W-1002挖掘机推压部分推压轴是采用铜瓦支承,并用螺栓紧固在鞍座上。我矿在使用中,经常发生螺栓被剪断的现象,有时一个班竟达4、5次之多。从1976年开始到1977年底,我们陆续将全矿8台电铲的滑动轴承改为3524双列向心球面滚动轴承(附图)。 W-1002 excavator push part of the push shaft is supported by copper tile, and bolted to the saddle. My mine in use, often the phenomenon of bolts are cut, and sometimes a class as many as 4,5 times. From 1976 to the end of 1977, we gradually changed the plain bearings of 8 electric shovels in the whole mine to 3524 double row radial spherical roller bearings (with photos).
