目前国内大型磨机的主轴承大多选用滑动轴承。一般情况是磨机的出料端为固定端,进料端为浮动端,即出料端的轴承宽度与中空轴上的间隔开档紧密配合,保留了3mm 左右(视磨机规格大小而定)的运动间隙,以限定磨机的轴向位置,防止磨机运转时窜动。进料端的轴 At present, most of the major domestic mill bearings use plain bearings. Generally, the discharge end of the mill is a fixed end, the feed end is a floating end, that is, the width of the bearing at the discharge end closely matches that of the hollow shaft, and retains about 3 mm (depending on the size of the mill) Of the movement gap to limit the mill’s axial position, to prevent the mill from running.
