通常当烘缸轴颈严重损坏需修复时,必须通过拆卸起吊,然后在大型立式或卧式车床上进行加工,再装配、试压、起吊上机。这样的修理方法不仅耗资大,修复周期长,而且严重影响生产。我厂直接在纸机上加工直径为3米的烘缸轴颈获得成功,为迅速恢复生产创造了条件。其办法如下: 一、加工烘缸轴颈的方法和步骤(见图1) 先将轴承1切去轴瓦全长的3/5和半径的2/5,即切去图1中轴瓦的虚线部份,然后固定在用钢板焊接成带有偏心的轴承座2上,改制成的原轴瓦必须和
Usually when the drying cylinder journal serious damage to be repaired, it must be removed by lifting, and then in a large vertical or horizontal lathe for processing, reassembly, pressure test, lifting machine. This repair method is not only expensive, long repair cycle, but also seriously affect the production. I plant directly on the paper machine diameter of 3 meters drills journal success, for the rapid restoration of production to create the conditions. The method is as follows: First, the method of drying cylinder journals and steps (see Figure 1) First bearing 1 cut off the full length of the bearing 3/5 and 2/5 of the radius, that is, Parts, and then fixed in the steel welded with eccentric bearing 2, converted into the original bearing must and
