阜新平安矿配用HKM31×4×2.5型及2JK-3/11.5型绞车的YR系列电动机,原是滑动轴承结构,存在以下缺点:1.一般巴氏合金瓦磨损快、寿命短,更换频繁,故障多;2.检修换瓦的工期长,劳动强度较高;3.传动阻力大;4.不易维护检修,若刮研瓦或安装稍微达不到要求精度以及润滑跟不上时,就将发生高温烧瓦等故障而影响生产。为解决这些问题,自七八年以来,我们先后将YR630-12/1430(630千瓦)及YR500-16/1430(500千瓦)电动机改为滚动轴承结构,运转至
Fuxin Ping’an mine equipped with HKM31 × 4 × 2.5 and 2JK-3 / 11.5 winch YR series motors, the original sliding bearing structure, the following shortcomings: 1. General Babbitt wear fast, short life, frequent replacement, Failure and more; 2. Maintenance for a long duration of the replacement of labor, higher labor intensity; 3. Transmission resistance; 4. Difficult to maintain maintenance, if scraping watts or install slightly less than the required accuracy and lubrication can not keep up, will be The occurrence of high temperature burning tile and other failures affect the production. To solve these problems, we have changed the YR630-12 / 1430 (630kW) and YR500-16 / 1430 (500kW) motors to the rolling bearing structure successively since 1978, operating to
