我公司在生产中经常遇到各种大、中型减速机、齿轮机、变速箱膛孔因磨损而被迫停机的情况,为快速修复缩短停机时间,我们摸索出“焊垄条刮研法”进行修复,做到了省力、省时、速度快,并能确保焊补质量。现将这一方法介绍如下:1.先将要修复的膛孔清洗干净,并用氧-乙炔焰烘烤,烧去表面的油污,并预热到250℃左右。2.用手砂轮在膛孔面上开成条形沟槽,沟距为15～18毫米,沟深 Our company often encounter in production all kinds of large and medium-sized reducer, gear machine, gearbox bore was forced to shut down due to wear and tear, to quickly repair and reduce downtime, we worked out “welding ridge scraping method” To repair, so that labor-saving, time-saving, fast, and to ensure welding quality. Now this method is introduced as follows: 1 first to be repaired bore clean, and baking with oxygen - acetylene flame, burn the surface of the oil, and preheated to about 250 ℃. 2 hand wheel in the bore surface opened into a strip groove, trench spacing of 15 ~ 18 mm, ditch deep
