我厂铸钢车间使用的Q3113A清理滚筒,其双列向心球面轴承的两端均采用毛毡填料密封。随着填料磨损,间隙增大,粉尘和铁丸进入轴承,造成轴承磨损,甚至出现轴承卡死,致使滚筒无法正常工作。因此,我们对轴承密封结构进行了如图所示的改进。将原轴承座与抽承盖进行切削加工改制,在轴承座加工的端面上攻6只M10螺孔,配置端盖;轴承盖和端盖内加装J型骨架橡胶密封 Q3113A cleaning cylinder used in our steel plant, both ends of double row radial spherical bearings adopt felt packing seal. With the filler wear, the gap increases, dust and iron balls into the bearings, resulting in bearing wear and tear, or even stuck bearing, resulting in the drum can not work properly. Therefore, we have made improvements to the bearing seal structure as shown. The original bearing and the bearing cover for cutting transformation, in the bearing surface processing attack on the end of 6 M10 threaded hole configuration end cover; bearing cap and end cap with J-shaped skeleton rubber seal
