| Abstract：The swelling characteristics，friction and wear behaviors of nitrile-butadiene rubber（NBR）and fluoropolymer（FPM） in the mixture of of cyclohexane and base oil（20# engine oil） were studied.The results showed that，in cyclohexane mixture solution，with the increase of immersion time，the mass，hardness and modulus of elasticity of NBR changed greatly，but those properties of FPM changed little. With the increase of cyclohexane ratio in the mixture or load，the frictional wear amount and friction coefficient of NBR and FPM increased，and the load of the fast frictional wear transition point of FPM was greater than that of NBR. When the cyclohexane ratio and the load was small，the wear of FPM was very light，but NBR could be used since its cost was lower. When the cyclohexane ratio or the load became large，FPM should be selected for stator rubber due to its better performance. |
