摘　　要：以矿用提升绞车中的NGW型行星减速器为优化对象,按照力矩平衡条件,得到其功率平衡方程,采用啮合功率法得到2K-H型行星齿轮传动效率,以效率最大为目标函数,建立包含配齿条件、齿面强度等的优化模型。采用MATLAB软件对模型进行优化,结合配齿条件组合出4种优化方案,经对比分析得到的最终方案比优化前效率提高3‰。满足了行星减速器的优化设计要求,为行星减速器优化设计提供理论指导。NGW type planetary gear reducer in hoisting winch is selected as the optimization object for improving transmission efficiency. According to the moment equilibrium condition and the power balance equation,transmission efficiency is obtained. A design parameter optimization model is established with maximum efficiency as objectives,and the constraint conditions are established, including strength of tooth surface and tooth matching conditions. On the basis of preliminary optimization and gear matching scheme,four optimization schemes are set up. The efficiency is increased by 3‰. The optimization method meets the requirements of planetary gear reducer and provides the guidance method.
