| Outline of Final Research Achievements |
Recently, natural materials are utilized to focus on the ecological recycling. The rice hull is a residual product of rice and it contains natural silica about 20wt.%. The Rice-Hull-Silica-Carbon (RHSC) is a carbonized rice hull, and is a high strength porous carbon material. We try to used the RHSC as a reinforcing material in plastic crossed herical gears.
In this study, some median grain diameters and some dopant ratios of RHSC-powder were prepared for the strengthen-injection-molded plastic herical gear. Then, the fatigue test of crossed herical gears was carried out measuring the bulk temperature. Especially, the effects of RHSC powder on the friction properties were discussed to improve the fatigue strength of the injection-molded plastic crossed herical gears.
