事件描述

该索道为单线循环固定抱索器脉动式8人吊厢索道,全长1858米,高差 837米,每小时运量400人,索道于2011年7月1日建成运营。

索道在正常运营中,下站突然出现间断性不规则声音:

处理过程

1.由于该索道于2019年1月6日-7 日更换了辅机轴承;暂且认为辅机轴承没有问题;

2.将辅机电机与减速机吊离至设备大架上,试运行声音依然存在;

3.将辅机轴承座与主机分离,试运转;声音消失;

4.通过以上两步检查排除了驱动轮轴承异响的可能,基本确定为辅机轴承座异响,或辅机齿轮与驱动轮齿圈接触面异响;

5.对辅机齿轮与驱动轮齿圈进行了检查发现,齿面磨损严重;

6.对齿面进行了修复之后,异响消失。

其他检查

检查辅机齿轮与驱动轮齿圈,经检查发现齿面磨损严重。

辅机齿轮表面

驱动轮齿圈表面

分析

索道辅机齿轮与驱动轮齿圈一直处干联动状态,截止目前为止已经运行了8年之久;该索道在齿面使用的润滑脂是普通锂基脂,其附着力较低,不能对齿面形成长时间的保护,导致齿面磨损比较严重;而且长时间的啮合运行,导致两齿轮之间形成了“唯一的啮合点”,在近期的一次维修完毕后没有找准“唯一的啮合点”,导致齿轮啮合不到位,且随着齿面润滑脂的不断减少,而产生异响。

结论

对于长期啮合的外露齿轮,因选择粘性较大的外齿轮专用油,并定期清洗润滑;避免齿轮的过度磨损和形成“唯一的啮合点”。
