主轴承烧粘是磨机较为常见的故障之一。磨机主轴承一旦 发生烧粘,不但会使轴瓦的锡基合金层严重磨损,降低轴瓦的使用寿命,而且会使磨机的运转率大大降低,直接影响生产任务的完成,造成巨大的经济损失。造成磨机主轴承烧粘的原因比较复杂,笔者从以下几个方面进行阐述。 1 原因分析 （1）制造及安装质量不佳 磨机关键部位的制造加工控制不严及安装质量不高是造成磨机主轴承烧粘的重要原因。在制造方面,磨机筒体在加工时壁厚太薄,刚度不够,造成筒体下挠
Burn the main bearing is one of the more common failure of the mill. Once the main bearing of the mill burns, the tin-based alloy layer of the bearing bush will not only wear seriously, but also reduce the service life of the bearing bush, and will greatly reduce the operation rate of the mill and directly affect the completion of production tasks, resulting in huge economic losses . The main reason for burning mill main bearing adhesion is more complicated, I elaborate from the following aspects. Analysis of the reasons (1) manufacturing and installation of poor quality Manufacturing and processing of key parts of the mill is not strict control and installation is not high quality is the main cause of sintering mill main bearing. In manufacturing, the mill barrel in the processing of the wall thickness is too thin, not enough rigidity, causing the cylinder down
