我厂井式渗碳炉上的风扇叶,使用一段时间后,风扇叶与风扇轴的配合就松了。为了解决这一问题,我们根据风扇叶和风扇轴间隙的大小,利用渗碳炉上坏了的废热电偶不锈钢管,按要求在车床上加工到一定的壁厚,然后将加工好的不锈钢管用手锯沿纵向割成三等分,再用手锤在平板上敲平成长片状,均放在风扇叶的内孔上,再和风扇轴装配好后用螺帽压紧,每次休班后便换垫片一次,这样 I plant pit type carburizing furnace fan leaves, use for some time, the fan blades and fan shaft with the loose. In order to solve this problem, according to the fan blade and fan shaft gap size, the use of carburizing furnace broken waste thermocouple stainless steel tube, according to the requirements of the lathe machining to a certain thickness, and then the processed stainless steel tube Cut the hand saw along the longitudinal cut into three equal parts, and then hand hammer on the flat plate knocked flat growth, are placed in the fan blade hole, and then assembled with the fan shaft with a nut compression, each shift off After changing the gasket once, so
