我厂2~#20t/h锅炉中修,在拆卸炉排传动减速器(J300)时,因吊装不慎,箱盖轴承孔的边缘被撞下二块50×10mm的碎块,断裂位置如图1所示。通常,解决的方法是:(1)调换外购箱盖。(2)机械修复。但是,如此大型箱盖,订购周期长,若整套减速器一同购买,费用太高,近2万元,且一时也供应不上。用机械修复,不仅加工周期长,而且漏油问题不易解决。显然,常规方法不能解决。在无备件又亟待解决的情况下,采用粘接技术进行修复。
I plant 2 ~ # 20t / h boiler repair, demolition Grate drive reducer (J300), due to improper lifting, cover the edge of the bearing hole was hit two 50 × 10mm pieces, rupture position such as Figure 1 shows. In general, the solution is: (1) exchange of outsourcing cover. (2) mechanical repair. However, such a large lid, long ordering cycle, if the entire set of reducer with the purchase, the cost is too high, nearly 20,000 yuan, and temporarily not available. With mechanical repair, not only the processing cycle is long, but the problem of oil leakage is not easy to solve. Obviously, the conventional method can not be solved. In the absence of spare parts and urgent solution, the use of adhesive technology to repair.
