【摘要】 综合考虑变位系数、齿形系数、等强度及润滑条件等因素,建立中心距最小为目标的优化模型。并给出了一次接触强度优化和再次综合优化设计的方法,采用MATLAB的优化工具箱,对煤矿用JS40-25三级圆锥圆柱齿轮减速器的传动比进行优化分配,与原设计方案相比,该减速器中心距减小约12%,对减速器的优化设计具有一定的借鉴意义。更多还原

【Abstract】 Based on comprehensive consideration of def lection coeff icient, tooth prof ile coeff icient, equivalent strength and equivalent lubrication condition, the optimization model with objective of minimal central distance was established. In addition, the design method of one-time contact strength optimization and secondary comprehensive optimization was offered, and optimization toolbox of MATLAB was applied to optimize the distribution of transmission ratio of JS40-25 three-stage bevel-cylindrical gear reducer. In contrast with original design scheme, the central distance of the optimized scheme decreased by 12% or so. The method possessed some reference for optimization design of the reducer.更多还原
