蜗轮减速器使用上存在的问题是:外壳容易破裂(联结螺栓的座孔破裂);蜗轮和蜗杆的使用寿命短,一般在3—5个月。操作时(上钎和升落大架子时)减速器内冒烟、漏油等。减速器外壳原设计材质是生铁,每台穿孔机每年要更换1～2个。我们考虑其强度不够,从1958年起改用铸钢,从此没有再发生过破裂;蜗轮蜗杆的使用寿命短以及操作时冒烟,主要原因是设计时选择材质不合理,蜗杆的材质是45钢,蜗轮材质是45铸钢。我们在1959年用锡青铜制造了8个蜗轮试用,1964年8月份检修时拆开检查有两
There are problems with the use of worm gear reducer: the shell is easy to break (the coupling bolt hole cracked); worm gear and worm service life is short, usually in 3-5 months. Operation (on the brazing and when the big shelf lift) smoke, oil spills and so on. Reducer shell The original design material is pig iron, each piercer to be replaced every year 1 or 2. We consider its strength is not enough, from 1958 to switch to cast steel, there has been no rupture; worm gear life is short and smoke during operation, the main reason is the choice of design material unreasonable, the worm is made of 45 steel , The worm gear is 45 cast steel. We made a trial of eight worm wheels made of tin bronze in 1959. In August 1964, we had two
