轮毂在使用过程中,由于路况恶劣等原因,容易发生轮毂轴承外圈在轮毂轴承座孔内松旷,轮毂轴承温度升高,轮毂轴承内润滑脂因熔化为液体而流出,以致轮毂轴承烧坏。笔者采用普通低碳钢焊条E4303对轮毂轴承座孔进行了堆焊修复,既节约了资金,又解决了某些特殊轮毂因一时买不到而导致车辆停运的问题,受到了客户的好评。1 轮毂材料及其焊接性轮毂材料一般为球墨铸铁QT450-10,这类球墨铸铁以铁素体为基体(称为铁素体球墨铸铁),其抗拉
Hub in use, due to poor road conditions and other reasons, prone to hub bearing outer ring in the hub bearing hole loose, hub bearing temperature, grease in the hub bearing due to melt and liquid flow out, resulting in hub bearing burnout . I used ordinary low carbon steel electrode E4303 bearing hub hole drilled to repair, not only saves money, but also to solve some of the special wheels can not be bought for a while due to the problem of vehicle outage, praised by customers. 1 hub material and its weldability Wheel hub material is generally ductile iron QT450-10, this type of ductile iron to ferrite matrix (called ferrite nodular cast iron), the tensile
