Abstract

Abstract: The continuous generating gear grinding, cgg, is an essential process to efficiently manufacture gears that have low noise in operations. However, the intense heat generation in the process could deteriorate the gear surface. Thus, it is crucial to know the mechanism of the heat generation to improve the process. In this study, we proposed a way to directly measure instantaneous rise of temperature on a gear surface using a fully embedded data logger and an eroding thermocouple despite its complicated kinematics. The temperature rise was revealed to be related to the transition of the depth of removal at each moment through the developed kinematic simulation.
