我校办工厂经常使用Ｃ6 2 0 -1车床加工铸钢件。在车削工件端面时 ,图 1中横向走刀齿轮 3的右端和法兰套 5的左端磨损严重 ,因为在加工工件时 ,横向走刀齿轮和法兰套的两端面承受轴向力较大。 在维修车床时 ,我们将齿轮右端和法兰套左端 ,共车去一个推力轴承的厚度 ,或者单
Our school-run factories often use C620-1 lathe to process steel castings. When turning the end face of the workpiece, the right end of the horizontal guide gear 3 and the left end of the flange sleeve 5 in FIG. 1 are worn seriously. Because both ends of the horizontal guide gear and the flange sleeve are subjected to larger axial forces when machining the workpiece. In the maintenance of the lathe, we will gear the right end and the flange left side of the car to go to a thrust bearing thickness, or single
