皮带车床的主轴,在运转中前后轴承经常受到磨损,在磨出1～1.5公厘的深沟时,就很难修理了。过去一般是重换新主轴或换铜瓦,这样不但浪费金属材料,并且影响生产进度。后来动力车间工人刘焕阁同志,改进用镶套的办法来修复废主轴。改进的办法很简单,即在主轴磨损处镶钢套。先将主轴磨损处车光,再按主轴磨损处的尺寸(公差0.2左右)配制一个钢套。这钢套用5号纲制成。然 Belt lathe spindle, before and after operation in the bearing often subject to wear, wear out 1 ~ 1.5 mm deep groove, it is difficult to repair. The past is usually to replace the new spindle or change copper tiles, so that not only a waste of metal materials, and affect the production schedule. Later, Liu Huange, a power shop worker, improved the method of setting the waste shaft with a set of inserts. The solution is simple, with a steel sleeve on the spindle wear. The first spindle wear at the car, then wear the spindle size (tolerance of about 0.2) preparation of a steel sleeve. This steel sleeve made of No. 5. Of course
