Y38滚齿机的工作台分齿蜗杆处漏油严重。分齿蜗轮箱中加满油,一星期就漏光。操作工人不经常注意观察油标,蜗轮副就会被咬死,严重地损坏机床的精度。我们拆下蜗杆联接套,发现这联接套中间是通孔(右图)。套的一头联接传动轴;另一端联接分齿蜗杆,由于工作台分齿蜗轮副是浸在油里。在机床开动过程中,油慢慢地通过键槽间隙渗出。针对这一现象,我们将分齿蜗杆联接套改为一个中间不通的两端分别插键槽的零件(左图),这样油就不会从键槽中漏出。但要求两端的孔必须保持同轴度
Y38 hobbing machine table worm gear at the Department of serious oil spills. Sub gearbox filled with oil, a week on the light. Operating workers do not often observe the oil standard, worm gear will be killed, a serious damage to the accuracy of machine tools. We removed the worm coupling and found that the middle of this coupling was a through hole (right). Set of a joint drive shaft; the other end connected to the sub-worm, the table sub-worm gear is immersed in oil. During the start-up of the machine, the oil slowly bleeds through the keyway clearance. In response to this phenomenon, we will change the worm gear coupling sleeve into a non-through the two ends of the keyway parts (left), so that oil will not leak from the keyway. However, the holes on both ends must be concentric
