The temperature rises by friction exothermic reaction and hysteresis exothermic reaction between tooth surfaces, elastic modulus lowers on the allowable stress of the plastic gear material, and the allowable stress lowers. Then, the strength of the tooth weakens on the face width central, since the heat radiation effect lowers. This study is the verification result between analytical result and experiment of developed plastic gear exclusive use exothermic reaction and heat conduction three-dimensional analysis software. Then, the simulation by the difference between the face width is carried out, and it is shown that it obtains allowable stress from the temperature distribution of the tooth and that the strength of plastic gear is not proportional to the face width.
