在机械工业产品中,各种机器大多采用推力滑动轴承零件。这种零件是在轴承套的一端或两端带有台肩式的止推边,它的作用是,工作轴在负荷旋转时,防止轴沿轴向移动。我厂生产的双金属轴瓦(图1),采用 In mechanical industrial products, most of the machines use thrust sliding bearing components. Such parts are provided with a shoulder-type thrust edge on one or both ends of the bearing housing, which serves to prevent the shaft from moving in the axial direction when the load shaft is rotated. I plant the production of bimetallic bearings (Figure 1), adopted
