我厂 GX型螺旋输送机总长约 1 000m，悬挂轴承总计约 330多个。改进前悬挂装置结构如图 1，主要问题是：密封毛毡磨损失效，大部分密封盖被磨成不规则圆形，吊瓦盖磨损严重，且中间磨损少，两侧磨损较多，联接轴磨损相当严重，磨损宽度大于吊瓦盖宽度。分析认为，螺旋轴工作?
I plant GX-type screw conveyor total length of about 1 000 m, a total of about 330 suspension bearings. Improve the structure of the front suspension shown in Figure 1, the main problems are: sealing felt wear failure, most of the seal was ground into an irregular round, hanging tile cover serious wear and tear, and less wear on both sides, both sides wear more, the coupling shaft wear Very serious, wear width is greater than the width of the hanging tile cover. Analysis, the screw shaft work?
