摘　　要：为了研究随机啮合参数对采煤机截割部齿轮传动系统振动的影响,以MG500/1180-WD型采煤机为研究对象,综合考虑啮合刚度、啮合阻尼、综合误差、齿侧间隙等因素的影响,建立采煤机截割部齿轮传动系统纯扭转非线性动力学模型,将啮合刚度、综合误差、齿侧间隙和外部载荷作为随机变量,运用变步长Runge-Kutta方法对系统模型进行求解,得出了系统动态位移响应的均值和均方差。研究结果表明,太阳轮、行星轮的振动位移均值及均方差随着随机间隙、随机啮合误差、随机啮合刚度的离散程度增加而增大;且随机间隙对轮系振动位移的影响程度最大,随机啮合刚度次之,随机啮合误差最小。研究结果为采煤机截割部传动系统的结构优化及其工作稳定性的提高提供了理论依据。In order to research the influence of stochastic meshing parameters on vibration of shearer cutting unit gear transmission system,taking the MG500/1180-WD shearer as the research object,considering about the effects of the factors such as meshing stiffness,meshing damping,combined error and gear backlash,the pure torsion nonlinear dynamics model of gear transmission system for shearer cutting unit is established,takes the meshing stiffness,meshing damping,combined error and gear backlash as the random variable,and also using the variable step size Runge-Kutta methods,the system model is solved,the statistical characteristic for the transient response of the system is obtained through statistic analysis.The research indicates that the mean value and mean-square deviation of the vibration displacement for solar wheel and planet gear increases with the degree of dispersion of the random clearance,meshing error and meshing stiffness,and random clearance has the maximum influence on the vibration displacement of planetary,random meshing stiffness comes second,the least influence is random meshing error.The research results provide the theoretical basis for structural optimization of shearer cutting unit transmission system and improvement of working stability.
