摘要：

针对矿用振动筛激振器斜齿轮容易磨损，以致严重影响煤炭洗选工艺进程的问题，文章建立了激振器斜齿轮-转子耦合系统动力学数值仿真模型，利用四阶龙格库塔法求解得出齿轮时变啮合力。根据混合弹流润滑特点，探索对比了主、从动轴的时变磨损系数、粗糙载荷比和油膜亏损系数在啮合过程中的动态变化特征，进而得到混合弹流润滑下主、从动齿轮磨损的深度以及磨损后的时变啮合刚度和时变齿侧间隙。通过将两者联合得到发生齿面磨损故障后激振器斜齿轮系统的振动响应，获得磨损故障导致x向、y向、z向上的振动响应规律，发现除系统非线性振动增强之外，x向、z向和扭转方向均对齿轮磨损响应敏感，该结论可为振动筛激振器齿轮磨损故障诊断提供理论依据。

Abstract:

In order to address the problem that helical gears of mine-used vibrating screen exciter is prone to wear and and seriously affects the coal washing process, this paper establishes a dynamic numerical simulation model of the coupling system between the helical gear and rotor of the vibrating screen exciter. The fourth order Runge Kutta method is used to solve the time-varying meshing force of the gear. The characteristics of gear wear under mixed elastohydrodynamic lubrication is analyzed. By combining the above methods, the vibration response of the exciter helical gear system is obtained caused by tooth surface wear. Thus, the vibration response characteristics caused by wear faults are obtained, providing a theoretical basis for the diagnosis of gear wear fault in the vibrating screen exciter.
