A lightweight and low vibration amplitude web design method was investigated to reduce gear weight and noise. It was based upon the relationship between length and orthogonality that the principal stress lines were designed at the gear web. By constructing a vibration control model with gear design parameters, the optimal distance was calculated. By offsetting the principal stress lines at the optimal distance, the lightweight gear web with the low vibration amplitude was then generated. A vibration experimental platform was built to verify the novel gear vibration performances, and it was compared with other gears with the same web's porosity to verify loading performance. The experimental results indicated that compared with the solid gear, the novel gear is 20.50% lighter and with a 29.46% vibration amplitude reduction.
研究了一种轻量级、低振幅的齿廓修形设计方法，以降低齿轮的重量和噪声。该方法基于主应力线与齿廓长度和正交性的关系，在齿轮齿廓上进行设计。通过构建带有齿轮设计参数的振动控制模型，计算出最佳距离。通过在最佳距离处偏移主应力线，生成具有低振幅的轻量化齿轮齿廓。建立了一个振动实验平台来验证新型齿轮的振动性能，并与具有相同齿廓孔隙率的其他齿轮进行了比较，以验证其承载性能。实验结果表明，与实心齿轮相比，新型齿轮的重量减轻了 20.50%，振动幅度降低了 29.46%。
