We tested poly butylene telephthalate (PBT) as a gear material in our previous study and found that it had larger fatigue strength and lower coefficient of friction than those of polyacetal used as a gear material currently. In the present study, since plastic gears that can transmit high power have been strongly demanded by the industrial world, we reinforced PBT by compounding grass fibers for higher power transmission than normal PBT and conducted operation tests on gears made of reinforced PBT. Wear behavior was particularly investigated under a relatively larger torque since plastic gears filled with grass fibers were expected to be worn significantly due to a fall of grass fibers from the mother material. Availability of PBT filled with grass fibers for a gear material was discussed by comparing basic operational characteristics with those of normal PBT gears.
