| Outline of Final Research Achievements |
Power transmission system using gears require both large capacity and miniaturization. As a result, the gears used in power transmission need to be strong enough to withstand high loads and high engine speeds. Because surface damage and temperature are related, it is very important to know the surface temperature of gears in operation. In this study, we succeeded in measuring the temperature of the tooth surface under high contact pressure by dynamic thermocouple with dissimilar hardened gears, and it was possible to clarify the prediction method also. It was able to contribute to the advancement of the gear design method in the future.
