回转窑传动齿圈振动分析及处理方法

回转窑传动系统主要由电动机、减速机、大齿圈和小齿轮组成。因回转窑属大型重载高温设备，其大齿圈易发生振动等故障而影响窑的正常运行。作者详细分析了回转窑齿圈振动的产生原因，并介绍了对应的解决处理方法。中铝股份山西分公司的生产实践表明，这些针对性的措施，均能有效地解决大齿圈的振动问题，从而保证了回转窑的正常运转。

Analyse of kiln drive ring gear vibration and the measures

Rotary kiln drive system is mainly composed of electromotor, reducer, big ring gear and small gear. Rotary kiln belongs to the kind of large-scale equipment that load great and endure high temperature, so its normal running inclined to be influenced by the vibration and other malfunctions of the big ring gear. Cause of the vibration and the corresponding measures are introduced in this paper. Practice of Shanxi Branch of Aluminum Corporation of China Limited shows that the vibration problem can be settled by these pertinency measures, and so guarantee normal running to the rotary kiln.
