摘要

齿轮作为机械工业必不可少的零件,其运转正常与否直接涉及整个机器的运转。为了验证直齿圆柱齿轮副啮合振动对齿轮运行状况的影响,利用ANSYS LS-DYNA齿轮运行情况与齿面点蚀剥落的关系,重点探讨了啮合作用力以及振动加速度。根据仿真结果可知,齿轮剥落会明显影响齿轮的运转状态,当齿轮存在故障时将会产生更明显的啮合力与振动加速度。
        As an essential part of the machinery industry,the normal operation of gears is directly related to the operation of the whole machine. In order to verify the straight tooth cylindrical gears meshing vibration on the influence of gear running status,the dynamic characteristics of faulty gear and normal gear are analyzed by using ANSYS LS-DYNA software. The relationship between gear operation and pitting erosion and spalling of tooth surface is obtained by comparision. The force of tooth cooperation and vibration acceleration are mainly discussed. The simulation results show that the existence of spalling has a serious impact on the normal operation of the gear,and the meshing force and vibration acceleration signal of the failure gear are larger than the amplitude of the normal gear.
