仿生直齿轮的结构设计与性能分析

Structural Design and Performance Analysis of Bionic Spur Gears

为解决传统直齿轮在实际啮合工作中振动、噪声较大的核心问题,本着同时解决传统直齿轮重量较大且干摩擦的问题,以硅藻类为依据对传统直齿轮内部拓扑结构进行优化,并确定其最终三维结构;通过软件对优化后的仿生直齿轮的物理性能、模态频率等进行对比,从轻量化效果和减振两个层面验证了优化的效果。

In order to solve the core problems of vibration and noise in the actual meshing work of traditional spur gears,and in the spirit of simultaneously solving the problems of large weight and dry friction of traditional spur gears,the internal topology of traditional spur gears is optimized based on diatoms and its final three-dimensional stucture is determined;the physical properties and modal frequencies of the optimized bionic spur gears are compared through software's,and the effect of light weight and vibration reduction are The effect of the optimisation was verified at two levels.
