摘要：

For saving energy and resources, the spheroidal graphite cast iron is tentatively used as gear material. It has many advantages in manufacturing and physical properties. New materials - 3 kinds of JIS FCD60 by various heat treatments and as-cast FCD70 - are produced by way of trial. From the machinability test of these materials by turning, it is clear that the as-cast FCD70 has the best machinability in terms of cutting force and tool life. Second, the hobbing tests reveal that the as-cast FCD70 is much superior in hob wear and tooth surface roughness to hardened and tempered steel. Third, the surface fatigue testing machine. It indicates that the pitting fatigue life of the ascast FCD70 is longer than that of hardened and tempered steel.
