一、转轮迷宫环处理设备我厂3号机HL702-410型转轮上、下迷宫环磨损严重,需要进行处理。由于上、下迷宫环是直接由转轮上、下环车制而成,而不是通常所采用的那种将迷宫环预先做好,而后热套于转轮上的。这样就造成迷宫环损坏后,不能更换新品。由于转轮重42吨,外形尺寸为φ4625×2153毫米,运往外地加工,时间不允许,只好自己想法处理。处理的方法是:用手工电弧焊将迷宫环磨损处补焊好,然后依靠专用工具进行铣削。铣削工具包括两种部分:π型旋转架和铣削头。在转轮中心处穿一长约1.9米的心轴,其下端用球面滚珠轴承固定于承重钢梁上;在 First, runner labyrinth ring processing equipment I plant No. 3 HL702-410 runner, the lower labyrinth ring wear and tear, need to be processed. Because the upper and lower labyrinth ring is directly from the runner, the lower ring made of the car, rather than the kind of labyrinth usually used in advance, then the heat in the runner. This will result in damage to the labyrinth ring, you can not replace the new product. As the runner weighs 42 tons, the overall dimensions of φ4625 × 2153 mm, shipped to the field processing, time is not allowed, had to deal with their own ideas. The treatment is: manual arc welding will wear the labyrinth ring welding repair, and then rely on special tools for milling. Milling tool consists of two parts: π-type rotating frame and milling head. In the center of the wheel to wear a mandrel about 1.9 meters long, the lower end of the spherical ball bearing fixed to the load-bearing steel beam; in
