摘　　要：在各种液压系统和机械旋转传动系统中,为防止空气渗入对系统造成负面影响,其大部分系统中都有密封装置,如液压缸中的轴密封、中速磨煤机中托盘的轴密封等。针对磨煤机中托盘轴设计一种密封装置,该装置是可使托盘在旋转的过程中防止空气从托盘轴的周围进入磨煤机的内部使其含氧量达到煤粉的自燃范围。In various hydraulic systems and mechanical rotary driving systems, in order to prevent negative impact of air infiltration on the system, most of systems have sealing device, such as the shaft sealing of hydraulic cylinders and the shaft sealing of the middle - speed mill＇s tray. In the article, the shaft sealing device is designed for the tray of mill. The sealing device is used to prevent the air from the tray into the mill in the process of rotating to meet the oxygen content＇s scope of spontaneous combustion.
