我厂轧钢车间φ280mm成品单带轧机齿轮箱1986年5月初检查时,短八字齿轮轴安装轴承部位磨损严重,如图1所示。图中1处磨损量为0.10mm,2处磨损量为0.20mm。这样,与轴承内圈装配间隙太大,不能正常使用。为此,应用热喷涂技术进行修复。 1.具体方法设计涂层0.35mm,即将该件1、2部位用车床车削成φ149.30mm,部位3细螺纹处用调好的广告粉涂一层,保护好。先后将1、2部位用喷枪预热到100℃(车床转速调到3O I plant rolling mill φ280mm finished single with a rolling mill gear box in early May 1986 inspection, the short letter gear shaft mounted bearing parts worn seriously, as shown in Figure 1. Figure 1 wear a 0.10mm, 2 wear 0.20mm. In this way, the bearing assembly with the inner ring gap is too large, can not be used normally. To this end, the application of thermal spray technology to repair. 1. The specific method of design coating 0.35mm, about the 1,2 parts of the lathe turned into φ149.30mm, part 3 fine thread with good advertising powder coated, protected. 1,2 parts have been preheated with a spray gun to 100 ℃ (lathe speed transferred to 3O
