单级圆柱齿轮减速器的优化设计速器是各类机械设备中广泛应用的传动装置。传统的减速器设计一般通过反复的试凑、校核确定设计方案,虽然也能获得满足给定条件的设计方案,但一般不是最佳的。论文通过设计变量的选取、目标函数和约束条件的确定,建立了单级圆柱齿轮减速器的优化设计的数学模型,最后借助MATLAB的优化工具箱进行了优化计算,给出了优化设计程序,得到了优化参数。减速器? 轴承? 齿轮? 机械传动? 圆柱齿轮减速装置Abstract: The reduction gear is in each kind of mechanical device the widespread application transmission device.The traditional reduction gear design through repeatedly tries to collect, the examination determination design proposal generally, although also can obtain assigns the condition satisfiedly the design proposal, but is not generally best.The paper through the design variable selection, the objective function and the constraint condition determination, has established the single stage cylindrical gears reduction gear optimized design mathematical model, finally drew support from MATLAB the optimized toolbox to carry on the optimized computation, has given the optimized design procedure, obtained the optimized parameter.The level cylindrical gears speed reducer is located between the prime mover and the working machine mechanical drive.The commonly used reduction gear has standardized with the standardization, the user may act according to respective working condition to carry on the choice. Not only the reasonable transmission plan should satisfy the working machine the performance requirement, moreover also must work reliable, the structure simple compact processing convenient, the cost low, the transmission efficiency high as well as uses and maintains conveniently.
