100Cr6轴承材料摩擦磨损试验研究

基于Archard磨损理论公式,针对100Cr6轴承材料的摩擦学性能开展实用性试验研究,测试其在干摩擦条件下的摩擦磨损性能,研究100Cr6材料的摩擦因数、磨损深度、试件温度、磨损量随法向载荷和滑动直径的变化规律。研究表明:摩擦因数随法向载荷和滑动直径的增大而增大,当法向载荷较小时,滑动直径对摩擦因数影响较小,当法向载荷较大时,影响较大;磨损深度随法向载荷的增大而增大,随滑动直径的增大而减小;法向载荷对试件温度有正影响作用,滑动直径越大,试件温度越高;磨损量随滑动直径的增大而减小,当滑动直径较小时,法向载荷对磨损量具有明显的影响。

Experimental research on friction and wear of 100Cr6 bearings

A practical experimental research on the tribological properties of 100Cr6 bearings material was carried out to test its friction and wear properties under dry friction conditions based on Archard's wear theory formula.The variation of friction coefficient,penetration depth,specimen temperature and wear loss with normal load and sliding diameter of 100Cr6 bearing material was studied.The results showed that the friction coefficient increased with the increase of normal load and sliding diameter.When the normal load was small,the sliding diameter had little influence on the friction coefficient.But when the normal load was large,the influence was greater.Penetration depth increased with the increase of normal load,but decreased with the increase of sliding diameter.The normal load had a positive effect on the specimen temperature.The specimen temperature increased with the increase the sliding diameter.The wear loss decreased with the increase of sliding diameter.The normal load had an obvious effect on wear loss,when the sliding diameter was small.
