为了探讨硬度对钢蜗轮副材料磨损行为的影响,为研究钢蜗轮副合理的硬度配对提供试验依据。通过不同的热处理工艺,使12Cr2Ni4低碳合金钢获得了5种不同硬度的试样,然后在无润滑,室温条件下,在SRVⅣ微动磨损试验机上考察了硬度对12Cr2Ni4钢-18Cr2Ni4WA钢摩擦副磨损行为的影响。结果表明:试验条件下,随着12Cr2Ni4钢硬度的增加,12Cr2Ni4钢的磨损体积减小,其偶件18Cr2Ni4WA钢的磨损体积增大,当12Cr2Ni4钢硬度位于HRC39-HRC41之间时,摩擦副双方的磨损量相等;12Cr2Ni4钢的相对耐磨性和摩擦系数都随12Cr2Ni4钢硬度的增加而增大,最大的相对耐磨性和摩擦系数的最大值均约为0.9。
In order to study the effect of hardness on the wear behavior of steel worm gear pair, the experimental basis was provided to study the reasonable hardness matching of steel worm gear pair. Through different heat treatment process, five different hardness samples of 12Cr2Ni4 low carbon alloy steel were obtained. Then, the wear resistance of 12Cr2Ni4 steel-18Cr2Ni4WA steel on the SRVIV fretting wear tester was studied under the condition of no lubrication and room temperature. The impact of behavior. The results show that with the increase of hardness of 12Cr2Ni4 steel, the wear volume of 12Cr2Ni4 steel decreases and the wear volume of 18Cr2Ni4WA steel increases even when the hardness of 12Cr2Ni4 steel is between HRC39 and HRC41 The wear resistance and friction coefficient of 12Cr2Ni4 steel all increase with the increase of hardness of 12Cr2Ni4 steel. The maximum relative wear resistance and friction coefficient are all about 0.9.
