摘　　要：在冶金机械设备中，大量使用变速传动系统，即减速机和增速机。变速传动箱是一个密闭的箱体，箱体上的排气装置往往会被人们忽视，排气装置能排出箱体内产生的热量和气体、水蒸气，同时又避免外部粉尘进入，从而降低了箱体内的温度和产生的气体压力，保护各种零部件，如轴承、密封件，延长它们的使用寿命，也避免葙体内产生的水蒸气附着在设备上，造成设备的锈蚀。Variable speed drive systems, i.e. speed--decreasing and speed-increasing machines, are widely used in metallurgical machinery. Variable speed drive boxes are closed boxes. Exhaust devices in the boxes are always ignored by people. The exhaust devices can expel heat, gas and steam arose in the boxes and prevent outside dust from going into the boxes, so as to reduce temperature and pressure in the boxes and protect various parts such as bearing and sealing and prolong service life of the parts and prevent steam from clinging on the parts to avoid their corrosion.
