【摘要】：由于芳綸材料的苯基團(tuán)極難溶于大多數(shù)化學(xué)物質(zhì),由聚四氟乙烯(PTFE)纖維和芳綸纖維復(fù)合編織而成的自潤滑襯墊與黏接劑的黏接性能較差,從而影響軸承的整體性能。對關(guān)節(jié)軸承自潤滑襯墊進(jìn)行甘油醚接枝改性處理,利用摩擦學(xué)動態(tài)性能試驗(yàn)機(jī)測定襯墊改性處理后的軸承的摩擦學(xué)性能,并分析襯墊改性處理影響軸承摩擦學(xué)性能的機(jī)制。結(jié)果表明:襯墊經(jīng)改性處理后軸承的磨損量、摩擦因數(shù)和摩擦溫升均明顯降低;經(jīng)接枝改性處理后,襯墊的成膜性能得到明顯改善,且隨著擺動頻率的提高,襯墊的成膜性能也有所提高,表明甘油醚接枝改性改善了自潤滑關(guān)節(jié)軸承的摩擦學(xué)性能。
[Abstract]:Because the phenyl group of aramid material is very difficult to dissolve in most chemicals, the self-lubricating pad and adhesive made from PTFE-PTFE fiber and aramid fiber have poor adhesion properties. In order to affect the overall performance of the bearing, the self-lubricating pad of joint bearing was modified by glycerol ether grafting, and the tribological properties of the modified bearing were measured by tribological dynamic performance test machine. The results show that the wear, friction coefficient and friction temperature rise of the bearing after the modified treatment are obviously reduced. After the grafting modification, the film forming performance of the liner was obviously improved, and with the increase of swing frequency, the film forming performance of the liner was also improved. The results showed that the tribological properties of self-lubricating joint bearings were improved by glycerol ether graft modification.
