【摘要】：矿山提升机使用的两级行星减速器不仅质量大,而且在使用过程中还会产生强烈的振动和过大的噪声,这严重制约了矿山提升机减速器的发展与应用。论文在国家科技支撑计划项目“大型矿山、起重传动装置轻量化及降噪关键技术研究”的资助下(项目号:2013BAF01B05),以某矿用提升机两级行星减速器轮系为研究对象,进行了减重降噪多目标优化。得到了较为满意的结果。论文的研究内容主要包括以下几个方面:①完成了两级行星减速器轮系多目标优化系统的系统分解与流程设计。②建立了齿轮的参数化模型和啮入冲击冲量的计算模型,并结合二者,得到了两级行星减速器轮系减重降噪的多目标优化模型。通过调整全局变量,在保证减速器可靠工作的前提下,采用非支配排序遗传算法进行计算,获得了质量和啮入冲击冲量的多目标优化结果,数据显示,轮系的总质量减小了6.48%,第一、二级的啮入冲击冲量分别减小了7.57%和13.84%。③对优化后的两级行星减速器进行静力学分析和动力学分析,并与优化前减速器的分析结果进行对比,结果表明优化后的两级行星减速器轮系的静强度满足要求,齿面接触应力、齿间动态啮合力、箱体表面加速度和箱体表面结构噪声都呈下降趋势。
[Abstract]:The two-stage planet reducer used in mine hoist is not only of large quality, but also produces strong vibration and excessive noise in the process of use, which seriously restricts the development and application of mine hoist reducer. With the support of the national science and technology support plan project "Research on lightweight and noise reduction of large mines, lifting transmission devices" (project number: 2013BAF01B05), this paper takes the two-stage planet reducer gear train of a mine hoist as the research object, and carries on the multi-objective optimization of weight loss and noise reduction. Satisfactory results have been obtained. The research contents of this paper mainly include the following aspects: (1) the system decomposition and flow design of the multi-objective optimization system of two-stage planet reducer gear train are completed. (2) the parametric model of gear and the calculation model of meshing impact impulse are established, and the multi-objective optimization model of weight reduction and noise reduction of two-stage planet reducer gear train is obtained. By adjusting the global variables and on the premise of ensuring the reliable operation of the reducer, the non-dominant sorting genetic algorithm is used to calculate, and the multi-objective optimization results of mass and meshing impact impulse are obtained. the data show that the total mass of the gear train is reduced by 6.48%. The impact impulse of the two stages is reduced by 7.57% and 13.84% respectively. The static analysis and dynamic analysis of the optimized two-stage planet reducer are carried out, and the results are compared with those of the reducer before optimization. The results show that the static strength of the optimized gear train of the two-stage planet reducer meets the requirements, the contact stress of the tooth surface and the dynamic meshing force between the teeth. The surface acceleration of the box and the noise of the surface structure of the box show a downward trend.
