摘要

为了提高高速齿轮箱密封装置的密封性能，对常用于石油、化工等领域中的高速齿轮传动装置的非接触式迷宫密封进行了分析。通过建立（Computational fluid dynamics，CFD）数值计算模型，分析了该密封装置的密封齿数量、密封压差、油气混合物浓度、甩油环位置等因素对各密封腔回油口回油量及漏油口泄漏量的影响。研究对高速齿轮箱用非接触式迷宫密封的设计具有指导意义。

Abstract

In order to improve the sealing performance of the high-speed gearbox sealing device， this study analyzes the non-contact labyrinth sealing of the high-speed gear transmission commonly used in petroleum， chemical and other fields. By establishing a numerical calculation model， the influence of factors such as the number of sealing teeth sealing differential pressure， oil-air mixture concentration，and position of oil slinger on the leakage of oil return ports and oil leakage ports of each sealing cavity is analyzed， which has guiding significance for the design of non-contact labyrinth sealing for high-speed gearboxes.
