三级行星齿轮减速器参数优化设计

Parameters Optimization of the Three-Stage Planetary Gear Reduction

摘要: 利用Lingo软件对盾构掘进机三级行星齿轮减速器进行参数优化设计，Lingo软件具有整数非线性优化功能，可直接得到最优解而不需要对齿数圆整，避免了圆整之后的解不是最优解的缺点。以太阳轮和行星轮的总体积最小为优化目标，以总传动比、配齿条件、齿轮强度条件、减速器外形尺寸限制等为约束条件，建立优化设计数学模型进行优化设计，使减速器减重明显。

Abstract: The parameters of the three-stage planetary gear reduction in shield tunneling machine was op-timized by Lingo software, for the Lingo software has the function of nonlinear Integer optimization, so the optimized teeth numbers need not to be rounded off and the error caused by rounding off is avoided. The optimizing model was constructed with the optimization objective of minimum volume of sun gears and planetary gears and the constraint of total transmission ratio, relationship of teeth numbers, gear strength and the size of the reduction to make the weight of reduction reduce significantly.
