摘　　要：多级传动系统扭振的固有频率对立磨的扭振状况具有重大影响。系统扭振频率完全取决于传动系统结构,控制和调整多级传动系统结构避开共振频率,既是多级传动系统设计的基本要求,同时也是减小振动的有效措施。文中求解出系统的固有频率,并进行多级传动系统激励频率分析,为立磨传动系统的安全稳定运行提供了参考。The toosional natural frequencies running of coal mill. It is the basic requirement of the multi stage transmission system greatly affect the for the driving system and effective measures for decreasing vibration to control and adjust the resonance frequencies of the structure of the driving system. The paper oclcutates the natural frequencies and points out the proximities of excitating frequencies in normal working. It will maybe the reference for safely running of coal mill.
