CAE Analysis for Oil Leakage Mechanism of Transaxle Oil Seal
IOSR Journal of Computer Engineering
In recent years, the authors have been conducting research on the establishment of technical prevention measures for automobile development and design. This research investigates the mechanisms that cause oil leaks in drive train oil seals, which are a matter of concern for automobile manufacturers around the world. In the case of automobile transaxle oil seals, the edge of the seal's rubber lip is in sliding contact with the surface of the drive shaft, and the seal serves to prevent the
... prevent the lubricating oil sealed inside the drive gearbox from leaking to the outside. In this paper, the authors take up the example of analyzing the mechanisms by which oil leaks caused by wear of drive train oil seals. In order to demonstrate this, the authors incorporated a model of the oil film on sliding surfaces and simulated the oil seals' sealing performance. The authors also incorporated the analysis model for CAE, combining a fluid model, an oil seal sliding surface model, and methods such as the finite element method. Thus, the authors contributed to establishing technical prevention measures for automobile development and design utilizing CAE.
