三、四年前作者改进了一种方法来测量齿轮传动辊子疲劳试验机全面进磨法样品的温度。这一基于一个热电偶小球“悬浮”在工件表面冷却液形成的液体薄膜上的技术对齿轮传动试验机和使用油类冷却液的全面进磨法非常有用。水溶油性冷却液虽然比油类液更薄,但是形成的液体薄膜没有可以支持热电偶小球的足够粘度。 Three or four years ago, the author improved a method to measure the temperature of a fully-worn sample of a gear-driven roller fatigue tester. This technique, based on a thin film of a thermocouple bead “floating” on a liquid film formed by a coolant on the surface of a workpiece, is very useful for gear-driven testers and full grinding methods using oil coolants. Although the oil-soluble coolant is thinner than the oil, the resulting liquid film does not have enough viscosity to support the thermocouple beads.
