本文介绍用数学最优化方法,合理选择普通圆柱蜗杆减速器的主要参数一蜗杆头数z_1、蜗杆轴向模数(蜗轮模数)m、蜗杆特性系数q,使得蜗杆减速器在满足运用条件下,其蜗轮(轮箍式)齿冠质量为最小,以达到节约较贵重的有色金属、降低生产成本的目的。由于蜗轮齿冠质量小,减速器的重量也较小。文中分析了普通圆柱蜗杆减速器优化设计的五个方案,指出蜗杆头数的选择是影响目标函数值大小的关键因素,一般在设计资料推荐范围内选择蜗杆头数z_1的上限,有利于减小蜗轮齿冠质量、提高传动效翠,经济性较好。文中对优化设计过程作了较详细的叙述,这对机械设计人员熟悉优化方法,也有一定的参考价值。
This paper introduces the use of mathematical optimization method, a reasonable choice of the main parameters of a common cylindrical worm reducer a worm head number z_1, worm axial modulus (worm gear module) m, worm coefficient q, making the worm reducer to meet the conditions , The worm gear (wheel-type) tooth crown quality is the smallest, in order to save more expensive non-ferrous metals, reduce production costs. Due to the small quality of the worm gear crown, reducer weight is also small. In this paper, five schemes for optimization design of ordinary cylindrical worm reducer are analyzed. It is pointed out that the choice of worm head number is the key factor affecting the size of objective function value. Generally, the upper limit of worm head number z_1 is selected within the recommended range of design data, Worm gear crown quality, improve transmission efficiency Tsui, better economy. The paper describes the process of optimization design in more detail, which is familiar to mechanical designers and optimization methods, but also has some reference value.
