Abstract
For mechanical friction loss reduction, the specific pressure of sliding parts or contact surfaces is increasing. For this reason, the problem of wear and damage has occurred according to change to worse of lubrication condition. In order to solve this phenomenon, it is important to get to know temperature distribution, and the sensor which measures temperature, such as machine sliding surfaces and a contact surface, with high precision is needed. This research described the feature of each material from comparison of the form and pressure sensitivity of a thin film type temperature sensor, or temperature sensitivity which used platinum and titanium. Moreover, the example of formation to the gear tooth flank was shown as an example of attachment of a sensor.
