工艺要点:

1、拆除风道保温。

2、拆除挡板轴支承轴承的端盖。

3、清洗轴承室。

4、检查支承轴承。

5、轴承添加新润滑油脂并回装。

6、检查轴与轴套磨损量,重新润滑并回装。

7、检查挡板门轴是否平直,应无变形弯曲等缺陷。

8、检查挡板曲臂应无变形,与挡板轴连接处焊口无裂纹。

质量要求:

1、轴承应无锈蚀、麻点、沟槽、过热变色等缺陷。

2、轴套磨损超过原厚度的2/3时应更换。

3、挡板与转动轴固定良好、无松动,传动轴密封良好。

4、挡板叶片磨损超过原厚度的1/2时应更换,转轴磨损不超过2mm。

5、挡板四周间隙在3mm~5mm之间,轴承游隙符合GB/T 4604.1的规定。
