五矿矿业昌邑郑家坡铁矿有限公司的选矿厂球磨机与高压同步拖动电机间的连接,为气动离合器方式,正常运行中突然出现滑动轴承窜动幅度比较大并且烧轴瓦。为此,本文分析了高压同步电机和被拖动球磨机间采用气动离合器联接时,滑动轴承型电机转子轴向窜动产生的原因,提出了具体解决办法与改进措施。
Minmetals Changyi Zhengjiapo Iron Ore Co., Ltd. beneficiation mill ball mill and high-voltage synchronous drag motor connection between the pneumatic clutch mode, the normal operation of a sudden sliding bearing movement range is relatively large and burning bearing. Therefore, this paper analyzes the reasons for the axial run-in of the rotor of the sliding bearing motor when the pneumatic clutch is connected between the high-voltage synchronous motor and the driven ball mill, and puts forward the specific solutions and improvement measures.
