针对某BBD3854型双进双出钢球磨煤机减速机多次发生高速轴断轴、轴承损坏等问题,对磨煤机起动过程中的传动系统负荷进行核算,分析其影响因素。并计算出磨煤机起动过程下的载荷,且对此起动过程进行动力学分析,建立了其动力学方程,应用仿真软件Simulink对其进行仿真分析。 Aiming at some problems such as high-speed shaft broken shaft and bearing damaged on a certain type of double-inlet and double-outlet ball mill for BBD3854, the load of transmission system during the start-up process of coal mill is calculated and the influencing factors are analyzed. The load of the coal mill under the start-up process was calculated, and the dynamic analysis of the start-up process was carried out. The dynamic equations of the coal mill were established and simulated with Simulink software.
