一、故障的判断及处理 1997年6月,云岗矿北部提升机有异响,我们对提升系统各部进行了运行分析。当时迹象为:（1）提升机运行过程中发出周期性的响声;（2）上、下车响声出现时,滚筒转的位置不同;（3）用手触摸提升机轴承座,能感觉到有周期性的周向力,并且上、下车时其力的方向不同。产生周向力的只能是减速器的斜齿或人字齿轮,所以初步判断减速器有部分齿断裂。从减速器观察孔检查,发现大齿轮有一齿断裂,开盖起吊大齿轮,发现齿圈有三处明显断裂,而与其啮合的齿轮没有任异常。更换一套大齿轮后,提升机恢复生产。
First, the failure to determine and deal with In June 1997, Yungang mine hoist abnormal sound north, we have to enhance the system of the Ministry of operation analysis. At that time, the signs were: (1) cyclical sound was emitted during the operation of the hoist; (2) the positions of the drums were different when the squeaking noise appeared; (3) the bearing seat of the hoist was touched by hand and felt Periodic circumferential force, and get off the force of the different directions. Produce a circumferential force can only be the helical gear reducer or herringbone gear, so the initial judgment of the gear reducer has some teeth. Inspection from the reducer hole inspection and found a large tooth gear rupture, open lifting gear, found that there are three obvious ring gear fracture, and the meshing gear without any abnormalities. After replacing a large gear, hoist to resume production.
