减速机齿轮的模态分析和研究

Modal analysis and research about the gear of the reducer

针对锐进F系列这一典型型号的减速机,首先利用Pro/E软件建立了该型号减速机斜齿轮的实体单元模型。然后利用ANSYS软件对该减速机斜齿轮进行了静力分析并对齿轮的局部进行网格细化,之后对其进行振动模态分析,得到了该齿轮的前十五阶固有频率及模态振型。通过进一步的研究和改进,可以使其结构避免共振或按特定频率进行振动,从而提高工作效率和产品寿命。

Establish the gear model of the Ruijin F series reducer by Pro/E then use ANSYS to carry out the static analysis and separate the parts of the gear in detail.After vibration modal analysis,we get the first 15 natural frequencies and modal of the reducer gear’s vibration type.Through further research and improvement we can avoid structural resonance or make the vibration on the specific frequency which can make work more efficient and product life better.
