Then using this tester, the effect of the sum of surface speed and slip ratio on the friction coefficient and load carrying capacity of the oil films generated between point contact can be evaluated by the wear conditions of the tested specimens under elastohydrodynamic conditions. The experimental results show that the increase in sliding-rolling ratio and the sum of surface speed not only caused the friction coefficient between specimens to decrease, but also caused the specimens to be worn more easily. This result means that the load carrying capacity of the oil film decreases as the sliding-rolling ratio and the sum of surface speed between two disc specimens in elliptic contact increases. 蘇侃 2008 學位論文 ; thesis 64 zh-TW |
