1米~3挖掘机的铲臂升降卷扬机构,是由蜗轮蜗杆组成的。在大修期间,我们拆开检查,发现担负铲臂上升的蜗轮轮齿那面磨损严重,本应更换蜗轮,但我们发现,承受铲臂下降运行的蜗轮轮齿面,没有什么磨损,尚能使用,于是我们决定将蜗轮调边使用。其加工工艺很简单,先 1 m ~ 3 excavator shovel arm hoist lifting mechanism is composed of worm gear. During the overhaul, we disassembled the inspection and found that there was serious wear and tear on the gear surface of the worm gear that was responsible for the ascent of the shovel arm. We should replace the worm gear. However, we found that there is no wear and tear on the gear surface of the worm gear that is subjected to the descending operation of the shovel arm. , So we decided to adjust the use of the worm gear. Its processing technology is very simple, first
