘结作用 ;(2 )水膜的润滑作用 ;(3)降低橡胶的工作温度。更多还原

【Abstract】 As the friction and wear of rubber under coal is short of study so far, the three body wear test of NBR under wet coal has been finished, and it has been found that the wear mechanism of NBR under wet coal is fatigue wear The wear rate is increased with the normal load increased, and decreased with the revolving speed increased, in the meantime, the frictional coefficient is nothing with the normal load and revolving speed Three main actions of water on the abrasion includes :(1)adhesion of coal;(2)lubrication of water;(3)reduction of work temperature更多还原
