摘要
研究了Honda某型号CVT（无极变速箱）带轮在不同热处理工艺时各渗碳层情况下的磨损状况。通过金相组织分析、硬度分析、扫描电镜及能谱分析,获得了不同渗碳层深度、含碳量时带轮的硬度变化及磨损规律。结果表明,渗碳层深度在0.5~0.8 mm,表面硬度在HRC58~62时,带轮的磨损量最小,具有最佳的抗磨损性能。
A Honda CVT（ continuously variable transmission） pulley deformation conditions with different depth of carburizing layer under different heat treatment process were analyzed. Through metallographic analysis,hardness analysis,spectrum analysis and scanning electron microscope,the wear and hardness change rules of the pulley with different depth of carburized layer and different carbon content were gained. The results show that the depth of carburized layer in 0. 5 ~ 0. 8 mm,the surface hardness of HRC58 ~ 62,pulley wear is minimal,and with the best wear resistance.
